Door locks will not operate correctly?

Good afternoon,

I attached a wiring diagram for you to view. The door module may be the issue but it needs to be confirmed.

You need a scan tool that can read the door module to verify the signal from the switch is being sent to the module. Then the module sends a signal to the body control module to work the other locks on command.

You can check the fuse I listed but the real check needs to be done with an advanced scan tool.

Can you recommend a good scan tool?

Snap on Apollo. Top of the line for scan tools and does everything. Very pricey but worth it.

It would be worth having a shop check it for you and at least diagnose the issue.

Roy

Thank you for this info ASEMASTER6371, the Snap on tool is a little rich for the use I would have for it. I am guessing a $500.00 to $1,000.00 OBDII reader will not help with this, like the Autel. I appreciate the info. Stay safe.

No, it will not. It is not as advanced as it needs to for this information.

You are welcome.

Always glad to help.

the horn has been randomly going off on. also, noticed out headlights flicker on and off but when i put it on high beam then back on low they do fine. we changed the horn relay which was fine, then the totally integrated control module which was not. checked all the wires we could see and find no issues. not sure where to go from here. oh and now my windshield wipers turn on when starting and cutting off the vehicle. also, power locks and windows do not work.

Did you use a new TIPM or a used one?
Have you tested the front control module, it is bolted to the front of the TIPM. It controls most of the items you're having problems with. Also, check the grounds next to them. If they fail you get various problems as the control voltages start fluctuating.

The other issue could be odd data on the CAN buss. That takes a break out box and analyzer to look at.
I would take a look at the data on the buss and off a good scan tool and see what is being commanded to do what.

Also check the actual power distribution center, they fail a lot as well.
Hard to do much of that testing without a scan tool that let's you watch or command the various modules though.

Thank you Steve for your reply! The TIPM was from eBay so used. I have to say before we put that one in all that was wrong was the horn and lights flickering then once we put in the new used TIPM the vehicle would not start. so we put the old on in and it started right up only to notice the windshield wipers went off on start and shut off of the motor. Also all of the sudden the power windows and locks stopped working as well. We have checked the ground wires but honestly not sure we could be missing something. I think we will invest in a scan tool right now that looks cheaper then some possible fixes on this thing!

Do not rush into buying a scan tool until you decide how far you want to go in DIY repairs. The tool needs to be able to view live data and watch as items are controlled, most of the lower priced ones don't do that very well.
Get a copy of the factory service manual. There is a copy online free at allcarmanuals (only Jeep they have!) It has a lot of tests you can do with simpler tools and gives you an idea of what else you need.

Plus you can always ask here.

Will do thanks!

Interior lights stay on while driving and the driver door is the only one that locks automatically. I have to cut lights off with dimmer switch and then there are no lights on the panel to see speedometer at night.

Hello,

It sounds like you have a fuse #15 fuse that is out and needs to be checked. Here is a guide to help you get the job done:

Here is the location (below).

Please let us know what you find.

Cheers, Ken

Seem to have the same exact problem.
Just started this morning when I went out to go to work. Will check the fuse this afternoon after work. Hopefully is a simple fix.

Let me know on the fuse because you could have a TIPM going out which I can help you fix.

Started my car leaving the office today. Took me a while to notice my dome lights wouldn't shut off. All the lights were on, and the only way to turn them off was to turn the dial on my headlight arm to the lowest setting before shutoff. This obviously dimmed everything in the car to the minimum.

Shortly after, I realized that my automatic windows and locks were not working, and the lights on these panels were not lit up. I did not check doors beyond the driver side.

My radio was on and working fine. My car started fine. The doors lock and unlock with the fob. I drove to work this morning and did not notice this. Seemed to come out of nowhere.

Hello,

It sounds like the drivers door module is out which is common. Here are diagrams below to help you fix it. I does not say you will need to have it programmed so it should self initialize. If not it should cost about $130.00 to have it done at a shop. Check out the diagrams (below). Please let us know what happens. Cheers, Ken

Thank you, Ken!

By module, you mean the entire power switch console? If so, part 5JM60DX9AB is what I found. Would hate to buy this part, for $200.00, only to find it's not the issue. But, I guess that's the name of the game.

Yep, that's why the guys in the dealer have an advantage they install the parts and then put them back if they don't work. Let me know. :)

The issue has been resolved, by simply replacing the module. I purchased an OEM part for $55.00. Removed the door panel, replaced the unit, put'er back together and everything works just fine.

Only issue is, all but two clips broke. These were likely the original clips. I will replace these in due time. For now, the panel is on there good enough.

Thank you, Ken! You saved me some money!

Nice work, we are here to help, please use 2CarPros anytime.

Hello,

The remote door lock/panic of my vehicle is not working any more. Changed the battery on the remote itself and not working.

Battery of the car went down for a week or so, and I had to use a booster to switch on the ignition. Is something like that, I mean a long period without battery, related to the remote not working any more?

Thank you

When you jumped the car did you connect the jumpers correctly, not backwards? If okay lets check the security system fuses (#22, 28, 7 and 18). Here is a guide to help us get started with the security system wiring diagrams and fuse locations below:

https://www.2carpros.com/articles/how-to-check-a-car-fuse

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Cheers, Ken

Checked fuses. All okay. However, found this weird button and switch in the fuse box. What that would be?

Oh boy, this looks like an aftermarket alarm system has been installed which cause all kinds of problems. Can you follow the wiring to see where it goes? Try to find the control box and take a picture so I can see what's going on.

The only window a lock that works is on the front driver side. Have checked fuses and wires in the door jam (none were bad, and all wires are intact) and have replaced the master switch. Still the only door working is the front driver door.

Hello,

It sounds like the passengers door module is out but to be sure here is the testing process and the door lock and windows so you can see how it works. (below)

TESTING

If the problem being diagnosed is a rear door window that does not operate from the rear door switch, but does operate from the master switch on the driver side front door, (Refer to DIAGNOSIS AND TESTING - POWER WINDOW SWITCH ). If the problem is a passenger side front or rear window that operates from the switch on that door, but does not operate from the master switch on the driver side front door, use a DRB scan tool and the proper Diagnostic Procedures to diagnose the circuitry of both door modules and the PCI data bus. For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

Disconnect and isolate the battery negative cable. Remove the trim panel from the front door, but do not disconnect the door wire harness connectors from the door module. Go to Step 2.
Check the 15-way door wire harness connector for the door module to see that it is fully seated in the door module connector receptacle. If OK, go to Step 3. If not OK, properly connect the 15-way door wire harness connector for the door module to the door module connector receptacle.
Disconnect the 15-way door wire harness connector from the door module connector receptacle. Check for continuity between the ground circuit cavity of the 15-way door wire harness connector for the door module and a good ground. There should be continuity. If OK, go to Step 4. If not OK, repair the open ground circuit to ground as required.
Connect the battery negative cable. Check for battery voltage at the fused B(+) circuit cavity of the 15-way door wire harness connector for the door module. If OK, go to Step 5. If not OK, repair the open fused B(+) circuit to the fuse in the Power Distribution Center (PDC) as required.
If the inoperative window is on a front door, go to Step 6. If the inoperative window is on a rear door go to Step 9 .
Disconnect and isolate the battery negative cable. Disconnect the door wire harness connector from the inoperative power window motor wire harness connector. Check for continuity between the front window driver up circuit cavity of the 15-way door wire harness connector for the door module and a good ground. Repeat the check for the front window driver down circuit. In each case there should be no continuity. If OK, go to Step 7. If not OK, repair the shorted front window driver up or down circuit as required.
Check for continuity between the front window driver up circuit cavities of the 15-way door wire harness connector for the door module and the door wire harness connector for the power window motor. Repeat the check for the front window driver down circuit. In each case there should be continuity. If OK, go to Step 8. If not OK, repair the open front window driver up or down circuit as required.
Reconnect the 15-way door wire harness connector back into the door module connector receptacle. Connect the battery negative cable. Connect the probes of a reversible DC digital voltmeter to the door wire harness connector for the power window motor. Observe the voltmeter while actuating the switch for that window in the up and down directions. There should be battery voltage for as long as the switch is held in both the up and down positions, and no voltage in the neutral position. If OK, (Refer to DIAGNOSIS AND TESTING - WINDOW MOTOR ). If not OK, replace the faulty door module.
Check the rear door power window switch continuity. (Refer to DIAGNOSIS AND TESTING - POWER WINDOW SWITCH ). If OK, go to Step 10. If not OK, replace the faulty rear door power window switch.
Disconnect and isolate the battery negative cable. Reconnect the door wire harness connector to the rear door power window switch. Disconnect the door wire harness connector from the inoperative power window motor wire harness connector. Check for continuity between the rear window driver up circuit cavity of the 15-way door wire harness connector for the door module and a good ground. Repeat the check for the rear window driver down circuit. In each case there should be no continuity. If OK, go to Step 11. If not OK, repair the shorted rear window driver up or down circuit as required.
Check for continuity between the rear window driver up circuit cavities of the 15-way door wire harness connector for the door module and the power window motor wire harness connector. Repeat the check for the rear window driver down circuit. In each case there should be continuity. If OK, go to Step 12. If not OK, repair the open rear window driver up or down circuit as required.
NOTE: The door module feeds battery current to both terminals of the rear door power window motors when the power window lockout switch is in the Unlock position, until the master window switch on the driver side front door is actuated. The door module feeds ground to both terminals of the rear door power window motor when the power window lockout switch is in the Lock position, until the master window switch on the driver side front door is actuated.
Reconnect the 15-way door wire harness connector for the door module to the door module connector receptacle. Connect the battery negative cable. Check for battery voltage at each cavity in the door wire harness connector for the power window motor. Each cavity should have battery voltage when the power window switch is in the neutral position. Each cavity should also have battery voltage in one other switch position, either up or down, and zero volts with the switch in the opposite position. If OK, (Refer to DIAGNOSIS AND TESTING - WINDOW MOTOR ). If not OK, replace the faulty door module.

I have a couple things that are going on with my vehicle right now. One is my door locks do not work the drivers side will lock but not lock any other doors. Also, the passenger side window will not roll down at all, the inside lights will not turn off automatically, I have to switch them off at all times. And now the outside of the car. when my head lights are on the only light that is on is the passenger side light, I do not have brake lights when the lights are on and when they are the only light that comes on is the drivers side. I have been told to change all the bulbs, and to look at all the sockets. Has this happened to anyone else and what did you do to fix the problem?

Hi Sherry,

This sounds like the BCM has gone out and needs to be replaced. Here is the location of the unit you will need to have it programmed by a shop for about $130.00 bucks.

Please let us know what you find. We are interested to see what it is.

I have a 2004 Jeep Grand Cherokee. All of a sudden, the automatic door locks quit working except for the drivers door. At the same time, the passenger windows would no longer work and both of the keyless entry key-fobs also quit working.
Has anyone got any information regarding these problems? Is it possible that these issues are related and if so how?
I really need to get this fixed since this is my daughter's vehicle and the only way to lock the rear lift gate is with the automatic locks. She is leaving to go back to school very soon.

Thanks.

Check for bad grounds. Check the body control module.

I have a 2004 Jeep Grand Cherokee. Trying to find out if my problem had been on recall. The issue is that I have had the following repaired twice and now it has occurred for the third time. The remote does not lock the car. When I try to lock it the inside lights remain on and the doors do not lock. All the buttons on the driver door do not work. I have to insert the key in the driver door to lock the door. However, the remote will lock the back ddors. The alarm light as well as the alarm will not activate. Windows can not be rolled up or down.

Pull the rubber boot back and check for broken or frayed wires between the driver's door hinges. The wires typically break very near the door or the "A" pillar. The harness can be unbolted to make repairs easier.

I have the Laredo model and I am having problems with the door locks. the main door will unlocking and lock when I push it, but it will not unlock any of the other doors on the truck. I see everybody having problems with windows and door locks but mine is just the door locks not working for all the passenger doors. I was wondering if anybody had any ideas on what to check for?

The first thing I would check is the switch itself. Check to see if power is being properly distributed from it. Also, check for broken or damaged wiring between the door and door frame. Keep in mind how many times the wiring moves there when you open and close the door.

I hit a large deep hole in the snow over this winter on the right side of my jeep, and now my power door locks door chimes entry lights (above or below) and radio quit working I took the right side of the dash apart, and didn't see any visible problems where do I go From here? On a fixed D A V income so any help would be greatly appreciated

check things in pic and fuses maybe the fuse block has loose wires on rh side. also check ground for doors then have scanned may be the remote module.
