Drivers side window and locks not working

Hello,

It sounds like the vehicle security module is out. to be sure here is a guide and the door lock wiring diagrams so you can test the connection to confirm the issue, also I have included the VSC location as well.

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

I tested the drivers power lock switch using a jumper on the lock and unlock wires. I could hear the VSM clicking. All windows except the drivers function correctly. Crazy part is that every now and then the drivers door will unlock from the key fob or the master entry buttons. Most of the time it will not function.

Yep, sounds like the VSM is out. I would try a new one to see what happens. You can try a CAN scan as well. here is a video to help confirm the failure. you can get a CAN scanner from amazon for about $40.00.

Please run down this guide and report back.

Where is the VSM located and would you happen to have a part number?

The VSM is located on the passenger side under the dash. here are the instructions on how to change it out. No part number, you will need to call the dealer for this part. Check out the diagrams (below). Please let us know what happens.

Thanks. Okay, I found the VSM "Ford (4L1Z-15604-AD)".
do I use a CAN scanner to download the codes from the ODBII port?

Yes, Check out the instructions that came with your scanner. Do you have a pictures of it?

I need to order one lol. Shopping around for one.

Okay, I scanned the vehicle using FORSCAN software.

At some time in the past a corrupt message was received from the PCM. Try clearing the DTC to see if this DTC re occurs. If it does then carefully check the SCP wiring and run the PCM diagnostic.

Run self test.

All CMDTCs

Fix all relevant DTCs then clear codes and retest.

Note:

DTCs that start with 'U' are faults which occur during module-to-module communication.

Modules should never be replaced based only on a 'U' code. These codes do not always indicate a problem, and can be caused by normal diagnostic functions, carried out on the vehicle.

Fix all relevant DTCs then clear codes and retest.

I just got the extended lic for the FORSCAN software... This will let me see into the PATS and other modules that were restricted before. I will post those scan results when I get home from work.

Please do.We are interested to see what it is.

So no joy.. The ELM327 adapter can't seem to read the UBP bus where the VSM among other things live... I confirmed that by scanning my 2005 Mustang and it found everything.

So many voltages out of range. is the battery okay? Here is a guide to check the battery:

Is this the only thing you see wrong with the car? Drivers side window and locks not working?

Please run down this guide and report back.

The battery was replaced about three weeks ago.
Yes, only drivers window and all door locks not working.

There is an accessory delay relay I would check. here are the wiring diagrams for the windows so you can see how the system works and the relay location so you can test it.

Check out the diagrams (below). Please run this test and get back to us.

will do that.
keep in mind that I can hear the clicking sound when I press the door lock/unlock button.

Can you please shoot a quick video with your phone so we can hear the noise? that would be great. You can upload it here with your response.

Video attached... to me it sounds like it's coming from the VSM.

Nice work on the video, can I ask which phone use used example: IPhone 6 ? The noise it making like it keeps cycling trying to process the protocol. I would replace the VSM to see what happens. BTW battery cables clean correct voltage getting to the VSM?

Samsung Note 9.
good question on the voltage to the VSM... would you happen to have the wiring layout so I could test that?

Sure do in the first post of the thread click on the images. Let me know what you find.

Update: I had my friend that owns Michael Auto Cares in Tomball, TX. install and program the new VSM. No change... Still no power locks and drivers door window not functioning.

So he started looking a voltages.... Green wire in the wiring diagram that runs to the VSM is supposed to supply 12v to the Drivers Window and the Power locks was only showing 5v. When the power lock button was pressed it dropped to 0v. So started tracing back on the passenger side that runs along the body channel and found the green wire in the picture was broken.

Issue resolved

Glad you could get it fixed, that kind of problem can be tough. Please use 2CarPros anytime we are here to help.

All power door locks not working. Had dealer install a new VSM without a diagnostic test. Still not working.
Dealer had it for 2 days then called me to tell me he would have to start charging me for diagnostics and searching for a short.

No blown fuses or relays- all are good.
No water evident at fuse box.

The original VSM was clicking and I can hear the same clicking from the new VSM when using the door lock switches and/or the remote.

Looked at all wiring harnesses inside driver door, under dash on both sides, and at both doors at hinge location. No damaged wires found.

you say you already had the vsm ( vehicle security module) replaced,but were there any codes stored in it? I believe the fuse number 30 in the interior fuse box feeds the power to the vsm,but you say that it is ok.this is an involved system which contains inputs and outputs from multiple modules,switchs,ect.it really would be your best bet to pay a pro with the correct tools and training to diagnose this issue for you.because someone who doesn't know what the are doing can very quickly fry a module and cost you more than the diagnosis would cost.

I thought I was doing the right thing by taking it to dealer but I'm not comfortable with them.

Does anyone else have any recommendations?

I gave a donation and was expecting a better response to help with the situation.

Battery now drained down overnight so something is obviously wrong.

On mine the issue was a green wire that supplies power to the power locks and the drivers window via the VSM and I too could hear the clicking sound.

This wire was almost all the way broken... it had like a couple of strands holding it together.
Its tied to the bundle that runs along the passenger side well under the kick plate. To test that this was the issue we jumped it and everything worked great. So we spliced it and sealed. All works fine.
I did find that water was leaking... the pad underneath the carpet was wet on the passenger side where this wire bundle lives.

Best of luck
