There is no fuse in the integrated fuse box labeled for wipers per the owner's manual. And I can't find the relay it is not in the box. I have not located it under the dash but could be there. I don't even know what it looks like, is it a little black box. The mechanic told me there should be a fuse also so the relay wouldn't blow? Sorry so long.

The wiper fuses is #2 - 20 amp in the TIPM. What is the issue you are having? Unfortunately if it is no wipers and the fuse is good but the washer does not work it is likely that the internal board of the TIPM has failed. To repair that you replace the TIPM. Check out the diagrams (Below). Please let us know what happens.

The wipers only work on the high side and run really slow. Low and the delay don't work at all.I have replace the wiper motor and the switch in the steering column and still have the same problem?

Your wipers are controlled by a TIPM. You can check the connector pins for corrosion, but chances are you'll need a new unit. Check out the diagrams (Below). Please let us know what you find.

Sometimes it seems when the weather is cold, that the wipers will not work at all. Doesnt matter what setting(low, intermittant, or hi) this could go on for a couple hours(of not working) to a couple days, then all of a sudden they will work fine.

Any thoughts?

Hi,

If the start working again, it wouldn't be a fuse. Since it happens when it's cold, I suspect you have a connection issue. However, let's start by checking the wiper relays.

If you look at pics 1 and 2 below, I included the entire wiring schematic for the wiper system. I need you to locate and check the wiper relays in the underhood fuse box. First, remove the relays and check for corrosion where the connection is made. Also, make sure none of the pins are pushed in or damaged.

If everything looks good, see if there is another relay in the box with the same part number and switch them. Do this when the wipers are not working to see if it makes a difference. If you look at pic 3 below, it shows the relays to check (highlighted).

If there are no relays that are the same, here is a link that shows how to check one:

https://www.2carpros.com/articles/how-to-check-an-electrical-relay-and-wiring-control-circuit

Next, at the rear of the engine (driver's side) is a black wire which is ground. Check to make sure it is clean and tight, free of corrosion. Note: That ground is for both the relay and the motor. If it looks corroded or rusty, remove it, inspect the connector, and clean the surface where it mounts to get a good ground.

Start with this. If you find the relays make no difference, we will then need to check the wiring from the integrated power module.

Let me know what you find or if you have other questions.

Take care,

Joe

My wipers quit working. I changed the wiper motor and multi-function switch, checked the fuses and relays and tested for power. I have power going to the motor and the switch, but nothing happens when I turn them on. Out of ideas!

Hi and thanks for using 2CarPros. Com.

If you have power to the motor, it can only be a few things. Either the new motor is also bad (which is unlikely), you do not have a ground or the totally integrated power module (TIPM) is bad. I have attached a wiring schematic. You will see that power to the motor comes from the TIPM. It is not uncommon for you to show power when checking with a volt meter or test light. However, when a load is placed on the TIPM, it fails. What happens is there are several tiny pin connectors which corrode and break or lose a good connection. That is when the problems start. It is not the greatest design.

When you check for power to the wiper motor, probe the wire and check if the voltage drops. If it does, check for connection issues or a bad ground.

The grounds related to the motor are G104 and G106. I attached a picture of their locations. G104 is in the left front of the engine compartment and G106 is located in the left rear of the engine compartment.

I hope this helps. Let me know if you have other questions.

Joe

You first should check to see if there is power to the wiper motor. If you do, the motor is either bad or has bad ground. If there is no power, follow the power supply from the motor back to the switch to ensure there are no broken wires. If all is good, check the switch (multi function) on steering. Make sure there is power to it. If there is and none out, the switch is bad.

The windshield wiper acts up on the intermittent setting. It works fine on continuous wipe, both low and high speed. When the wiper is turned on the first position is intermittent. It is then that the wiper blades will rise to the vertical position and sit there. Several seconds later they will go right down and then back up just a couple of inches. Then this pattern continues, each time going through the same amount of time but stopping in a different place each time. I'm guessing that there is an intermittent relay at fault. If this is so, where will I find the controller, please?

I am having the exact same problem with my 2001 Ram 1500 V8 5.2 with 61K miles and have been told it was the wiper motor? I have also been told it may have been a central timer module? So, my question is which one would it be and if its the central timing module where is it located?

I replaced the motor and it's fine, now. It cost me $82.17 for the motor and it took about 30 minutes to replace it. Easy job. The guy I bought the truck from told me that he remembered trying to clear the windshield of frost and snow. The blades were stuck to the glass but it kept trying even after he turned off the ignition, and damaged the park switch which is built in to the motor.

Need to know what I can do to see why my windshield wipers are not working? I was recently driving in the rain when the windshield wipers stopped working. They just stopped upright on the windshield. I tried turning the switch off and on and they would not work. Also, I tried the washer/rinser switch and that worked. Is it the motor or did something short out in the rain? I do not know what is wrong with it.

The wipers were working fine and than they just quit. I checked the fuse and found it was blown so I replaced it but it had blown that one to just as I tried the wipers again.

Hi:
Disconnect the power supply to the motor and try a new fuse to see if it blows without the motor being connected. If it doesn't, chances are it's the motor. If it does, there is most likely a short in the steering column.

Let me know what you find.

Joe

Last winter I turned on my wipers when there was too much snow on the windshield. The wipers stopped working, I checked the fuse and it was blown. I replaced the fuse and turned on the wiper, leading to the fuse being blown again. What is the likely cause of this issue? Could it be my wiper motor? What steps should I take to identify and resolve the issue? Thanks

WIPER FUSE BLOWS Disconnect wiper motor. If fuse does not blow, replace wiper motor. If fuse blows, check wiper switch or wiring.
