Windshield wipers not working there is no fuse?

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.

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.

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:

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,

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.

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.

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.

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