Welcome to 2CarPros.

The power window motor direction, up or down, is changed by the way power flows to the motor (polarity). So, since it works one way, it, in theory, should work the other. That leads me to saying most likely, either there is a bad switch or one of the wires is damaged or disconnected at the motor.

If you look at picture 1 below, I highlighted the window motor and its connection. You need to remove the connection from the motor and check for power. You can use a test light or volt meter to do this.

Now here is how this will work. When you remove the plug from the motor, it will look like pic 2. Note in the picture the pins are described as pin A and pin B. When you press the switch for the window to go down, pin A should have power. When you press the button to go up, pin B should have power. Pic 3 below shows the left window but the right one that you have trouble with is the same.

Now, you will have to remove the door panel to access the motor and wiring. Here are the directions for replacement of the door panel. It shows how one is removed and replaced. The remaining pictures correlate with these directions.

Here are a few links you may find helpful when testing for power.


Let me know what you find and if the window works from any of the switches or the problem is limited to just one.
