The window goes down but will not go up?

Hi,

I am basing this on the problem related to the driver's side front window.

First, I feel you have a bad switch. Here is how it works. I realize you have power from the switch to the motor, but if you are checking only one wire, which is only going to allow the motor (in this case) to go down.

For the window to go up, the direction of power (polarity) has to change directions. So, one wire will get power for the window to go down, and the opposite wire on the motor will get power to make the window go up. Regardless of which wire gets power, it is the opposite wire that functions as a ground.

Take a look at the pic below. See if you get power to one of the wires when the switch is in the up position.

Let me know what you find.

Take care,

Joe
