I changed the motor, driver side window is still not working. Passenger side works as it usually does.

It just randomly died on me. It was working fine as I can remember before it stopped working. The window is stuck in the up position.

 

Switch, wiring, motor itself (usually the case).

 

The wiring connector on mine is finicky. reach in and move it while using the switch. If it moves at all you found your culprit. I have done probably 50 different cars and a few of them had this problem.

 

Anything else? I've tried what the poster above mentioned with no luck. What else could make a driver side window motor fail?

 

It's time to replace the motor.

 

Poor window adjustment, excess friction, broken regulator parts, use.

 

window regulator went bad on my 01 z28 NOT the motor

 

heres the invoice with the part # on it. yea i know it says motor/regulator but that was for the warranty . the code for the repair was the same. if you reference the # it comes up as a regulator

 

Where is the regulator?

 

its the mechanism the motor hooks up to that operates the window here a link with the picture of the part http://www.rockauto.com/catalog/raframecatalog.php go to your car and its under "body and interior" catagory

 

OK. So I guess it's either the regulator or the switch.

So I think if it was the regulator, I wouldn't be able to to push or pull the window down by hand with the motor out?
