GM Pontiac Grand Prix GTP Power Window Motor & Regulator Picture Illustrated Repair Guide - Page 2 of 4

here you go, write up on how to replace regulator and motor although its easier to just try it by guessing. took me 1 hour to switch out the regulator and motor and then back again because it turns out wasnt the problem

If its not the switch and its not the regulator/motor. What else could it be that causes the window to not respond 50% of the time when you press the upswitch? Very rarely as well the window will go down by itself and the motor seems to click and tick sometimes...

I've tried the cleaning the switch job and ive tested with a brand new regulator/motor

I cant figure it out
