HELP!!! Rear driver window-erratic movement

aaron · #1 03-16-2009, 02:44 PM

I need some help guys. My rear drivers window will automatically roll down erratically without anyone pressing the window down. It will roll a quarter of the way and sometimes all the way after i roll it back up. One way i stop it from rolling down is to press the window lock button on the drivers side. Once i release the window lock the window would roll down to quarter, half, or all the way. Eventually it will go all the way. Sometimes when the window lock is release about 1 or 2 seconds the window would act up. I dont think this would be an regulator issue sense it is able to roll back up by the drivers button. Thanks for anyone that can help me.

I would first try to replicate the problem by knocking on the rear door panel near the switch with the window rolled up and window lock off. Depending on the result I would then take off the door panel, and disconnect the rear switch to eliminate that it is the the switch that is faulty.
I am leaning more towards a sticky rear switch.
Try spraying some contact cleaner before removing the door panel.

so i tried to let it roll all the way down and it sounds like the clicking noise from the rear kept on clicking that it wants to roll down some more when its at the max. Do you know what this may be? I already tried to knock the door panel with the window roll up. I want to try everything before taking the panel off. thanks
