I have a 1989 chevy k1500. I was wondering if anyone has any suggestions on how to go about my passenger power side window. Just today I rolled down my passenger side window from my side and the window went down. But after rolling it down i could not roll it back up up from either side. my driver and passenger side window switch wouldnt roll it back up. They both worked all the time. I tested the motor to see if it was still good because i didnt hear anythng so i took off the panel and cut the two wires connected to a harness that was plugged into the motor pr i think its called a regulator and plugged it up to a battery and it rolled right up. Is there like a fuse for the window? Or maybe a bad connection somewhere?

 

Just try giving the side of your switches on your driver side door a thump with the butt of your fist. Works for me.

 

something similar happened to me not to long ago. how i fixed it, i pulled my door off to get to the wiring harness. unplugged the connection and plugged it back in and its been working fine ever since.
