Hi guys - I've got a strange power window problem that I've tried to fix but with no luck! (93 C1500 ECSB) Three times now I've put the windows down and they stop, and won't go back up for about 30 to 45 minutes (haven't timed exactly)
1. This seems to happen when both switches are pushed at the same time. ie. either both drivers side, or the drivers side and passengers at the same time.
2. The windows stop working and won't move. neither up or down.
3. If I turn the truck off and on again the drivers side will go up very slowly, less than an inch and then stop. Passenger side nothing.
4. After about 30-45 minutes the windows work again like nothing happened.
The last time it happened I noticed the radio (aftermarket stereo) turned itself off and on again. So its like pushing the two switches at the same time draws too much power and causes something to trip. Not sure why the radio would come back on again by itself though. Like a power hiccup.
Seems as if a "breaker" resets itself after the 30/45 minute wait.
Checked all fuses - good. Swapped the relay with the one next one to it on the fuse panel, no change.
Is there a breaker somewhere, or some kind of capacitor? I checked all the wiring diagrams but couldn't find anything.
Thoughts???
