1988 K5. Was off-roading pretty hard yesterday (first time I have had it in those conditions). During a particularly bumpy part of the trail, the windows started going up on their own. I would put them back down, we would hit another rough section, and up they would go. I just took apart the door panel, and I could not replicate the problem in my driveway.

Any ideas are appreciated.

Thanks

 

sounds like maybe a short somewhere, wires touching together?

 

yeah check the wires going through the door jam and under the dash. when you are flexing the body like that who knows whats going on

 

Thanks guys. I traced out the wires as much as I could (kinda lost them in a bundle coming out of the door and under the dash) and so far cannot find anything strange. I even started it and jumped up and down on the driver's door sill to simulate violent movement and could not reproduce the problem.

I was surprised mainly because I figured I would have blown a fuse. Hell, the windows probably went up on their own a good 25 times that day.

Oh well, guess I was just hoping someone had experienced the same issue and could point me to some widget causing it.

I really appreciate the assistance.
