Rear window goes down on it's own

[1100russ]

Hey guys, has anyone had one of their rear windows just start going down on it's own? Tried to search but couldn't find anything. Just driving down the road over the weekend, passenger rear window starts lowering. I closed it. Did it again immediately. I finally locked the windows because it kept happening lol.

I had a similar problem for up though. I would hear a random click from the back seat like somebody tapping Morse code.

Child lock stopped it and I figured out It was the window trying to roll itself up.

It is almost certainly in both cases a failed window switch that is bridging closed on bumps.

You can pull the switch out (use plastic pry tool they just lift out)

Pull the connector. If it stops it's almost certainly inside the switch. If it doesn't stop it's a short in the wiring.

Praise Jesus for the child lock.

I think mine dried out and stopped shorting I haven't noticed the click when child lock is off in a long time. (though my child lock is almost always on. Apparently it's positioned right where I like to rest my pinky finger)

This was my case... Although it didn't work at all anymore.
