I just bought an 06 LT about a week ago and upgraded the front door speakers earlier today. When I put everything back together the passenger window no longer rolls up. It is stuck all the way down. I can't roll it up from either side of the vehicle. I can't hear the motor making any noise at all. Any idea what I might have screwed up?

 

I really need help on where to start troubleshooting guys. So far I know I have power to the switch and the motor. Except when I try it from the drivers side switch, then I only have power rolling down. I can hear the motor trying to roll it down when I press the switch on the passenger side and no noise at all when pressing the switch on the drivers side. Like I said, it is stuck all the way down. I tried connecting a new motor and the new motor also only spins one way the same as the old one.

 

This happen to me, just need to clean the connectors and a move the wires until it gets going.....i just had a bad connection....and lots of dirt

 

Same thing happened to my 04 Impala. Passenger window seemed stuck down.

Had power to door so I jumpered to see if window would go up it did so I knew window motor was fine.

I thought it was the switch but not.

Window would go down no problem but not up,, unless I jumpered.


Turned out to be broken wire inside rubber boot for wires from driver door to car body. Turned out to be an easy fix after a bit of troubleshooting.

 

What speaker did you install? It's possible the backside of the speaker, the motor, is pressed against the glass.
Does the drivers side window go up and down smoothly? Did the speakers install in the factory holes without modification?

 

hi like they said check all wire /plugs and door switch sometimes they get wet and dont make contact
