I have a 2006 Hummer SUT mid-gate window will not go down . Fuse is Good. whatcan icheck next.

 

Make sure it didn't somehow become unlatched a little by vibration or whatever. If that's not it, take it to the dealer. It's still under warranty right?

 

definately agree with the trip to the dealer...but..in case it isn't under warrenty then check out the usual problems with any window...switch,motor,off tracks. Basically the first thing to do is set a volt meter across the motor and hit the switch, if no power is present then the problem is at or before the switch. If motor has voltage then problem is at or after the motor.

 

Also try the express down switch. Just in case the regular switch is bad.
