Rear windows
I have a 08 Tahoe ltz and the rear windows won’t roll down only from the master switch what can cause this |
You're new here, I'm trying to decipher your post. If your rear windows do not lower using the master switch but do lower/raise from the rear door switches, then sounds like a bad master switch.
Do the rear windows raise using the master switch? |
They roll up/down with the master switch but don’t roll up/down with the rear door switches |

If so, and rear switches don't work, then switch(es) are bad. If not, maybe wire not connected at the master switch. A wiring diagram for 2008 would help you. |
Check to make sure the master switch panel lock out is not engaged for the rear windows. There is a button/switch on the master panel that you can use to lock out the back windows to keep your kids or pets from rolling down the windows.

Good point; I drive our GMC so little I forget about modern safety stuff like that. Unfortunately, every time I try to look up anything in the owner's manual, it takes me from chapter to chapter.
