My wife told me ... sometime in January, that the rear window wouldn't go up or down. Since the wiper worked, and the defrost worked, I wasn't in a rush to do any investigating. I appreciate the responses above to where to look for the TSB, and it was quite helpful, although not exactly the same problem.
So today.....july 29th, I finally got to take a look at the truck. First I followed the tsb for the access information, and then diverted just a little bit. After removing the panel, I took my test light and disconnected the connector that ran to the yellow sheathing covered wire that fed into the lift motor
With the help of an assistant (my lovely wife), I tested to see if the truck was supplying power to the motor or not. With the test light grounded, I pinned the pink wire coming out of the harness that led to the connector to the motor. The test light came on, and the relay was clicking in the ecu. So, I'm getting power to the motor..
An old chevy trick.....
I reconnected the wire harness together, an took a faithful hammer to the motor housing itself. One wack with the hammer, and the window began working. Apparently, the brushes are bad in the motor, hence the lack of up or down movement of the window.
An old man (something that I'm working on being in the near future) told me to KISS......
Keep it simple stupid !
Always look for the simplest solution first.... then get more technical.
