Hi!! I have a 2005 Cadillac deville 4 dr. The rear window on the drivers side will not go up or down.

Mechanic's Assistant: Are you fixing your DeVille yourself? What have you tried so far?

Yes and I have tried. I got a new regulator, motor and all and installed it. I still got the clicking but no up and down.

Mechanic's Assistant: Where exactly do you think the noise is coming from? And how long has this been going on?

It appears that the clicking is from the control panel in the door.

This would mean there is a poor power/ground or rear drivers side door module has failed. Monitor power/ground at module while trying to operate window to verify it maintains good power/ground. If not check wiring in door jam, if good replace the door module. Here is a connector diagram to help with testing. Let me know if you have questions, thanks.
