04 base deville- dead rear driver left door- window and locks do not work
This a great forum. Was able to troubleshoot and repair rear dead door. Just thought I'd give back a little.
Replaced window regulator with no problem about a month ago. A week later, the window and locks stop working.
Fuse was okay, window motor and module also okay.
When I depressed window switch, there was a click sound, but nothing happened.
I have zero electrical ability, nor tools to troubleshoot currents, etc.
Using these forums, learned that ground wire at rear door pillar sometimes breaks or frays.
Removed boot covering wires at pillar revealing that ground wire was broken at harness.
Removed ground prong from harness, refitted with ground wire, and replaced.
Everything now works.
Thanks everyone for all of your valuable advice and posts.
