CarComplaints.com Notes: The Trailblazer emerged from an "upscale trim line" of the Blazer, but there's nothing upscale about its transmission problems or its wonky, unpredictable headlights.
Has anyone else had the drivers door switch go bad where only the drivers door window doesn't work, I put the scan tool on and it says the switch is working, and I have hot wired the wiring to the regulator and that works, but when you plug the two together there is nothing. I'd buy a switch but the scan tool says it works, so it appears to be wasting $250.
Window regulators have gone bad in both back windows but can't find parts locally. However, been quoted $100 a piece plus $55.00 each labor to put in, shop tells me 8th one they've done. Should be recalled if you haven't had this problem yet just wait it's coming. I already replaced the driver window one a year ago coat me $120 for that one.
I think GM has a number of problems in their multiplexing modules for the CAN communication between modules. The truck has never worked right from the beginning on the electrical operations as various "quirks" have occurred. As a design engineer in electrical CAN systems, I have noticed this over the past 2 years with the truck.
GM should step up to the plate and address the problem instead of burying with the customer and having customer absorb costs of their development. Other people must have the same problem!
Passenger window and power door lock will not work. all other 3 windows and power door locks work ok. harness plug between door and truck frame appears to be in good condition.
