Dash warning lights

i have seen so many trailblazers with this same problem and more a/c will go out speed gauge will go out ( use you're gps, for speed gauge) rear window wiper, tail lights and possibly more i hate to be the one to break it to you i hope urone of the few it doesnt happen to. and the biggest problem is have not a mechanic yet thats able to explain or completely rid the problem.

Yes I really hope I am one of the few but with my luck, all of the rest will happen tomorrow

does it have the stock radio? if not the radio could be the issue as the can communication goes through it.

Yes it does have the stock radio in it

Here are some recalls on that vehicle that might interest you. http://www.motortrend.com/cars/2006/chevrolet/trailblazer/recalls/

Thank you, I just checked my VIN# on the GM site and there is an active recall, it is a drivers door control module

That's the recall about a circuit board and a potential fire issue if it shorts out. Would not wait to long before you get it fixed.

Yeah I'm not gonna wait around to find out, gonna call the dealership tomorrow and see if it has been fixed or not

That's good. You know it's serious when in the recall wording they ask owners to park outside till a remedy fix is made. Good luck. Hope you can get it fixed.

Thanks and I hope I do too

From what I have read possibly bad abs module. Only repair I have found is to replace the module. This is for an 06 but might also pertain to yours. http://www.gm-trucks.com/forums/topic/118988-c0550-help/

My abs light is own engine light on and looks like traction lights on too

Mine did it too...easy fix...just replace the ignition switch...not the switch the key goes in but behind dash under the steering column

What does this light mean

Anyone know what that light means?

Why did I buy a chevy

Cause it's better than a Ford

This is what mine does 2003 Chevy Trailblazer

Did you find out what the problem was? I just ran into the same problem
