trailblazer electrical issues

[jlee003]

Got a wierd one here, The radio keeps chaniging which speakers will work. sometimes a front one, some times a rear one. I would replace the radio if that was the only electrical problem. but sometimes when i start the car up, the stabilitrac warning and 4wd maint lights come on. If i drive for a little bit and then restart the car the lights go off. also, the drivers side window is very slow to come back up occasionally. when the lights are on, i can pull no tc's. it is just the lights. i have checked all the fuses and harneses for shorts or loose connections. Kinda at a loss here. anyone else with a tb have a similar issue?

This is interesting. I have a 2008 Chevy Trailblazer with similar issues. My radio goes in and out and my stabilitrak lights flash on and off while driving. I have replaced my fuses and traced through my wiring harness looking for any sort of ground. Nothing... Also my instrument panel has become noticeably hot to the touch. My buddy just bought a 2009 and is having this same heat / electrical issues. WTF is this?! I feel like my TB is gunna catch fire! Let me know of any progress you have made...

i double checked every harness i could find and no luck. there is no affect to the drive-ability and i haven't noticed the cluster heating up (haven't checked honestly) i am about to have to take it up to the dealership and see if they have any info on it.
