#43 of 52 Re: 01 Trailblazer Electrical/Turn Signal Problems [ticadoo] by graymc21 Aug 27, 2008 (9:47 am)
Replying to: ticadoo (Jul 07, 2008 8:53 am) My 2005 Trailblazer head lights flicker at night for some odd reason, I have no clue why and the dealership can not seem to reenact it. I have complained to Chevy and it is currently in the shop for a "certified" report to give to GM. The battery dial also moves when the lights flicker. An suggestion on where to go from here?

My head lights have been flickering at night along with the battery dial in the dash board. I took it under warranty to have it looked at and they could not repeat it. I currently have a complaint into GM and I am taking it back in for them to do a "certified" test. I am not to sure where to go from here. Any suggestions/thoughts?
#46 of 52 2004 Trailblazer, Named Christine! by tamesa Sep 14, 2008 (3:46 pm)
My Christine has 91k for mileage and other than a few small issues, no complaints until last Friday after an oil change. The service engine light was on but I thought it was because I did not tighten the gas cap enough.   Then I had to get gas, that is when all the fun started. All the dash lights came on, the only gauges that were working is the speedometer and the tachometer. The gas, oil, temp and battery gauges are dead, the blower works, the a/c doesn't, the locks do not work, the cigarrette lighter does work, the front windows do not work, the power seat does work. The radio does not work.   I read that it could be a relay and i changed several of them and that is not the issue..I am guessing ignition switch again?
#47 of 52 Re: Electrical problems FINALLY FIXED!!! Thanks GM!! Not. [jeffhas] by amywilson Sep 14, 2008 (9:52 pm)
Replying to: jeffhas (Feb 26, 2008 12:47 am) This is the same thing happening to my 04 right now. I've only had it for a few months and about a month back I went out to start it up and it was dead. It was fairly new so I figured the kids had been playing in it and just left some lights on or something. Got it jumped and had the battery tested at AutoZone and it was all good. Haven't had any problems until just today. The car hasn't moved since Friday afternoon and my son was just in it one time and I doublechecked to make sure all the lights were off..etc. I try and go to the store and the battery is dead and now my key is stuck in the ignition. Once again, nothing was left on and the doors were all shut. I also have some lights come on like the service 4WD and service engine. I go to have them checked out and they go off. What is going on with this car?
#48 of 52 Electrical Problems? Engine cut Off!! by ticadoo Sep 19, 2008 (8:24 am)
OK. I need some advice. I was waiting in a turning lane...my 03 Chevrolet Trailblazer running...went to take off and the engine had cut off on me. Could this be electrical problems? It has done it once before...a couple of months ago and mechanic could not find a problem....it just turned 67,000 miles!!! Replies to this message: tamesa (Sep 19, 2008 9:06 am)

Replying to: ticadoo (Sep 19, 2008 8:24 am) The mechanic bless his heart, had a late night at the shop last night just to diagnose what I thought was either an ignition switch or alternator. As it turns out it was a Power Train Control Module that was not allowing the computers to communicate with each other.   So he was able to find a used one and will install it, but it needs to go to a dealer and have it programmed.
#51 of 52 Driver's seat does not work after battery change by cliff15 Oct 01, 2008 (6:59 pm)
Changed the battery today in my 2004 Trailblazer and now the front seat is all the way forward and does not work. Move any lever on side of seat and hear clicking noise from dash. Any suggestions?
#52 of 52 Wont start by jerry94 Oct 05, 2008 (12:13 pm)
Bought a 2002 trailblazer in Feb of this year.High freeway miles but ran fine.Wife called me about a month ago from our bank saying the battery was dead. I went a jumped the battery,but start up was a little hard for the next few days. I figured the battery was about gone, so I bought a new one and installed it.Started fine for the next couple of days. Was going out of town on a business trip,and when I was checking out fluids ,tires ,etc, noticed a nail in one tire.Took it down to the tire shop, and when the kid got in to take it in the bay,it wouldnt start,no clicking,no nothing.He jumped it and it started. After the tire was fixed,the same thing,and a jump again. Got it home turned it off and nothing again.I took our other vechile on my trip. When I got back I tried to jump it again,and the key jamed in the ignition. We had it towed to a shop of one of my employees husbands place and he replaced the lock,started it and stoped it for a few days,and only found a battery cable under the motor a little loose. We took it on a trip to Ca. {we live in Utah} to visit a friend. Th 2nd day there, I went to start it and dead again. My friend jumped it and we had no trouble for the next few days,and on our trip back no problems. Got back to Utah, drove around a couple of days. Went to get in to go to work after our little vacation, and dead again. It wont even jump now. Battery shows a charge,.I thinking a loose cable again as I cant even get any noise when I try to start it. The fellow that replaced the switch said the alternator/starter checked good, but he has limited testing equiptment.I have limited funds for repair, so the blazer has sit in the driveway for 2 weeks. HELP
