Replying to: senecio (Feb 03, 2008 5:05 pm) I also had electrical problems with my 03 EXT. I had the dash lights flicker, gage cluster package go on and off, all lights and indicators. My delaership replaced the ignition switch for $550. On the final test drive the issues appeared again, however the tech had my back seat folded up for access to the rear floor panel. He noticed that when he hit bumps the electrical issues started again. The seat was bouncing on the wire harness under the rear mat. This caused lose connections and intermittent issues. They rewired the harness on the rear floor, moved it to the side and put some extra padding on the floor to cover the worn harness. Repaid me on the labor part of the ignition switch. This was 6 months ago and everything seems OK. However my speed o meter motor just went out, not related, and I had to replace my cluster....this is a fault of the poor quality servo motors.   Now only issue is my driver seat is not working on the forward and reverse mode, making it tough for my wifr to drive. Any ideas on seat issue? Replies to this message: malibukp (Feb 20, 2008 10:09 am) gonzofulda (Dec 01, 2008 11:55 am) tamesa (Dec 01, 2008 12:59 pm) malibukp (Jan 03, 2009 12:07 am)

Replying to: woc (Feb 20, 2008 6:11 am) Wow, you got reamed by the dealership!! I had my ignition switch replaced by Goodyear for 80.00, including parts and labor! AND, I found a bulletin from GM stating that they were having problems with ignition switches in 17 different models of their cars, so I called GM headquarters to complain that there was not a recall. They repaid me for the part, 43.00, so I just had to pay 50 for labor. They stated that had I taken it to a dealership they would have repaid me for the labor as well.

Replying to: robbyr (Feb 17, 2008 4:20 pm) Thanks Robby! I had a crazy issue happen yesterday. I was sitting in my car using the cigarette lighter for power for my computer. Didn't have the car running and when I went to start up heard nothing but a clicking noise. I thought that maybe I had drained the battery. Attemted to get a jump and nothing happened. However, now the battery went totally dead. The key became stuck in the ignition (still in there) and power locks and remotes wouldn't work. So I thought the battery is totally dead now. Car was making funny noises and it would slightly power up(electrical system driver memory dash lights etc). But now nothing works.   However, the one thing that I didn't notice is that I opened my hatch yesterday to get something out of it. Interestingly enough this could be the cause. Because the second time I opened the hatch to get the jumper cables out (problems got worse). I didn't make the connection. I am going to have the car towed to the dealer(provided no one has stolen it since I had to leave the key in the freaking ignition overnight at my office) and I will have them start with this problem first. Will post again if this in fact was the problem. Thanks again as I was totally confused as to where to start. Battery, ignition, starter(had that replaced last year) etc...

#38 of 104 Ignition Switch shorting out by gabby1729 Feb 28, 2008 (6:58 am)
Hello everyone. I am having similar yet different problems with my '06 Trailblazer and I'm curious if anyone else has had them too? My truck is currently in the shop for 4th time in 6months for problems. This is the 3rd time the ignition switch has gone out. So the truck has power but wont start. It has been in the shop for a short in the gas gauge, so the analog gauge would not register and the digital gauge was not accurate. That problem caused me to run out of gas, luckily I was close to the gas station! Yesterday the "service stabilitrak" light came on, then it went off. One hour later the truck died and would not start, it had power but would not start. It definately has electric gremlins. The dealership does not think these 2 problems are interlinked, I disagree but the are the "experts". My back hatch latch (say that 3 times fast) is malfunctioning too. When I open the hatch it stays locked, so when I go to close the hatch it hits the locking bar. I have to hold up the handle and manually push the locking bar open so it can then latch around the T-bar at closure. I think it is a BIG lemon!!?? I am just waiting for it to blow up in my garage. Help! It is scary that these problems keep happening. We travel a lot and I am the mom of the family, so I always have kids...it is getting really inconvenient to have this thing towed to the shop every 2 months! Thanks for your time!

#41 of 104 Re: Draining battery down [malibukp] by baddbone Jun 20, 2008 (1:00 pm)
Replying to: malibukp (Feb 07, 2008 5:43 pm) Your problem is the battery in your remote on the key. It happened on my wife's Envoy. No one at GM knew what it meant. My brother in law, a former GM mechanic mentioned the possinbility of being the bettery in the key's remote. That's the battery they are talking about. It worked after she changed the battery. Message cleared up. Replies to this message: malibukp (Jan 03, 2009 12:20 am)
#42 of 104 01 Trailblazer Electrical/Turn Signal Problems by ticadoo Jul 07, 2008 (7:53 am)
My trailblazer only has 63,000 miles on it, but I've had tons of problems! The latest problem is that all of a sudden my left turn signal started "clicking/flashing" really fast. Now, sometimes it works and sometimes it doesn't. Also, when I put truck into park, all doors unlock except driver's door. It sounds like some type of electrical problem???? Any help would be greatly appreciated!! Replies to this message: graymc21 (Aug 27, 2008 8:47 am) jrcrane (Jan 31, 2009 11:59 am) ticadoo (Feb 02, 2009 6:37 am)

Replying to: ticadoo (Jul 07, 2008 7:53 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?
