#212 of 292 Key Is Locked In Ignation And Car Refuses To Start I Can't Even Move The Ge
Nov 27, 2011 (5:07 pm)
I have a 2002 Chevy Trailblazer. I have been having problems with my driver side running light for the last 6 months or so. I get it fixed and it always dies out after two weeks. I want you to know this so you will understand there is a wiring issue. Yesterday while I was at a light, I turned the engine off, as I do when my reduce power light comes on, to reset it, I can not remember if I put it in park first, I do this this turning the engine off because of the fan assembly causing the reduce engine power to kick in and turning the car off usually re-sets it. Well unfortunately when I went to re-start the car, nothing, couldn't even turn the key, move my gear-shift, locked completely. A man stopped to help me jump my car, nothing, he then hooked the red jumper to the fuse box, I got power back again, battery gauge listed fine, key would turn, but the engine would not start, I got the clicking, and hum of fuel pump just would not turn over engine, when he removed the cable, locked again, nothing, I had to get the car towed, and I have no idea what to do now. The battery is less than 8 months old, replaced fuel pump less than a year ago, trannie has been replaced 2years ago, if that helps. I did get a blown fuse in the back seat fuse box the night before, the fuse sparked (Rear fog)when I tried to replace it so I just left it blank. Any suggestions would help I have spent all day researching, I can't afford too much, just got laid off, and lost my place, I am staying at a remote 2nd house of a friend, my car is all I got, please help, thanks!

If the low beams are inop try swapping the relays for the cooling fan into the low beam circuit. I have found that this is a common issue on GM's that use the same system as your trailblazer does. If you look under the hood on driver side of engine compartment you will ssee te fuse block. I belive its relay #45 that controls the cooling fan and relay #46 that controls the daytime running light module. Swap these to relays if the lights come on you know its the relay thats faulty. Keep in mind that you DO NOT want to leave the relays swaped becuase now your cooling fan will not work and engine couls over heat.

Sounds like you have way too many problems. Chances are its not all related to one issue. My advice to you....Get a new truck!!
#215 of 292 electrical problem, hatch door
Dec 01, 2011 (7:41 am)
When I have the hatch door open on my 2003 TB, I hear a constant clicking noise. This has been occurring for a few weeks, and lately I have intermittent electrical problems such as the rear wipers not working, and radio shuts off, windows do not operate, and all dash lights go on. Any one else experience this?

#217 of 292 Electrical problems?
Dec 07, 2011 (6:25 am)
Anyone aware of any electrical problems with the 2006 chevy trailblazer? I just replaced the battery 3 weeks ago because it would not start/crank/anything. This morning... same thing again! So frustrating. It ran without any problems yesterday, and all of the sudden, nothing. I can't have a non-reliable car... next time this happens, I'm selling it and buying a German car like I should have... all along...

Let me know when you find that trouble free German car, I'll consider one myself.
Anyway, how do you know the problem is the battery? Was the voltage checked?
#219 of 292 Electrical?
Dec 09, 2011 (3:14 pm)
I have an 03 LT Trailblazer, never had any major issues with it, bought it used and have been very happy......until last summer. I noticed that the left turn signal was real dim when not in use and if you tried to use it it would blink really fast... when the left turn signal was dim like that the air conditioner would not blow cold air......I'm not sure why but things went back to normal for a little while, then they started again and have escalated. The left door speaker and dash speaker won't work, only part of lights on the radio-heater console work, part of the light in my speedometer don't work, sometimes the cruise won't cooperate and today the windshield wipers just stopped and the lights would not come on.
We've been loyal Chevy owners for many years, my 3 month old 93 s 10 pickup sat in my yard went boom and burned, alternator shorted out, GM took responsibility and I got another truck. In my 95 I bought a new GMC Safari van and didn't get home with it, some sensor went out and I drove a loaner for a week......but I've stuck with 'em cos they've always fixed what went wrong, not now, nobody knows.......I need help with this please.

there are 4 studs sticking up in your fuse box under the hood, one of my had a little wiggle in it and when we tightened it up it has fixed the headlight problem right now. So try this maybe it can help you too.
#221 of 292 how do i replace my tail light wire harness??
Dec 12, 2011 (10:09 pm)
2003 trailblazer. Running light on passenger side went out while the brake light still worked, same bulb. I detatched the wire harness from the tail light circuit board to find the pins corroded and broken. I've got the replacement circuit board and wire harness, but have no clue how to remove the old harness or how to hook the new wires into the vehicle. in the new package there are five white wires and five small orangish tubes. Just moved to a new city, don't know anyone, and don't want to get pulled over for it AGAIN!! any suggestions??
