I have scoured this site for anyone with similar issues but sounds like I may be a pioneer to this one. I have an 06 trailblazer ls 4.2 4wd and have just finished putting a used motor in it but have yet to get it successfully started. I originally tried using the pcm that was on that motor and...

My trailblazer randomly would not start one morning. Key on, dash lights up, radio works, etc. Go to crank engine and the whole car goes dead. Battery is holding well over 12 volts, so thats no problem. I replaced the ignition switch yesterday, still the same symptoms. Thinking it may be a...

Hey all! My 03 Envoy just died on me today :( .

I wasn't really...

I have owned my 2007 TBSS since it was brand new. Due to the famous engine oil pickup issue it sat for 3 years with 77,000 miles on it. I replaced the engine with a factory re build in October 2016. Its now April 2017 with about 88,000 miles on it and the strangest thing happened. I was...

First time poster, hoping to become a regular around here. I've got a 2006 Trailblazer ext 4x4 with the 5.3 V8 that has suddenly decided not to attempt to spin the starter when the key is moved to the start location. Battery charge and grounds are fine. With the hood open and the main fuse block...

I am wanting to install some LED lights under my dash and seats. I would like them to come on when I turn my headlights/dash lights on. I am also replacing the factory stereo. Could I connect the hot on the LED lights to the illumination wire on the radio harness to make them power on when I...

Hey Everyone, I'm new here and have an issue I'd like to get some better insight on. I have a 2004 Envoy, I6 with a continuing misfire P0300 issue. 150,000+ miles. Several weeks ago, the engine started to misfire (blinking check engine light, running terribly). I put in AC Delco plugs about...

As the title would imply, I did a reset on my TCCM because I cant get my 04 envoy to come out of 2 wheel drive after having replaced the transmission. I did this by unhooking the battery, and unplugging the TCCM (hooking back up in reverse order) as a mechanic friend told me to do. However when...

I have been searching the forums on a few sites for a few days trying to find a clue as to what's happening with my TBSS. I promise I'm not the guy that just posts because he's too lazy to look. (I bet after this someone will find the thread I was looking for and call me out, haha) Alright...

My troubles all started after I brought my 02 trailblazer to AutoZone for them to diagnose why my check engine light was on. The result was that my fan wasn't running as optimally as usual, and he said, "Your fan is still working and your SUV isn't overheating so I wouldn't worry about it too...

Hello everyone. This is my first time posting anything here and I hope that someone can help me. My 2008 TB died on me while driving down the road like it was out of gas. It cranked back up a few times after that but died after about 10 seconds. Now it will not turn over at all. When I have the...

Just thought I'd share this. Hope it helps some folks before they run out and buy an ignition switch or shifter assy. Symptoms: Key stuck in ignition, won't turn past ACC position. Shifter moves freely without pressing the brake pedal. I took the shifter boot off and saw that the locking...

I have a 05 Envoy. I have been having problems with the heater, and now it has seem to move to more of the electrical in the truck. In the last week and a half I have had to use a battery charger twice to start the truck. Once I do that and give my dad a ride to work the battery will stay...
