I have a 2003 4.2l I6 LS Trailblazer with over 186K Miles. Whenever I engage the rear window defroster it shorts out my power windows and locks intermittently almost like a timer every few seconds it shorts out everything. I have gotten by just not using the rear defroster but I am about to do...

OK, my 04 Envoy IL-6 is misbehaving.. When I get on the gas, it seems to hesitate a bit, then as I press harded, it takes off somewhat but then up around 6k rpm, it hesitates again and then shifts hard into the next gear.. It almost feels like it's starved for fuel? Like it's fighting itself...

Hello and thanks for being here. I joined last month and this is my first post. Bought my 06 Envoy XL last year and it needs a new (used or salavge) panel for the front seat power controls. I also need a center console cover. I think the person who had my truck before me was a little heavier...

After getting the 02 engine swapped with an 06, Ive been noticing on and off weriod screech noises on the engine. The Serp belt was already replaced just to let you know. My friend thinks its has something to do with the alternator since the serp belt is a little off aligned with the idle...

I was curious to see if anyone had any experience adding power mirrors to a base model with no power mirrors? I have an 04 Envoy XL and had been itching to add them but was unsure of what is required. I have heard that the harness has the pigtails for adding them but never looked myself. If...

How's everyone doing? I've read 90% of the posts within this section and have a question about a Sticky Post (Installing an Amplifier) and comments made by others advising against what's documented in the Sticky. If the majority users who have commented on adding an amp advise against using...
