So, long time lurker first time poster. I found out about this site while trying to help my grandfather with his 04 trailblazer and everything I have seen on here has been so helpful. Some of it was so crazy to find anywhere else but you guys had it covered (Special thanks to Mooseman for posting the trailblazer service manuals!)! Well amy grandfather has had his tb for about 2 years, and I liked it so much that me and my wife have now purchased one for ourselves. A 2003 trailblazer ls. I really just wanted to take a minute and thank you guys for all the information you make available, and for just being awesome!
