Welcome to Trailblazerclub.com, a site that I hope will be used as a tool to expand the enjoyment of being a Chevy Trailblazer / GMC Envoy enthusiast.

Feel free to jump in, ask questions, give answers, discuss how-to-fixes or provide any other information that you think is relevant to the community as a whole.

We know that heating and cooling systems isn't the most glamourous part of your Trailblazer/Envoy, but when there is an issue with them, life isn't as much fun.
