Look next to the blower. You can remove the panel under the passenger side. Go through the glove box and move it down out of the way to access the electrical connector. Then remove two bolts and the electrical connector.

All warning lights flashing on dash of my 2002 chevy trailblazer. Runs fine all gagues go dark and turn back on every now and then. Also the gagues all go to the right or stick half way like I am idling at 5000 and going at a speed of 60mph when I am sitting still. I am thinking it has something to do with my computer because the rest of the truck is working just fine.
SOURCE: my 2004 chevy trailblazer is making a loud noise
it's a very good possibility. the fan clutches in trailblazers are a common issue
SOURCE: 2004 Chevy Trailblazer idles rough.
If it has not pulled any codes (idiot light). Clean your throttle body, and change your spark plugs with A/C Delcos #41-103, most other brands will cause rough idle like Autolites and Bosch. This would be a cheap way to fix this problem.
If by chance you have just recently changed the battery or had the battery unhooked. Let me know, it's an easier fix that costs virtually nothing.
