i have only had this trailblazer for 6 days not even a week. brand new 2003 LS and the a/c isnt working. it doesnt blow out cold air. i am so pissed off its a brand new suv. im going to the dealership on monday to see what they are going to do (this happened sat at night) but i am so pissed i dont even want this suv anymore

I had the same problem with my 2003 LS model. I took it to the dealer and they replaced a sensor. I understand that many of the '03 models had this same problem. Don't give up yet.

It happened to my 2003 too, about ten days into ownership. They fixed it, and it's been fine. I wish that was the only problem I've had with this car. Back in for three different problems in the first six months.
