Hey guys/girls,

My 02 Trailblazer will only blow air on settings 3,4,5 and not on 1 or 2. Also the driver side temp control does not light up but the passenger side will. Any Ideas? I already replaced the entire Climate control Unit that i found on ebay with no luck.

When you say that it's doesn't blow, you mean not at all? Nothing? 1 and 2 don't do much on my 02 Trailblazer, but they do something.

the blower does not engage until put on setting 3 4 5. wont blow at all on one or two. it all of a sudden stopped.
