2003 Trailblazer LTZ AC issues
when starting vehicle the ac runs fine then after it warms up then all of a
sudden it stops blowing cold air and blows hot air. Looking for suggestions
into to what to look for. checked refrigerate and its full, compressor is
operating fine also, checked fuses and relays and they appear to be okay.
Wondering if you figured out the problem. I have an 04 trailblazer ls and it’s doing the same thing!
