Air Conditioning problem
2003 Chevy Trailblazer 6 cyl Two Wheel Drive Automatic

My trailblazer started acting up about 3 weeks ago when i would push the button to have the air blow higher it wouldnt switch i would have to keep messing with the button to get it to work. Now it does not blow out in the front at all the rear of the vehicle still blows great and is ice cold. I dont know wether the blower fan is bad or the actual switch. Can you please help me?

Working in same problem myself. Quit blowing on my way to the beach. Made for a fun ride...

Seems that these models have some major electrical issues. Blower is pretty easy to pull and check. Located beneath the glove box. Check relay in fuse box. I have had several suggest replacing the HVAC controls in the dash. I did that yesterday. Not the issue. I am contemplating getting some help.

Hopefully you have a bad blower. Easy to replace and about $65.
