2004 Chevrolet Avalanche Owner Comments

problem #4

May 012015

Avalanche LS 5.3L V8

  • Automatic transmission
  • 74,000 miles


Starting in around April I turned the AC on and it worked fine. Then a few days later it would start blowing hot. You could kill the motor and then restart it and the ac would blow cold again. This went on for a couple months and now it just blows hot all the time. I've checked the compressor, fuses, bought a new control panel, changed the high and low pressure switches and it is still not working. Also checked freon and it is full. I had it hooked to a computer and the only code that was showing was a bad blender actuator.

This truck has more problems for a 2004 than I've ever 2004 Avalanche A/C doesn't work. Try turning the vehicle off and then back on; the A/C may or may not work then.
