problem #1

Nov 022007

Avalanche 1500 5.3L V8

  • Automatic transmission
  • 25,000 miles

I can only get hot air out of the passenger side of the heater outlets. This temperature seems to be controlled by the passenger side temperature slide control. The driver side puts out only cold air even when the driver's side temperature slide control is adjusted for full heat. I suspect an air baffle in the air duct is stuck in the cold position.
