Owner was driving, attempted to turn up HVAC fan to higher speed but noticed that fan would not increase speed and stayed on the low speed. Then started to smell smoke. Pulled over, shut truck off but noticed HVAC blower fan was still running on low speed. Saw fire inside right side of dash. Fire originated inside right side of dash at location of blower motor and resistor components.

Anytime I turn the air on in my 2005 Chevy Avalanche it makes a high pitch screaming sound. I have had two blower motors installed and it is in need of a third. This sound is still present even after I have had the new motors installed. I have had one mechanic say their is a crack in the plenum box and it would take 11 1/2 hours to repair and cost $ 1700. This is the only quote I have had so far. I have had it at the dealership where I bought it and they never seem to find anything, then again they seldom do anything right.

I have a 2005 Chevrolet Avalanche that the driver side blows hot and the passenger blows cold sporadically. I have read that many people have had this same exact problem. I have only owned the vehicle a few months at it has happened approximately 4 times already. I will have to replace one of the actuators to repair. This should be a recall as it is a widespread problem.

HVAC failure routing hot air when A/C is on and vice versa, also routing to defroster and heater works erratically.
