Hvac failure routing hot air when a/c is on and vice versa, also routing to defroster and heater works erratically. *tr
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. *tr
