Avalanche 4WD 8-cyl

  • 36,500 miles
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.
