Since having the heater / ac fan speed control module replaced under a recall last fall, this summer I have had several situations where the A/C unit will turn to heat or, the A/C will go to defrost, defrost / feet, without moving the selector controls.

I own both a Chevy Silverado and Suburban 2005. Both vehicles will randomly start blowing hot air out the driver's side. I know at least 5 other people that have 2005 Chevy and their vehicle does the same thing. I tried working with the dealer and Chevy and both act like they never heard of the problem. Chevy refuses to acknowledge that this is a defected issue on their part and want over $1000 to fix the issue. Is there anyway you can get government motors to issue a recall?

The HVAC controls, air door actuator; part #89018365, failed on my truck one evening allowing only cold air to flow through the driver's side defroster/heater. Not only did I have cold air blowing all of the time on the driver's side of the truck but the windshield would fog up due to the cold air thus restricting my vision. This was not a good thing to happen while returning home one evening from another city. I looked on line and it appears Chevy has had a lot of problems with this plastic switch. I have never had this problem with other vehicles in over 40 years of driving. It is extremely difficult to fix. Chevy dealer wanted over $500 to repair plus $263.56 for the part! I had it done elsewhere for $510.30. Should there be a recall on this part" why does this part fail so frequently"

Air blows cold on driver side and extremely hot on drivers side with dual controls both set to cool. Seems to be a very common problem according to many people on the following website and unable to be fixed by dealers. autoforum.classifieds1000.com/Chevrolet-silverado_1500_pickup/dual_ac_blows_cold_air_on_passenger_but_hot_on_driver.
