Heating & Air Conditioning
The inability to turn on the windshield defroster may decrease the driver's visibility thereby increasing the risk of a crash.
The heating, ventilation, and air conditioning system is referred to as the HVAC system. These vehicles are being recalled because when starting the vehicle the HVAC system may not work, preventing the windshield from defrosting when necessary. This could adversely affect driver visibility and increasing the risk of a crash. Dealers will update the HVAC control module software to correct this concern.
General Motors will notify owners beginning December 6, 2013. If you don't receive notification and you feel you should, please contact your dealer for further instruction. They may ask for your vehicle identification number (VIN), so please have it handy when you call. The General Motors recall number is 13380.
