Air Door Actuator Gear

Were correcting another common issue with your Impala, Corvette, Gran Prix, Allure, Lacrosse, XLR, Monte Carlo, and other GM models. The air door actuator which controls the HVAC flaps within the dash due to a cheap plastic gear which drives the flap actuator. When this gear chips, you don't get proper HVAC ventilation.
