A/C blend doors on some late-model GM and Jeep vehicles can crack where the door shaft connects to the actuator control, reducing heated air to the passenger compartment. AirSept’s A/C Blend Door Repair Tool allows users to replace the damaged section of the blend door shaft without removing the door from the HVAC or air conditioning unit, and without case disassembly. Traditional removal of the HVAC case and dashboard is a minimum eight-hour job. Using AirSept’s new Blend Door Repair Tool takes approximately two hours. There's no dash removal required, and no cutting into the HVAC case. This tool works with a standard or adjustable wrench.
