There's nothing more annoying than not having your truck's heater and/or A/C blend doors respond when you try to open/close them. These exact-replacement vacuum doors and actuators will fix that problem and restore driving comfort and HVAC operation.
Since many trucks have several different air door actuators, be sure to compare your motor to the ones shown to make sure you get the one you need. If you don't know which one needs to be replaced, please consult a qualified service technician.
