    I have a 71 Challenger that came with factory AC. The heater/AC box has a couple of vacuum motors that direct the airflow differently for heat, AC, or defrost. Does anyone know anyone who sells replacement vacuum motors, or offers a rebuild service? My heater/AC box has the vacuum motors intact, but they do not work. I have talked to Classic Industries and Tony's Parts....they can not help me. Thanks.

    I have to say the one upgrade I did to my car and had no issues or regrets with, was swapping my factory ac over to a vintage air system. Clean and functional.

    I guess I got lucky as all mine worked. I bet the vacuum motors may not be E-body specific. Older trucks, vans, or other mopar cars might have the same ones.

    I have an entire box. I rebuilt before I swapped it all out. I checked the vacuum solenoids they worked then I can check them again this weekend with my pump I’d be willing to sell the complete suitcase has new heater core and pressure checked Evap. The thing takes up valuable room lmk if you’re interested.

    If you’re interested, I just checked all mine on the suitcase I rebuilt. All work and hold a vacuum. Can remove them and ship if you need to go used and don’t want the assembly?
