Mopar Parts & Services
Classic Auto Air can repair or replace the Heater Valve for your heater and the only important type of valves in an early model Mopar air conditioning system: Expansion Valve.
What does a heater valve do?
The heater control valve regulates, by opening or closing, the amount of hot water that enters the heater coil.
Why restore or replace your heater valve?
A good indication that your heater control valve is failing is if your air conditioning is functioning correctly and your system gauge readings are correct, but you’re getting heat or warm air out of the vents. This could be as a result of a failed heater control valve that will not shut off the flow of water to your heater coil. The heater control valve can also fail by leaking, or even by not opening and allowing water to flow into the heater coil in heat-mode.
Buy a new Heater Control Valve or let us restore yours!
Classic Auto Air carries new heater control valves, we have many NOS & NORS heater control valves. While we do have some of the most common heater coils, many are no longer available. In most cases, Classic Auto Air can re-core your original or we may have a NOS coil available. Please call or email for more information.
We offer many NOS & NORS heater control valves for Chrylser, Plymouth & Dodge vehicles and also restoration services for most lever-operated heater control valves. Call or email for more information!
What is an expansion valve?
The expansion valve is mounted at the evaporator inlet and regulates the refrigerant going into the evaporator.

We offer new direct replacement, NOS & NORS Mopar expansion valves. Please call or email!
Why replace or restore my expansion valve?
Most a/c technicians will automatically change out the expansion valve as it’s commonly a source of air conditioning failure. A good indication that your expansion valve has failed or is failing is a negative or high system gauge reading. This is either as a result of contaminants clogging the valve up or valve failure.
Because many valves are no longer made, Classic Auto Air offers testing and reconditioning services for your original. There is also a good chance that a NOS or NORS might be available. Please call or email!
Expansion valve reconditioning consists of:
- Flush clean internally
- Clean externally
- Re-plate, if originally plated.
