Control Module HVAC: Description and Operation
A/C Programmer/Solenoid Valve Assembly
A/C Vacuum Solenoid Module
The vacuum solenoid module converts electrical signals from the A/C control head into vacuum signals. These vacuum signals position the mode, the
A/C defrost, and the outside air valves in the air distributor. The vacuum is constantly applied to the module, which distributes the vacuum to four
solenoid-controlled valves in the module. When the A/C control signals the module to change an air distributor valve position, the associated solenoid
energizes and the vacuum is applied to the proper actuator.
