Solenoids

VACUUM ELECTRIC SOLENOID

The vacuum solenoid converts electrical signals from the heater A/C control microprocessor into vacuum commands which position the mode, A/C-defrost, and outside air valves in the air distributor. Vacuum is constantly applied to the module which distributes the vacuum to five solenoid-controlled valves on the module. When the heater A/C control signals the module to change an air distributor valve position, the associated solenoid energizes and vacuum is applied to the proper actuator.
