Vacuum/Electric Solenoid

The vacuum/electric solenoid contains the solenoid valves that control the mode valve actuators. There is one solenoid for each mode valve actuator. When the solenoids are de-energized, the valves vent the mode valve actuators, allowing the vacuum actuator to return to the vent position determined by a spring. Voltage is supplied through the HVAC fuse and circuit 41 (BRN) to the solenoid valves when the ignition switch is on.
