Power/Vacuum Module (PVM)

The PVM receives logic signals from the computer. It then controls the vacuum to the water valve, outside air recirculation, floor-A/C bi-level and defrost vacuum actuators. The PVM also supplies varied voltage to the blower motor and battery voltage to the A/C compressor clutch. The PVM is made up of two modules; the [1][2]power module and the vacuum module. Each is serviced separately.
