Crown Victoria V8-4.6L SOHC VIN 6 (1996)
Refrigerant Containment/Fan Function Switch (dual function).
For refrigerant containment control, the normally closed high pressure contacts open at a predetermined A/C head pressure. This turns off the A/C
by opening the A/C demand circuit, preventing the A/C pressure from rising to a level that would open the A/C High Pressure Relief Valve.
For fan function control, the normally open medium pressure contacts close at a predetermined A/C head pressure. This grounds the ACPSW
circuit input to the PCM. The PCM will then turn on the high speed fan to help reduce the pressure.
