2000 Grand Marquis: schematic..Cutout..quits..PCM (schematic)Sorry

This answer was rated:

2000 Grand Marquis, need A/C schematic and routing of HP Cutout switch.

See question 3s54y-2000-grand-marquis-a-c-quits-while-driving-on-highway

HP cutout switch has 2 sets of contacts (4 wires).
EATC schematic (055-3) only shows 1 set wired in serries with LP cutout/Cycling.

Can you shed any light on where the other set goes. Probably PCM (schematic)

Sorry, 10 yr old car, can't really see the color of the wires.

All the diagrams show it to be a 2 wire sensor, what is the build date of your car?
Customer: replied 7 years ago.


Build date is 12/99.


How about on the PCM diagrams?


I think I found just what you need.
