The 3L has a low pressure cut out switch on the compressor and a high pressure right on the line next to the compressor (or vice versa!). I think there must be a relay used between the button on the dash and the compressor clutch itself. Anybody out there have a schematic or know the system well?? -Jason

Hello, this is my first post EVER to the tc forum! I have a 1991 tc 3.0L. The air conditioning clutch is not getting power (12 volts), though the switch on the dash works and supplies 12V out when depressed. I am thinking there must be a relay in addition to the pressure switches on the compressor as in most ac set-ups. Does anyone know if there is, in fact, an a/c clutch relay, and where it is on the car? Even better, if someone can scan a schematic for me to use in trouble shooting, that would be fantastic. Thank you, -Jason Chicago, IL
