    What’s the voltage going to the compressor? With key on engine off, a/c on max? What are your low and high side pressures? Do you have power (12volts)going to high/low pressure switch? Is the connector going to high/low switch terminals spread, or pushed back?

    Are you asking for help, or is this a contest to see who can guess what you're working on?

    I guess an International (based off a fussy close up pic). Do I win?
