YOU COULD HAVE OPEN OR SHORT IN THE BLACK YELLOW WIRE GOING TO AC COMPRESSOR CYCLING PRESSURE SWITCH. CHECK FOR A SHORT OR OPEN IN RED YELLOW WIRES AT THE AC PRESSURE CUTOFF SWITCH. USE VOLT METER AND CHECK FOR VOLTAGE AT BOTH SWITCHES. PROBLEM COULD BE IN THE EATC MODULE THAT SEND POWER TO PURPLE WIRE THAT FEEDS THE AC PRESSURE CUTOFF SWITCH AND AC CLUTCH CYCLING PRESSURE SWITCH THEN FEEDS THE AC COMPRESSOR CLUTCH SOLENOID.

AC not working


Apparently the local shop did not trace the clutch wiring back to the power source to find out why no voltage was getting through.

Relay 1 passenger fuse box


Does the heater work ? blower motor pushes air out of the vent's ? A/C compressor doesn't engage ? I'm try to figure out what you have going on there . completely dead on dash panel ? Two fuse in the central junction box F2.14 10 amp an F2.20 10 amp these power the climate control panel . Relay one has nothing to do with it . If the fuse's are good you need a new control panel .

Your AC mechanic is a know nada POS. Your AC is not working because the clutch is not being properly energized so as to turn the compressor which as you indicated is working and fully charged. Either the climate control head you just got is no good, ditto for the low pressure cut off switch, thermostat.. Best thing to do is get a hold of someone who has the AC schematic and can check out all of the electrical components in the way of getting power to the clutch!

The PCM - powertrain control module energizes the A/C clutch relay . Don't know what this other guy's talking about ? No VCRM on your vehicle .Engine computer controls it . PCM . Now if the climate control , heater / A/C is not blowing out of the vent's it's probably the heater blower control module . If you had it to a shop what did they say was wrong ?
