okay, ready? power comes from the A/C button through the Evaporator Temp. Regulator [inside the car on the L/S of the 'heater box'], [5 wire connector]. Power in is the green/yellow wire. Power out of it to the HIgh Press. Switch is the black......black/white wire. From the High Press. Switch on the rec/dryer it goes to the Compressor Clutch. Check for B+ @ the High Pr. Swt. 1st with the system on. IF 0 volts, go to the Evap. Temp Reg. checking power in then power out. there's a core temp sensor involved but the usual failure is the contacts of the Evap. Temp. Reg...have fun ! !
