The resistor pack should be to the left of the blower motor and screwed to the lower housing. Follow the leads attached to the motor and it should connect at the resistors.

Check the green/red wire on terminal number 10 of the MCC control panel for 12 volts with the engine running for at least 10 seconds and the ac on. Also check terminal number 8(red wire) with the engine running for 12 volts. This lead lets the mcc module know the engine is running and the module will supply power to the compressor clutch through the low pressure switch after the engine is running for approximately 10 seconds. Let me know what you find. John
