A/C MG Relay

The A/C MG relay is provided a power feed from the switch side of the heater relay when the ignition switch is ON and blower speed selector switch is in any position except OFF. The A/C compressor control module supplies a ground to the coil side of the relay in response to an A/C request and appropriate system conditions. Voltage is supplied to the compressor clutch when the A/C MG relay is energized. By energizing and de-energizing this relay, the A/C compressor control module is capable of controlling air conditioning system operation. When the A/C MG relay is energized, voltage is also supplied to the fan no. 3 relay which, when energized, is connected into the main and auxiliary fan motor circuit and is responsible for initiating main and auxiliary fan motor operation in series circuit form during A/C operation.
