To aid in determining whether or not the electrical-vacuum, and refrigeration systems are operating properly, refer to the following:
1. Operation of the air conditioning modes and blower at all speeds with the mode lever in any position except "OFF" and engagement of the compressor clutch would indicate that the electrical circuits are operating properly.
2. The same "hand felt" temperature of the evaporator inlet pipe and the accumulator surface of an operating system would indicate a properly charged system.
2. Continue diagnostics with a Performance Test. System Performance Test
