Test C: A/C Compressor Mode Control Test (Table 2):

C1 With engine running and Mode Selector in NORM, measure voltage at terminal 4 of the A/C Compressor Relay with a fused jumper connected across the terminals of the A/C Low Pressure Cut-Out Switch connector (disconnected).

^ If battery voltage is present, check for normal refrigerant charge. If the refrigerant charge is normal, replace the A/C Low Pressure Cut-Out Switch.

^ If battery voltage is not present, go to C2.

C2 Measure the voltage at terminal 4 of the A/C Compressor Relay with a fused jumper connected across the terminals of the A/C High Pressure Cut-Out Switch connector (disconnected).

^ If battery voltage is present, replace the A/C High Pressure Cut-Out Switch.

^ If battery voltage is not present, check the wiring between the switches back to the Heater And A/C Control Assembly (see schematic).
