- Disconnect A/C Control Unit (ACCU) 3-pin connector, located under blower motor. Inspect connector and wiring for damage. Turn ignition on, A/C switch to second level, temperature control to maximum cooling and blower switch to high.
- Using a DVOM set to appropriate test function, inspect harness side of connector. See Fig 3
. Go to next step. If all test readings are as specified, replace A/C control unit. If readings are incorrect, repair circuit(s) as required.
- Terminal No. 1 (Green/Orange wire on Eclipse) is ACCU power supply when ignition switch is on, battery voltage should be present.
- Terminal No. 2 (Blue/Black wire) is A/C compressor relay. When ACCU has received signals from pressure and temperature sensors confirming A/C operation is okay, A/C switch is on, and blower motor switch is on, battery voltage should be present.
- Terminal No. 3 (Black wire) is A/C control unit ground. There should be zero volts at all times.
