9. Measure the voltage between the No. 24 terminal of the climate control unit 30P connector and body ground.
Is there battery voltage?
YES - Go to step 10.
NO - Repair open in the wire between the climate control unit and the A/C pressure switch.
10. Turn the ignition switch OFF.
11. Measure the resistance between the No. 2 and No. 5 terminals of the climate control unit 30P connector.
Is the resistance less than 24 kOhm?
YES - Check for loose wires or poor connections at the climate control unit 30P connector and at the A/C pressure switch 2P connector. If the
connections are good, substitute a known-good climate control unit, and recheck. If the symptom/indication goes away, replace the original climate
control unit.
NO - Repair cause of high resistance in the evaporator temperature circuit.
12. Make sure the A/C switch is OFF.
13. Measure the voltage between the No. 9 terminal of under-dash fuse/relay box connector F (12P) and body ground with the under-dash fuse/relay
box connectors connected.
Is there battery voltage?
