Check for continuity between the No. 8 terminal of climate control unit connector B (22P) and the No. 2 terminal of the outside air temperature sensor 2P connector. CLIMATE CONTROL UNIT CONNECTOR B (22P) Wire side of female terminals OUTSIDE AIR TEMPERATURE SENSOR 2P CONNECTOR Wire side of female terminals Is there continuity? YES - Go to step 5. NO - Repair open in the wire between the climate control unit and the outside air temperature sensor. Disconnect climate control unit connector A (14P).

Check for continuity between the No. 2 terminal of climate control unit connector A (14P) and the No. 1 terminal of the outside air temperature sensor 2P connector. CLIMATE CONTROL UNIT CONNECTOR A (14P) Wire side of female terminals OUTSIDE AIR TEMPERATURE SENSOR 2P CONNECTOR Wire side of female terminals Is there continuity? YES - Check for loose wires or poor connections at climate control unit connectors A (14P) and B (22P) and at the outside air temperature sensor 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 open in the wire between the climate control unit and the outside air temperature sensor.
