Remove the in-car temperature sensor (see page 21-117). 2. Measure the resistance between the No. 1 and No. 2 terminals of the in-car temperature sensor. Check for a change in resistance by heating or cooling the sensor with a hair drier. • Without Navigation System: Go to step 3. Replace the in-car temperature sensor. 3. Disconnect climate control unit connector B (20P). 4. Check for continuity between the No. 16 terminal of climate control unit connector B (20P) and the No. Go to step 5. Repair open in the wire between the climate control unit and the in-car temperature sensor. 5.
