Inspection

1. Ignition "OFF"
2. Disconnect evaporator temperature sensor.
3. Using the multi-tester, Measure resistance between terminal "1" and "2" of evaporator temperature sensor.




[Specification]





4. If the measured resistance is not specification, substitute with a known-good evaporator temperature sensor and check for proper operation.
5. If the problem is corrected, replace the evaporator temperature sensor.

Replacement

1. Disconnect the negative (-) battery terminal.
2. Remove the extenser cover (A).




3. Disconnect the evaporator sensor connector (A).
4. Remove the evaporator temperature sensor (B), by pulling it after rotating 90° in a counter clock wise direction.





CAUTION:
Take care that evaporator core pins are not bent.

5. Installation is the reverse order of removal.
