Evaporator Temperature Sensor / Switch: Service and Repair

CAUTION:
- All SRS wire harnesses are covered with yellow insulation. Before you disconnect any part of an SRS wire harness, disconnect the airbag connectors.
- Whenever the ignition switch is ON (II), or has been turned OFF for less than three minutes, be careful not to bump the SRS unit; the airbags could accidentally deploy and cause damage or injuries.
- For additional precautions, refer to Air Bags and Seat Belts.

1. Recover the refrigerant with a Recovery/Recycling/Charging System.





2. Disconnect the receiver line and the suction line from the evaporator.

NOTE: Plug or cap the lines immediately after disconnecting to avoid moisture and dust contamination into the system.

3. Remove the glove box.
4. Remove the glove box frame.





5. Disconnect the connector from the A/C thermostat.
Remove the four self-tapping screws, two mounting nuts and the mounting bolt.
Disconnect the drain hose, then remove the evaporator.





6. Pull out the A/C thermostat sensor from the evaporator fins.
7. Install in the reverse order of removal. Make note of the following items.
- Install the A/C thermostat sensor to its original location.
- If you're installing a new evaporator, add refrigerant oil (Sanden SP-10, Part No. 38899-P13-A01).
- Replace the 0-rings with new ones at each fitting, and apply a thin coat refrigerant oil before installing them.

NOTE: Be sure to use the right 0-rings for HFC 134a (R-134a) to avoid leakage.

- Apply sealant to the grommets.
- Make sure that there is no air leakage.
- Charge the system, and test its performance.
