Test
NOTE:
- Before testing the motor, check for climate control DTCs - Refer to: How
to Troubleshoot the Climate
Control System, or How to Troubleshoot the Body Electrical. (With Climate
Control)
- Before testing the motor, check for HVAC control DTCs. (Without Climate
Control)
1. Outside Air Temperature Sensor - Test

- Dip the sensor in ice water, and measure the resistance. Then pour warm
water on
the sensor, and check for a change in resistance
- Compare the resistance reading between terminals No. 1 and No. 2 of the
outside
air temperature sensor with the specifications shown in the graph; the
resistance
should be within the specifications
- If the resistance is not as specified, replace the outside air
temperature sensor.

- Install the parts in the reverse order of removal, and note these items:
- Install the desiccant as quickly as possible to prevent the system
from absorbing moisture from
the air.
- If you are installing a new desiccant, add the appropriate
refrigerant oil for the A/C
compressor which installed to the vehicle.
- New O-rings should be used at each fitting. Prior to installation,
apply a thin coat of the same refrigerant oil used in the A/C
compressor. Be sure to use the correct O-rings for HFC-134a
(R-134a) to avoid leakage.
- Charge the system with the specified amount of R- 134a refrigerant.
