Concorde V6-3.2L VIN J (2000)
Cabin Temperature Sensor / Switch: Service and Repair
IN-CAR TEMPERATURE SENSOR REPLACEMENT
ATC In-Car Temperature Sensor
The In-car Temperature Sensor is part of the ATC Control Head and not a separate service part. If defective, the complete ATC head must be replaced.
The ATC In-Car Temperature Sensor is located in the Control Head. The Control Head must be removed for service to the sensor.
REMOVAL
Negative Battery Cable Remote Terminal
1. Open hood and disconnect the negative battery cable remote terminal from the remote battery post.
2. Remove snap-on center bezel which holds the ATC Control.
3. Disconnect the ATC Control from the vehicle wiring harness.
4. If the ATC in-car temperature sensor (fault 26) is verified to be bad, then the ATC control section of the assembly must be replaced. If the ATC
in-car sensor does not pass the paper test, then the problem may only be with the ATC In-Car Sensor Fan-Motor assembly.
5. Remove the fan-motor assembly from the ATC control with two screws located on the back of the ATC control.
6. Replace only the fan-motor assembly if control does not pass the paper test, but passes with no fault code 26 (bad thermistor).
NOTE: Retest control. If ATC control still fails the paper test, then replace the ATC control and the fan-motor assembly. The ATC Control must
be replaced if the part fails fault code 26 (after confirming proper wiring connections).
