Re: 2001 Mercury Sable A/C nightmare
Do the EATC self test the next time it happens and record the codes that are displayed. You may find something from this:
The Remote Climate Control (RCC) module self-test will not detect concerns associated with data link messages like engine coolant temperature or vehicle speed signals. A scan tool must be used to retrieve these concerns.
The RCC module self-test will detect concerns in the system control functions and will display hard Diagnostic Trouble Codes (DTCs) in addition to intermittent diagnostic trouble codes for concerns that occur during system operation. The vehicle interior temperature should be between 4°-38°C (40°-100°F) when carrying out the self-test. If the temperature is not within the specified range, false in-car temperature sensor DTCs will be displayed.
The self-test can be initiated at any time. Normal operation of the system stops when the self-test is activated.
To enter the self-test, press the OFF and floor buttons simultaneously and then press the AUTO button within two seconds . The display will show a dashed line in the center of the climate control display window of the integrated Control Panel (ICP) .
The test may run as long as 30 seconds . Record all DTCs displayed. The self-test is completed when 888 appears in the center of the climate control display window of the ICP.
If any DTCs appear during the self-test, refer to the RCC DTC INDEX. Carry out the diagnostic procedure given under ACTION TO TAKE for each DTC given. See: Diagnostic Trouble Code Descriptions\Remote Climate Control Module Diagnostic Trouble Code Index
If a condition exists but no DTCs appear during the self-test, refer to the SYMPTOM CHART condition: The EATC System is Inoperative, Intermittent or Incorrect Operation.See: Symptom Related Diagnostic Procedures
To exit the self-test and retain all intermittent DTCs, press the "-" (cooler) side of the TEMP button. The RCC module will exit the self-test and retain all intermittent DTCs.
To exit the self-test and clear all DTCs, press the front defrost button. All RCC module DTCs will be cleared.
Always exit the self-test before powering the system down (system turned off).
Intermittent DTCs will be deleted after 80 ignition switch ON cycles after the intermittent condition occurs.
