I have a 2005 Ford Five Hundred with Automatic Climate Control.
the blower only blows on high and once turned on will not turn off either, I am thinking that it is the blower motor speed control, but i cant find any test to make sure before i buy a new one.
I tried to search but did not find anything for auto climate.
thanks for all your help
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
3. 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
4. If any DTCs appear during the self-test, record the #.
5. 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.
6. 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. If you exit by this method, your system will recalibrate the blend door.
If you get a code, I can give you the key for the codes. I do not have them handy but can get them.
The fan motor control is right by the fan, just under the glove box.
