When I received my truck back from the dealership, the a/c blower was not working, The dealership told me that the parts are not covered under my extended ford warranty. I have a lariat that has the dual zone control module, the module still works (still lights up) just the a/c isn't blowing. anyone have any ideas as what the problem could be?

 

I should add the truck was in for warranty repairs unrelated to the a/c system, aforementioned repairs required that the cab be removed to completed repairs. ford diesel tech stated that he checked all the connections to the a/c system to make sure he didn't accidentally disconnect something and that everything was connected like it should have been. The service manager stated that the problem could be a resistor on the blower motor or the A?C control module neither are covered in the ESP.

 

If you find out let me know. That is my one gremlin for my truck. I will drive along and the blower will stop blowing. The dual climate control lights up but nothing blowing. If i adjust the fan the display changes but still not blower.

Mine either kicks back on and if not then I pull over and shut the vehicle off and restart and then it works again. Dealer replace the eatc 3 times before the 36k mile ran out. It has started to do it again.

 

Mine does the same thing but doesn't blow no matter what.

 

Anyone??

 

Come to think of it you should check the blower motor relay. take it out and put it back in

 

I'm offshore ill check it when i get in where is it located?

 

There is a way to check the EATC and if there are codes it would show up. If no codes then trouble shooting it would be the next step

Electronic Automatic Temperature Control (EATC) Module On-Demand Self Test

The Electronic Automatic Temperature Control (EATC) Module On-Demand Self Test will retrieve on-demand (hard fault) DTCs only, it will not retrieve continuous DTCs. Continuous DTCs can be cleared when exiting the Electronic Automatic Temperature Control (EATC) Module On-Demand Self Test. Make sure to retrieve continuous DTCs by carrying out the Electronic Automatic Temperature Control (EATC) Module — Retrieve Continuous DTCs procedure before clearing any continuous DTCs.

The Electronic Automatic Temperature Control (EATC) Module On-Demand 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 Electronic Automatic Temperature Control (EATC) Module On-Demand Self Test will detect concerns in the system control functions and will display on-demand (hard fault) DTCs for concerns that are present during the self-test. The vehicle interior temperature should be between 4°C-38°C (40°F-100°F) when carrying out the self-test. If the temperatures are not within the specified ranges, false DTCs may be displayed.
The self-test can be initiated after cycling the ignition switch from OFF to ON. Normal operation of the climate control system stops when the self-test is activated.
To enter the self-test, press the OFF and DEFROST buttons simultaneously and release, then press the AUTO button within 2 seconds. The display will show a flashing blower icon for 20 seconds, after which all vacuum fluorescent segments will be displayed if there are no on-demand DTCs present. If DTCs are present, the EATC module will display "00 00" and then on-demand DTCs. Record all DTCs displayed.
If any DTCs appear during the self-test, carry out the diagnostic procedure. Refer to the Electronic Manual Temperature Control (EMTC) Module and Electronic Automatic Temperature Control (EATC) Module DTC Chart and follow the ACTION for each DTC given.
If a condition exists, but no DTCs appear during the self-test, GO to Symptom Chart Condition: The EATC System Is Inoperative, Intermittent or Incorrect Operation.
To exit the self-test and retain all DTCs, press any button except DEFROST. The EATC module will exit the self-test and retain all DTCs.
To exit the self-test and clear all DTCs, press the DEFROST button. The EATC module will exit the self-test and all DTCs will be cleared.
Always exit the self-test before powering the system down (system turned OFF). Once the self-test is exited, the ignition switch must remain ON for at least 30 seconds to allow the door actuators to automatically recalibrate.
Continuous DTCs will be deleted after 80 ignition switch ON cycles after the intermittent fault occurs.

 

If it was working when truck went in and truck came back with it not working why isn't dealer flipping the bill? Sounds like they bent one of the cab wiring pins!

 

They are goin to check it out when they have a mech available, and when i have time to bring it in also
