SOURCE: EATC Heater Blower Inoperative

I would suspect the blower resistor based on your description. The resistor is located under the hood on this vehicle

SOURCE: EATC (A/C) has no power, no lights, etc

Check fuses # 16 and #23 15 amp (blue) at fuse panel under left side of dash left of steering column. You can check for power to EATC module at module connectors, violet and orange wire and light green and yellow wire. Hope this helps. Have a good one.

SOURCE: blown fuse?

you have a failed door latch . you will have to remove door panel and window regulator to get to the latch. you can check this by closing all doors then open one by one when you open one see if you dome lights come on if they do that latch is ok. common issue. water gets into the electrical portion and kills it. most likely just drivers door it is opened the most. 1-2 hours at a shop and problem should be gone.

SOURCE: My instrument panel on 1987 300ZX stopped workin

Its the connection to the power supply module that is connected to the intrument panel. Its about the size of a cigar box and is silver and is left of the stereo. you will need to remove the panel under the steering colum to access it. wiggle the harness that goes from the inatrument panel to this power supply module until you instrument panel works again. i don't have a permanent soution except to buy a new panel. I am dealing with the same problem.

Which fuse is for the a/c in the ford f150 2005


For the EMTC ( Electronic Manual Temp Control ) and EATC ( electronic Automatic Temp control ) systems the AC fuses are :
F32 feeding the coil on the AC clutch relay
F11 feeding the normally open contacts on the AC clutch relay ( which powers the AC solenoid

The blower motor ( for AC or heat ) is F116 which feeds the blower motor relay

Where is the electronicnautomatic temperature control module located on a 05 ford 150


I assume you have checked all fuses. It could be the heater control switch , the blower motor resister , I would start testing if power is getting pass the switch to the blower motor.

Heater displays everything but you cannot turn anything on ac will not turn on neither will the heat the buttons will not even light up please help


From the equipment description, I take this to be a EATC ( Electronic Automatic Temperature Control ) system.

You can try to run the EATC diagnostic test & recalibrate ( once you have confirmed it is not a fuse )

Electronic Automatic Temperature Control Module On-Demand Self-Test The 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 EATC module on-demand self-test. Make sure to retrieve continuous DTCs by carrying out the Electronic Automatic Temperature Control Module - Retrieve Continuous DTCs procedure before clearing any continuous DTCs.


•The EATC module on-demand self-test will not detect concerns associated with data link messages like engine coolant temperature or vehicle speed signals. A diagnostic tool must be used to retrieve these concerns.
•The 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°-38°C (40°-100°F) when performing 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 Automatic Temperature Control Module Diagnostic Trouble Code Index and follow the ACTION for each DTC given. See: Diagnostic Trouble Code Descriptions
•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. See: Symptom Related Diagnostic Procedures
•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.

Electronic Automatic Temperature Control Module - Retrieve Continuous DTCs
The EATC module will retrieve only continuous (intermittent and hard) DTCs when carrying out this procedure.


•Retrieval of continuous DTCs can be initiated after cycling the ignition switch from OFF to ON. Normal operation of the climate control system stops when retrieving continuous DTCs.
•To retrieve continuous DTCs, press the OFF and DEFROST buttons simultaneously and release, then press the RECIRC button within 2 seconds . All vacuum fluorescent segments will be displayed if there are no continuous DTCs present. Continuous DTCs are indicated by the presence of the degrees Celsius symbol (°C) on the EATC module display. Record all DTCs displayed.
•If any DTCs appear, carry out the diagnostic procedure. Refer to the Electronic Automatic Temperature Control Module Diagnostic Trouble Code Index and follow the ACTION for each DTC given. See: Diagnostic Trouble Code Descriptions
•If a condition exists but no DTCs appear, GO to Symptom Chart Condition: The EATC System Is Inoperative, Intermittent or Incorrect Operation. See: Symptom Related Diagnostic Procedures
•To exit and retain all continuous DTCs, press any button except DEFROST. The EATC module will exit the retrieved continuous DTCs mode and retain all continuous DTCs.
•To exit and clear all continuous DTCs, press the DEFROST button. The EATC module will exit the retrieve continuous DTCs mode and all continuous DTCs will be cleared.
•Always exit the procedure before powering the system down (system turned OFF). Once the procedure 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.

Electronic Automatic Temperature Control (EATC) Module and Electronic Manual Temperature Control (EMTC) Module Cold Boot Process The purpose of the cold boot process is to allow the EATC or EMTC module to re-initialize and calibrate the door actuators. To carry out the cold boot process, follow the steps below.

1.Turn the ignition switch to the OFF position.
2.Disconnect the EATC or EMTC module electrical connectors.
3.Wait one minute .
4.Connect the EATC or EMTC module electrical connectors.
5.Turn the ignition switch to the ON position.
6.Select any position except OFF on the EATC or EMTC module. The EATC or EMTC module will now initialize and calibrate the mode doors. Calibration of the mode doors will take approximately 30 seconds .
