Ford Fusion AC Not Working

Ford Fusion owners: Beware if your A/C has stopped working!

Ford had a genius idea to install a sensor on the top of the evaporator case. What does this mean to the owners of the Fusion? I should start by saying there are many reasons why your car's A/C can stop working. But on the Fusion, if the A/C compressor is not turning on, you will need to change the Evaporator Discharge Air Temperature Sensor.

The sensor tells the computer what the air's temperature is at the exit point of the evaporator. When it senses that it's cold, it turns off the compressor. Otherwise, the system would freeze.

Well, sometimes these sensors short out and will not allow compressor operation. Ford is well aware that the sensors are faulty. So I suggest that if your Fusion has low miles and is out of warranty, you contact Ford and demand they repair it.

I have changed the sensor on cars as low as 22,000 miles (but it was over three years old). The problem is that you must remove the entire dashboard to change this part and there is no way around it.

The total labor for this job is 6.7 hrs, and the part costs $17.49. Depending on your area, the average price for the job would be around $600 + tax. I do it for $500 out the door. I have heard of people paying in excess of $800! If you are the do-it-yourself kind of person, I will attach the instructions on changing the sensor yourself below.

  • Remove the instrument panel.
  • Detach the A/C evaporator discharge air temperature sensor.
  • Disconnect the sensor's electrical connector.
  • Remove the sensor.
  • To install, reverse the removal procedure.

How to Remove the Instrument Panel

CAUTION: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.

1. De-power the supplemental restraint system (SRS).

2. Remove the floor console.

3. Remove the LH and RH instrument panel end trim panels.

4. Remove the weather stripping from the front door openings near the instrument panel.

5. Remove the A-pillar trim panels.

6. Remove the RH and LH cowl kick panels.

7. From behind the LH kick panel, disconnect the two electrical connectors.


8. From behind the RH kick panel, disconnect the bulkhead electrical connector and the antenna lead-in cable.

CAUTION: To avoid damage to the bulkhead electrical connector, be sure the release handle is in the full UPWARD position before disconnecting the electrical connector.


9. From underneath the glove box, disconnect the three A/C electrical connectors.


10. Disconnect the electrical connector and retainer located on the floor between the two front seats.


11. NOTE: To make sure of proper location during installation, index-mark the position of the steering column shaft before removing the pinch bolt. Remove the steering column pinch bolt.


12. Remove the instrument cluster finish panel.

13. Remove the instrument cluster.

  • Remove the 2 screws.
  • Remove the instrument cluster.
  • Disconnect the electrical connector.

14. Remove the two instrument panel center brace bolts.

  • To install, tighten to 20 Nm (15 lb-ft).

15. From through the instrument cluster opening, remove the two instrument cluster opening bolts.

  • To install, tighten to 20 Nm (15 lb-ft).

16. Remove the two instrument panel lower bolts.

  • To install, tighten to 8 Nm (71 lb-in).

17. Remove the instrument panel. CAUTION: To avoid damage to the instrument panel, this next step requires the help of an assistant.

  • Remove the three instrument panel cowl side upper bolts.
  • To install, tighten to 23 Nm (17 lb-ft).

CAUTION: To avoid an improper connection at the bulkhead electrical connector, be sure to position the connector for installation then push the release handle to the full DOWNWARD position until it clicks. To install, reverse the removal procedure.

  • Re-power the SRS.
