AC / Vents

[MDRAPTR]

So 800 Miles in & today i had fan all way up level 7 & got level 1 flow but heard the fan blowing hard to which seemed like no where. Get home leave 2 hrs later back to normal blowing fine. Anyone have this issue?

Same thing happened to me today in my Gen 3 with 16k miles. AC stopped working but you could hear it working hard in the dash. Took it straight to ford and they said it was common on the new f150’s. Frozen! Have an appointment next week. There’s a bulletin out about it. Now my dash gets to get ripped out. Pretty cool.

As a first time Ford owner, these are the types of things I’ve always worried about. And this AC thing has been around for a long time according to a ford buddy

Issue: Some 2015-2022 F-150, 2017-2022 Super Duty and 2018-2022 Expedition/Navigator vehicles may exhibit poor air conditioning (A/C) performance, loss of airflow and/or engine cooling fans running continuously from high A/C pressures. This concern may be from the evaporator freezing up due to the evaporator temperature sensor being biased. To correct the condition, follow the Service Procedure steps to replace the evaporator temperature sensor.
Action: Follow the Service Procedure steps to correct the condition on vehicles that meet all of the following criteria: • One of the following vehicles:
- 2015-2022 F-150
- 2017-2022 F-Super Duty
- 2018-2022 Expedition/Navigator
• Poor A/C performance
• Engine cooling fans running continuously

Repair/Claim Coding
Service Procedure
1. Run the A/C on maximum/recirculation and blower speed on high for at least 10 minutes with the engine idling,
then drive the vehicle.
2. Using the datalogger on the appropriate Ford diagnostic scan tool, pull up the EVAP_TEMP PID in the front controls interface module (FCIM) to read the evaporator temperature and use a thermometer to measure the vent outlet temperature. Compare the temperature reading of the EVAP_TEMP PID to the thermometer's vent outlet temperature reading during A/C use.
3. Is the temperature reading shown on the vent outlet thermometer colder than the temperature reading of the EVAP_TEMP PID?
(1). Yes - proceed to Step 4.
Causal Part:
19860
Condition Code:

(2). No - if Step 4 directed to restart this article, the repair is complete. For all others, this article does not apply. Refer to the WSM for normal diagnostics.
4. Recover the refrigerant and review recovered refrigerant amount. Was the correct amount recovered within +/- 1 oz. (0.03 kg.)?
(1). Yes - replace the evaporator assembly. Refer to WSM, Section 412-00. The evaporator temperature sensor is part of the evaporator assembly.
(2). No - refer to the WSM for normal diagnostics. Once the root cause of the incorrect charge has been corrected, restart this article from Step 1 to confirm the customer concern is corrected.

Mine was doing the same thing when I would toggle the fan speed, but then once I hit the "MAX" button the air seemed to come out twice as must as it did on level 7! When I toggle back to level 7, the truck blows much better than it did before.....until I turn the truck off and start the cycle over again. It seems like its a damper that is not opening properly behind the dash.

Wonder if that’s why my left vent sucks ass. The rest of the system works great

Unfortunately this is your fix. But it corrects the problem.
