GEN 2 - A/C Issue

[Nap925]

I've been trying to trouble shoot an A/C issue. With the warm weather lately, I've been noticing a somewhat intermittent issue. The A/C is cold and coming through the vents but, doesn't seem to blow/flow freely, no matter how high I turn the fan up or if I recirculate or not recirculate, the airflow is low. When the air flow is set on high, level 4 and higher, it sounds like there's a restriction and I don't feel the air blowing as high as it should.

When not running A/C, normal vent mode, air flows fine even at low settings! Sometimes, when I turn the A/C off, and it switches to the "normal vent" mode, air flows freely again. I've found the earlier GEN1's had issues with the vent door/flap breaking but, never found anything for the GEN 2's? Wondering if it's the issue?

Has anyone had similar issues and what was done? Only searches that comes up are for bad A/C smells.

Thanks in advance!

Did you check your cabin air filter?

Yes... I replaced it last month.

Evaporator may be freezing over. The cause can be a biased Evaporator temperature sensor. If you have ForScan, you can compare the AAT and EVAP_TEMP parameters to see if the evap sensor is reading significantly higher than AAT (30 degrees F or greater difference).

Or it’s just standard operating raptor fan, which is the weakest I’ve ever encountered. It’s one of only a few disappointments with my raptor, horrible blowing power. AC or heat

Just a observation but i notice that the AC lowers when you talk on the phone or engage siri. Perhaps thats stuck on? Can you hear the blower fan operating at high speed?

I've noticed that also which is a cool feature.

No fan complaints so far on my 2019.

Check and make sure air isn't blowing out the defroster or floor vents.

Air may be moving but not out of where you expect. That would be an issue with the mode door/actuator

Not on my Gen 2, but on my '18 Expedition same thing. Cold air, but fan reduces to nothing. Dealer said low on refrigerant, but holds a vacuum..... said something about compressor blow off valve that may of happened if it froze up..... or cabin air filter..... we dont know yet.
