OldSkoolBMX Posted April 10, 2019 Share Posted April 10, 2019 2016 MKZ 127k miles (yes, I know it's a lot) So I recently noticed when I turn my AC on cold air will only blow out of the passenger middle vent. All other cents blow warm air. I was thinking AC recharge and almost bought some AC Pro but was told our Hybrids dont use regular stuff and it would ruin our cars. Anyways, b4 I take it to the Ford dealer for a diagnostic anyone got any ideas what it could be. Quote Link to comment Share on other sites More sharing options...

I am not an HVAC expert, but here is my Internet diagnosis: The fact that you get cold air out of the center vents would seem to rule out a low refrigerant issue. If it was a refrigerant issue, you would more likely be getting warm air from all registers. Sounds more like a blend door actuator problem, or other issue of that type. Out of curiosity, if you switch the air direction to defroster, floor, etc, what air temperatures do you get? And when you switch back to the dash vents, what happens? Still only cold through the one vent? Hopefully one of our tech members will jump in with more information. Keep us updated and good luck.

From what I can feel it stays warm Quote Link to comment Share on other sites More sharing options...

From what I can feel it stays warm Hi OldSkool. Then in my opinion, it would seem to be a blend door/blend door actuator, or similar problem. If it was a refrigerant issue, you would not be getting any cold air. The air coming out of the "passenger middle vent" is cold, correct? Still hoping one of our tech members will jump in here and hopefully point you in a more specific direction to look. Quote Link to comment Share on other sites More sharing options...

Any idea where to find the location of this blend door and is there possibly 2 since it has dual climate control? Thanks Quote Link to comment Share on other sites More sharing options...

Thanks Hi OldSkool. I keep hoping one of them will jump in too. ? I am sure they will, we will just need to be patient, as they get here when they can. Unfortunately, I can not help you with the location, as my shade-tree mechanic days ended about two decades ago. I'll keep an eye on your thread though, and will post back with any information I can find that may help.

Chris109 Posted April 13, 2019 Share Posted April 13, 2019 Found this. Not exactly for Lincoln but seems they are all in the same area. Looks like these actuators going is common on Ford products. A search will return plenty of hits. https://www.2carpros.com/articles/replace-blend-door-motor Quote Link to comment Share on other sites More sharing options...
