On three different occasions, AC blows hot air out of the two driver side ducts. Passenger side still has cold air.


Nothing seems to work except letting the car sit for about an hour. After that amount of time, the AC works fine.


It usually happens when the engine is hot and after making a brief stop (less than 5 minutes). When I come back and restart the car, I get hot air.


I have tried restarting the car, changing between heat and AC and changing the temperature setting and no luck.


I have it into the dealership twice with no luck. Problem started at about 20,000 miles.


Anyone else with this problem.

Had the exact same problem first they could not diagnose it. but they did and it was a blower door malfunction. get it back before warrentee expires.

Bingo!

I've had the exact same issue and they told me no reported issues before like this. Now it happened again yesterday. I'm having several issues now so I guess I'll need to take a vacation day to let them have my car all day. Thanks for the info on blower door malfunction, I'll mention to them when I call for next appointment

2015 MKc hot air from A/c

I have had issues since around 20,000 miles. First time hot air coming from driver side air vent next to door. 2nd time was the driver side middle vent. 3rd time was both drivers vents and this 4th time again the drivers side both vents. Blowing hot air. Changing the temperature does not work. Changing the a/c to defrost does not work. Changing a/c to heat does not work. Turning off the car to do a reset does not work. 1st time they changed the actuator. Then a couple of months later it does it again. When I get the time to take it to the shop the dang thing starts to work again. They cannot get a "code" to find out what is wrong. Currently have almost 40,000 miles on it and cannot get an answer as to what the problem is.

had the same issue yesterday. Went by the Ford dealership (my Lincoln dealership went out of business 3 months after I bought the darn thing) and made them feel the vents. Tech said it was something to do with the dual air module but can't fix it until Friday. Luckily when I started it this morning it worked. I'm at 26k miles and no longer in warranty...

Mine did this 1 time last week also. It wasn't blow "hot" air, but it was warm compared to the passenger's side. The next power cycle, it was fine, and never happened since. Luckily, I'm still well under warranty in case it happens again.

I had this happen on a Chrysler, it was NOT a cheap repair. Lots of labor to take the dash apart.

Thanks for the tip. I'll try that if it happens again. I tried turning everything off and on again, but didn't try turning heat on all the way.

The Chrysler problem (and Jeeps) was the damper door motors were so strong that they actually broke the stops molded into the duct and they traveled beyond where they were suppose to stop and yes it was an expensive fix... The MKC may be just a software flash.

So what did the problem turn out to be and did the dealership fix it? Cost?

I have a 2017 MKC and had that same issue the day I drove it new from the dealer! I drove it back and made the mistake of turning the engine off to go in to find a service advisor! Of course the issue wasn’t replicated! Since that day in April 2017, I have it at the dealer 3 times for that and other electrical issues, without resolution. The ac malfunction happens too many times to count!

I just took mine in for this problem and the service department called and said they need to reprogram the front integrated control panel. It will cost me $85.

There is another thread on the forum ( I can't find it now ) where someone suggested the drivers side vent flap gets so hot it expands and binds against the ducting - when it cools off and contracts then it moves freely again - this could be the simple reason for the problem.

Can you tell me what your problem was? Please I need help with my 2015 mk c

 

[Brannigan]

It only happened to us one time - I had the drivers side blowing hot air around 26 C and the passenger was blowing cool around 16 C - after a while I couldn't get the drivers vents to drop temperature - stuck blowing hot air. I shut off the climate system. We had to stop for a while and when we got back under way again the problem was resolved. I really do think it's simply that the vent flap gets too hot, expands and binds in the duct just enough to jam until it cools off again. It's never happened again because we simply make a point not to turn the heat up that high - 23 C is plenty warm for us even in the winter here in the Maritimes.

I am pretty sure it is bad coding in the fcim. I flashed mine to the lastest coding and have not had that problem anymore.
