AC Question

[Nitro]

Hey all...New to this forum but thought i would sign up so i dont feel left out in the cold. lol.. I just bought a 2013 FFH..everything has been working like a champ...but this am when i got into to it to come to work.. i noticed my ac was set on 60 and when i tried to raise it up in recyc. ac mode..it blew hot air..it hasnt done this before.. I have read alot about ac stuff but has anyone had this same issue? Or is it just something i need to deal with? Thanks!

If you turn the temp above the interior car temp the car will cycle hot coolant through the heater core to blow hot air.

 

I'm moving this topic to the appropriate section.

Probably only time will tell.

 

The auto climate control does seem to have a few "quirks".

With my '14, a couple of times when trying to switch it off of "max AC", it has left the temp set to LO and the fan at max.

One time I just changed the temp.

The next time, I turned it OFF for a minute.

For the past month or so it has stopped doing that and switching from MAX to AUTO seems to work right.......?????

A few weeks ago, I had a glitch in my climate control (CC) that sounds quite similar to what the OP may have experienced.

 

I always have my "My Temp" setting set to 82°, so that when I get done with my trip and am ready to turn off my car, all I have to do is hit the "My Temp" button, so that the A/C doesn't blast me out of the car quite so bad when I go to turn my car back on when the outside temps are between 100° and 115°. Then as the temp inside the car decreases and the A/C air temp starts to increase, I start turning the temp setting down 1° or 2° degrees at a time to get the A/C air temp to blow cool air once again.

 

So that morning when I turned on my car on to go to work, the outside temp was about 90°, and it appeared to me like the MFT screen quickly flashed irregularly, and then I noticed the temp setting on my CC was not at 82° or even something like 74°, which it would have been had I forgotten once again to hit the "My Temp" button before I turned my car off last. But this morning the CC temp setting had glitched to a setting of 66°. So I quickly hit the "My Temp" button to try to get it back to my normal 82° initial setting, but the temp setting had seemed to reset itself back to the default "My Temp" setting of 72°. AND, it was blowing hot air. The outside temp sensor was reading about 90°, so it was not the temp sensor that had gone wacky, even though I have had minor cases of the temp sensor being stuck on something like 86° when I got into the car when I knew good and well the afternoon temp had to be closer to 100°. But then the temp sensor in those few minor instances would recover in a minute or two, and jump about 5°, 10°, or 15° at a time, until it reached the correct outside temp.

 

I was in a big hurry to get to work that morning, so I didn't want to pull completely off of the freeway and waste all the time that would be required just to investigate the glitch in my CC. So I started trying adjusting the CC settings while I was driving down the highway to try to get it to blow cold air instead of hot air. But when I turned the temp settings down to colder settings (lower numbers), the air only blew harder and hotter. I even tried rolling the windows down some to get some air to help cool me off, but since the outside temp was hovering above 90°, that only made me hotter and sweatier. I tried every combo of settings I could think of, and I finally found that the _only_ way I could get cold air to blow out of my CC vents was to set the temp setting to "LO", which I had discovered by hitting the "MAX A/C" button a few times between trying other CC settings. After I had set the temp setting to "LO", I could then turn the fan down to even the lowest setting and I could also use any of the vent outlet settings and it would still blow cold air. But even on the lowest fan setting, it would get quite cool in my car with the temp having to be set all the way down at "LO". So I ended up cycling the CC completely on and off myself for the rest of my commute so I could regulate the temp inside to be mostly comfortable.

 

So then after I got to work, I tried turning the car off and back on, since I figured there was a good chance it was just another one of the many glitches that we FFH owners experience from time to time since there are so many computer modules installed in our cars. But my CC was still blowing hot air after turning the car off, no matter what I set the temp to except when it was on the "LO" setting.

 

So after I dropped off my stuff at my desk, I went back out to my car to take it to the dealer for them to look at it. But before I started up my car, I had one more idea to try to try to fix my CC, since I was sure it was a glitch condition. So I started up the car, turned the CC completely off, and I then turned my car completely off, and even locked the door from my fob while still sitting in the car. I waited for at least 30-60 seconds, working up another sweat while sitting there in a the 90°+ car.

 

And then when I started up the car, and turned the CC back on, it was once again blowing cold air on any of the A/C temp settings. So a trip to the dealer that day was no longer needed. :drop: :dance:
