heating system and air conditioning system temperature problems

Lately the temp control will not change the temperature either up or down with or without air conditioning unless I turn the key off or turn of the climate system at the display panel and then turn it back on then it will go from the last setting position to the new temperature. Anybody else run into this. All other functions work in the climate system it seems.

doug515,

Is this something that you are able to replicate on a regular basis? I haven't found any information detailing these specific symptoms. Have you had an opportunity to speak with your servicing dealer?

Being a 2013, you are likely still covered under warranty if a defect is found.

Yes it does it on a regular basis, at first I thought it was an intermittent problem but after figuring out it was only changing temp to the new one after the key was switched off, or the climate control was switched off at the panel, did I figure out what it was actually doing, then it was simple to replicate the problem. Has been back to the dealer a second time yesterday, first day it had the HVAC module replaced, now the recirculation door actuator has been replaced, it seems to have fixed it but will test it again today when I am out and will post the results here.

Mine is doing the same thing. First trip they checked for updates and re-calibrated the vents with no luck. Second trip they decided the HVAC module is bad and ordered a replacement. Just waiting for it to arrive, however, they've since told me they've had to order 3 additional as I'm not the only one having this issue. All 2013 300's, too.

Seems to be good now, so in the end they replaced the HVAC control module and the actuator. It still had the problem after just the HVAC control was replaced so dont know if it was an actuator problem only as that was replaced the second trip after the HVAC module was put in. It would seem it needs the actuator replaced for sure and maybe the HVAC control as well.

Awesome!! Looks like I'm not alone.. 13 Motown here...

If say I shut the car off and it's at 72.. When I get back in it will blow hot air all the way down to 63. Sometimes even down to low.. When that happens I found turning it all the way up to hi for a few then down it will adjust normally...

I have the same issue on my 2013 300C. Went to the dealer today, and they will look at it when I get back from my next business trip in December. The service adviser looked through a database and couldn't find a recall or any other information about the issue.

The specific situation today was outside temperature in the 60's, climate control set to 70F, system was blowing HOT air when when set to LO on the control panel. I manually switched on the A/C and set the car to manual climate control mode. Problem persisted, to where I was sweating in the car and drove with the window open and the ventilated seat set yo HI. Once I restarted the car it seemed to work as expected, keeping the temperature around 70F. This has happened a few times now since the weather has turned from hot to cold here in TX ...

I had very similar symptoms and (are you sitting down) it was fixed by replacing the sun sensor. Apparently the sun sensor is an integrated unit with a "multiswitch". My multiswitch went bad. It took a good half hour before my car would heat normally, rather than roasting me alive. I could live in my car with the temp setting set to low, and I could slowly raise that up over 1/2 hr before the car blew anything like the commanded temperatures.

Just to update everyone one how this issue was resolved for me:

The mechanic at the dealership checked the logs on the car and found this:

2 active DTC's:
B1058-13 for recirc door control - circuit open.
B105C-00 For recirc travel range too small

He performed an actuator calibration. Test failed. He verified battery voltage on both wires, and determined there was an "internal open" on the actuator.

Replaced recirculation door actuator, performed actuator calibration and verified that all actuators passed at that time. All systems are working as designed at this time.


I have only driven a few hundred miles since this was fixed, but my issue seems be be resolved, so for me this issue is closed for now.

Hopefully this information will someone else when thy have the same issue ...

I'm not having a similar issue. When i turn my car on for the first time of the day it blows hot air even though its maybe 40 degrees outside and i have the temp as low as 62 degrees on the AC. If i go to LO setting it blows ice cold air, go up one notch to 60 degrees and it feels like 70 degrees. Say i drive to a store after turning car on for the first time, park car and turn off, get back in car and turn on, sometimes then the AC will work just fine but not always. Seems odd after i restart the car from scratch AC sometimes works like normal.

I have a 2012 300C and out of warranty now with about 40k miles so hoping it's not a huge charge at the dealer? Any ideas?

Another issue is when i turn the car on from my remote the steering wheel does not heat up on it's own and the driver seat Heat does not turn on automatically like it use to when i start the car with remote fob. I understand it's controlled by the outside climate but lately it's been below 40 degrees and still with auto start the heated wheel and seat do not turn on.

Anyone know the actual car settings for this to work? I though it was anything colder than 50 degrees the heated seat and wheel turns on, anything above 90 degrees and the vented seat turns on automatically via remote fob start? If this is true then obviously this is broke now on my car as well?

I have a 2012 300, and the sun sensor/multiswitch assembly failed and caused these same problems. I had to argue with my service adviser because he insisted "they all do that" because there is a turn-on transient. Apparently he thought I was an imbecile and don't know a turn-on transient when I feel it for a half hour. :mad: Some "transient", eh?

Bring car in tomorrow about the heat again. This is new when I use remote start and let car warm up for 4 mins and steering wheel and seats are not warm, it takes about 5-10 mins for steering wheel and seats to heat up, this can't be normal? How long does it take any buddy elses steering wheel to heat up?
 
#25 ·
So here is what happened last night guess these cars don't like the cold. -23 here and started car let warm up for 3 min. and radio is dead, its just a black screen nothing works at all. I put it in reverse and the backup camera brought the screen back to life,radio turned on and heat came on. Have some ghosts that live in this car.

Same here which is why i haven't taken it to the dealer yet. It's weird first start of the day AC blows hot unless on LO setting then it's freezing cold, 60 degrees and feels like 75. I drive the car again later in the day and AC works normal. Also when AC is having the issue i notice the Automatic feature does nothing. When i turn on Automatic it says automatic but nothing comes out the vents no air at all as if the air is off completely. When AC is working though and i press Automatic it works as it should.

Seems my issue interferes with Automatic AC controls as well if that helps pin point anything?

Do you know the part # and which door actuator it was? Isn't there 4 door actuator on the car?

Well, I got it back today. They checked the wiring and didn’t find anything wrong. The service manager I have been talking to wasn’t in today, but the guy that called said they did a full recalibration of the new actuator for the blending door and it works perfect now. So happy to get this fixed. For you guys that are having this problem, it's just as fieldzy0 described. Replace the door actuator and recalibrate, you'll be good to go.

Thanks fieldzy0! Your postings got my dealer on the right track faster.

Mine is a 2013 - and I have the same intermittent problem. Hot air forever, regardless of temperature or "Auto" settings. While driving on a warm, sunny day, with the car air stifling me, I made sure the A/C was "On", and temp selected about 63, the vents still blew HOT HOT air on me. Finally, while still driving, I selected "Max A/C", and the A/C started to work, and the temps stabilized. I de-selected "Max A/C", and it continued to work properly. I'm building up my confidence so that I can confront the dealer, because I know it will test OK when I go in.

Got car back today everything seems to be working perfect now. The radio issue when remote start wont come on till I put it in reverse was caused to a bad door switch don't know where that is,its the switch that tells the inside lights to come on when door is opened. Heat issue was solved by the usuall replace recirc. door actuator. Seem these cars have faulty recirc. door actuators.

Mines been doing this as well. It'll be crazy hot air until i get the temp controls down to about 63 ish or lower. Then it feels like it isnt as hot. Its been crazy cold here lately so I've been enjoying the hot air either way. But when its too hot, i either have to take the air temp all the way down for it to get normal/cold air, or even it out from dash to dash/foot air so its not hot in my face..

I've also noticed the lowest fan setting seems to be rather high as well... blowing more than it should be. I didnt have any of these issues when i first got the car but they're here now.

So i guess what im getting at now is, how much does a fix like this usually run? (no warranties..)

I would try to see if the dealership/Chrysler is willing to do this for free given that several people here have reported the same issue. This seems to be a manufacturing defect to me, one that's not uncommon and certainly not due to any negligence or wrongdoing on the owners side.

Can't hurt to ask in my opinion, and Chrysler should step up here.
