AC Shut off Issue

[Wakesnowb]

Same thing happened to me twice so far. First time was right when I started truck up, the auto AC gets going full blast then shut off completely. I then messed with the manual buttons and all worked fine. The other day right after I started my truck and went from reverse to drive, it wouldn’t idle forward, got stuck until I gave it some gas to go then was fine. Then today I start the truck and the auto AC comes on full and then 1 minute into driving away after making a u-turn in parking lot, the AC shuts off and truck hogs down like low idle. Gave it some gas and AC started again on its own and all seemed fine. Truck was flawless until this. What gives? I am hoping it’ll just go away. My truck is a 2019 and doesn’t seem like any software updates ever get sent to it ever...same as most people with the 8.4 screen not that a software issue would fix this or not..

Same thing has happened to me here in Florida...two of the 10 or so times this has happened the truck shut off and I had to throw it in park and restart. AC has come back online in about one minute. Feels like a power shift is happening or the alternator is not able to keep up with the load from the AC

Funny to see this I bought my ram this past August. I was driving down the road with a/c on low made a left hand turn and it completely shut off came back on a minute later. This is the first time it happened this past week since owning the truck.Getting a little frustrated now. First my fog light on drivers side was the passenger fog light upside down to fit . Had my steering rack replaced due to the steering sticking on left hand turns also have a horrible brake squeal that the dealer hasn’t fixed which is making me mad you can only clean up the brakes so many times and no difference. It gets very frustrating that the dealers are afraid to fix anything without rams approval. Time to step up on customer service Ram. I don’t mind having problems with this vehicle but to jump thru hoops to get things fixed is ridiculous. Love my Ram hate the way Ram makes the dealers have to prove something is wrong before they fix things and the fact to get anything fixed you have to call ram to escalate the situation. The fact @RamCares actually needs to start caring. Take care of your customers and your customers will take care of you. That simple.

Thanks for the info, I really appreciate it! I'm hoping I won't have to go down this road, but my truck is a major safety hazard (see post titled "truck died last night" for the full story). From what I've read, North Dakota lemon law is pretty straight forward, but it can be a real pain in the ***. I'm sitting at 6000 right now for miles.

Mine has the same issue with shutting off and then kicks back on after a minute. It happens randomly that the dealership cannot duplicate. Just the other day I took a left hand turn and the engine shuddered and ac shut off and kicked back on in a minute. Getting frustrated that this happens to a 50k + new vehicle and there is no fix for it. Ram needs to get this resolved and find a solution. I like my ram but just frustrating dealing with it.

Well my 2020 does the same with no rhyme or reason.

 

[JDBob35a]

Add me to the list with this weird problem. I've had my AC quit three or four times, minute or so later it comes back on. When it shuts off it's like a switch, just drops out.
Pretty sure all my instances have been after a right hand turn and starting accelerate.
Of course the dealer's never heard of it, and can't duplicate it.

Okay, so I have a 2019 Laramie 5.7 Hemi w/o the electric torque motor. I live in Florida and several times in the past few months the A/C has shut off shortly after starting and driving. It usually slowly comes back on after about 15-20 seconds. This usually only occurs on days when its above 90 degrees and it's been sitting in a hot parking lot. I too believe that the A/C does not routinely blow cold enough on hot days. I mentioned it at my last service appointment (about a month ago) and the Service Adviser indicated he had not heard of any similar problems. And of course they didn't duplicate it. However, another service adviser reported that it's normal for the AC to shut off and purge hot air from the vents.
Well today, it was 93..(high humidity) hot parking lot, and the blower shut off and came back on only to go off again and again repeating about 4 times in 10 minutes. However, this time it wouldn't come back on until I shut the truck off and restarted the engine. Each time the A/C was set to Auto/ Recirculate. After restarting and the A/C came back on it continued to shut off and eventually would only blow a fan speed of 3 with the Recirculate button off. No other adjustments could be made without the A/C shutting down entirely.. This went on for the entire 56 mile interstate ride home with barely any cool A/C.. Got home, restarted the truck and it appears to be operating normally but the temps outside had cooled to 87 due to rain in the area. I plan to have a dealership look at it again. Today was different and more severe! There is nothing "normal about this malfunctioning A/C on a $50K truck! I'll be going to a different dealership service center this time as I have no confidence in the dealership that sold the truck to me and apparently only had one A/C tech for a huge dealership!

I am deeply sorry for the trouble, @2019Laredo. I would be more than willing to escalate a case on your behalf for further support as you work with a new dealer. Our team is always a private message away.

I have an apt with the ram dealer on sep 3, 2020 for this issue again. The first time it was there for those recall and they ran a diagnostic and system program check and everything came back good so no solution at that time. Well see what happens on sep 3, 2020

Same issue here. 2019 RAM Lone Star. 11K miles. Obtained a copy of the STAR case from the tech at the dealer.

Recommended actions straight from FCA engineering:
1) Verify HVAC blower motor is operational. (Done)
2) Clear DTC B10EB-4B (Done)
3) If (blower) motor is operational a service software flash is planned for 4th quarter 2018 a replacement (blower) motor will not change current operation (pending)
4) If blower motor is not operational replace the blower motor (NA)

So the big question remains where is this software flash. My truck sat for a week at the dealer trying to obtain the software flash, which still has not been obtained. I picked up the truck and will wait for them to obtain the software flash.

So a follow up on my issue as explained in a few posts above.
I took my 2019 Laramie to a dealership regarding the A/C blower shutting off in high temps. They advised the system produced some fault codes: B10EB-48>Blower, power module over-temp and B10EB-19 Blower power module over-current. The software was up to date and they've ordered a new blower motor. Probably be a couple weeks before they get it. So at least they found something and I have the vehicle till the part comes in.

I have a 2020 Lonestar Night Edition with this issue. The ac will shut off randomly and over the last month its been increasing. Sometimes the ac will come back on its own after about a minute while other times it never comes back until restarted. The issue only happens when its hot. The Blower motor has already been replaced and I believe the power module as well due to codes similar to 2019Laredo. The truck has been in the shop a total of 3 times and I'm starting to lose hope. The dealership is working with Chrysler to resolve but pretty bad when the truck is new. I don't know if I should keep it, trade it, or beg Chrysler to help replace it if they can't fix it. It doesn't seem like anyone has a solid fix. This will be my last FCA vehicle if I'm left stranded as this will affect me financially being a student.

 

[Mixedbrees81]

Dropped off my truck to the dealership on 02 sep 2020 and got a call from them yesterday saying it has a blower motor over temp. Reading all the other post this will more than likely not fix the issue as others have been thru this process. I know this is the steps they have to go thru but seems like dealerships need to communicate with FCA so they can send out notices to other dealership stating this is not the fix. Theu need to find a solution to this or buy the truck back. Have very low expectations of the blower motor fixing the issue, blower motor comes in on tuesday 08 sep 2020

 

[Mixedbrees81]

Correct me if I'm wrong but seems like everyone on here that has this issue has at least a level 1 equipment package. Anyone here with a base model have this issue?

I have had this issue since my truck was new. 2019 Limited Hemi. two different scenarios. coming to a stop and pulling something. I can recreated it everytime anytime i want. for those who are having the issue and can do this . Tie your truck to a tree and pull or you can push against it. With just a very limited effort on the truck the A/C will cutoff. everytime. i had mine cutout 6 times in less than 15 minutes of repeating these steps. i have had a truck for over 30yrs and have never had a truck do this and i have had all brands chevy ford and traded in a 2500 ram that did not do this. It is scary to me that the electrical system cannot handle this type of loading on it. Maybe Ram engineers need to test a truck to be a truck instead of being a car. guess they don't have many trucks in India.

I took the truck to a different dealer and they replaced the blower motor again. I'm not sure what I'm going to do with this truck. The dealerships are trying to help me but FCA closed the ticket on them. The only response they get is the issue is known and there will be a fix one day. Rediculous
