Heat from passengers side

[MrZappo]

First world problems. It happens every 2 hours or so.

Seriously, stop being such a whiner.

That's the solution. Turn it off. Learn to live with it.

That or jb weld the shutter closed.

Call jeep and complain. But your time would be better spent pounding your nuts flat with a ball peen hammer.

It's been years. It will be of no help.

First couple hour trip in 2021 Mojave. Every so often getting moist hot air coming from floor board area. AC is on vents are cold. Temps look good for vehicle.
Help

Is there a small sauna in the passenger footwell? That would do it for sure.

That's the solution. There's no magic wand here.
It can't be programmed off. It's part of the HVAC system. It's been around for years. If there was a way - I find it odd that someone would ask today and get an answer to the affirmative today.
IF you run with windows down, why is turning off the HVAC not a good solution?
It'll have to be, there is no other. It's not broken, it's designed that way for reasons.

You've had other vehicles do this? I haven't.

How would turning if off be a good solution? It's on because you are hot. Windows are down for a smoke or maybe the top is off. AC is on to have a cool breeze.

It does it on a base sport without auto AC, but I am thankful its only a couple seconds and does kick back on. I have not had this on other vehicles but I also have not had other vehicles that I could turn off the highway with the top laid back and drive 5 miles in 4wd through a swamp to get to a wood duck pond

And we aren't engineers, either, and we don't have other specifics to comply with, and we aren't building vehicles that must comply with EU rules or Asian rules.

Much to my wife's dismay, I run the AC with the roof off, panels out, or windows down (because I LEAVE IT ON AUTO AT ALL TIMES).
Since it only happens on longer trips or when temps and humiditys are "just right" it's never happened on local trips shorter than an hour or more. But if it did, I'd figure hey, it's only a few seconds and it's certainly not any hotter than the air I'm letting in through the WINDOWS and since it only happens on the passenger side, even when it does happen, the result isn't big at all. It's limited in time, it's limited in scope, and it's not hotter than the outside air is generally speaking.

I grew up with cars with manual steering, no power brakes, NO AC, manual transmissions and bias ply tires. Having AC with automatic mode is a pure luxury for me. Of my two cars - one doesn't have AC at all and trust me, with headers and all, that thing gets hot inside, especially with clear glass in Iowa. My other car has AC, but it's the sort where you adjust the fan speed and "cool" lever left or right until you get it just right - then you adjust it again 15 minutes later because now it's too cold.
Maybe JT owners are just spoiled, have had it too good for too long with the expensive other cars they have, like Lexus, Porsche, BMW or whatever. For me this is one of the highest end vehicles I've ever owned. It's a HUGE step up for me.
I'm in luxury heaven with this thing! I've never had such a nice vehicle to drive. And I'd not have this thing if not for my father leaving me a few dollars after he was killed in an auto accident and the fact I had to sell one of my collector cars to raise the rest of the money to get it. So thank you, Dad (but I'd much rather have you back.............)

Have I had other vehicles that do it? I don't know how my wife's Grand Cherokee does - for all I know, it does it too! It's HER vehicle so she's the primary driver and usually when I'm with her it's not for long drives. OR, her Jeep sits while we take mine (she loves to keep the miles under 5,000/year as her trade-ins are through the roof and she trades every 2.5-3 years)
So maybe the Grand Cherokee does do it - I never looked into it.
Wranglers do it - I think this goes back to 2018. This is 2021 so that's 3 years. If it was broken, there'd be MOPAR dealer communications and there are none stating this is a problem or issue.

I've had several vehicles with auto HVAC and none of them did this.

I have a 2020 F150 that is my DD and is permanently on auto. It never does this.

I have to second this. How is it that basically every other manufacturer doesn't have this problem, yet we're told it's the way is has to be? Clearly it's not...someone's BS-ing here.

It isn't one of those things where "it works differently, but it still works". Blowing hot air when on A/C is an error. A failure. No way to dice it otherwise. The manufacturer not admitting it doesn't mean it isn't still a real problem.

For all those who always has to have a opinion. I wasn't complaining about the heat. I as well grew up with lead paint, no seat belts , air conditioning wasn't even in the house and as a baby probably had a little bourbon rubbed on my gums. This is a new vehicle only asking is this normal and ok. This is why the world is in the shape that it's in. Don't really care to hear and JT people and what we drive. What does it matter what other vehicles we drive. For those who just responded that it is normal thank you.

 

[MrZappo]

Gentlemen, this is obviously a function that someone put in for some reason and the issue is that you simply hate it ... Its not my favorite thing either ..

But as far as "someone BS'ing" or its a "bug" or a "defect", respectfully no ...

If you drive a long time, it happens on a predictable cadence... Every couple of hours .. at a specific time ... Which means that it is PROGRAMMED TO DO THAT. I have no idea why but it didn't get put in there by mistake ... If I had to venture a guess, there is some percentage of fresh air per mile that some bean counter decided or some government regulation about oxygen levels or some other silly thing. And all of this is dumb as the Jeep is likely the least sealed vehicle available so fresh air is likely not a problem ... But who knows what the real reason that some software developer coded this logic ...

As far as other cars, who cares what they do ??? How is it relevant in any way other than to say that you like the fact that those other cars dont so this thing that you hate ...

It does it, other cars dont, no one can or will tell you why and not enough people have complained to get them to change it ... So, its probably advisable to get used to it and smell the roses (which should be easy due to the burst of fresh air every so often) ...

Oh wow. A bit off topic but do you remember Nylon Tires in winter? Start out, thump, thump, thump until they warmed up a bit???

The point I was making wasn't arguing that Jeep built it like this, but more that the decision to build it like this was an error. The reference to other vehicles not having this is to prove that it's not a required function of climate controls and therefore is completely capable of being eliminated. Intentionally having something function in a way that produces undesired results when it's avoidable isn't okay just because it's "predictable". It makes it negligent. Bean counters or not, this was an erroneous decision made by Jeep and they shouldn't get a free pass on it.

Yes, they should not ... Please call them and let them know this .. As I said, if you can get them to take notice and fix their "error" you would be a legend across several forums ...

In the mean time Ill live with it... Please respond back here with the TSB that they create as a result of your efforts and Ill watch for it ...

I have run this up with the dealership a few times. It would help if people like you would join in to make our voices heard louder!

Clearly I can live with it too. But I will continue to call it out as the flaw it is.

It probably has AC in the seats too. My 2012 F150 did. Greatest feature. Wish Jeep offered AC in the seats. Nothing beats sitting over a stress stream of cold air!
