Heat sensor

2021 Gladiator Rubicon.
Every once in a while, while A/C is running, we’ll feel it get warmer suddenly.
Some warm air entering, seems to be coming from below, then back to normal.
Went to Jeep said everything is perfect.
It continues to happen.
Heat valve?
Appreciate opinions.

Do you have automatic climate control?

Yes, we set the temp for each side.

Yes, we set the temp for each side.

Then it's probably sensing that the cabin temperature got lower than the set temperature, and turning on the heat to compensate. Does it still do it if you turn the temperature down a few more degrees?

No.

It does this every 45 minutes or on some cadence like that. It is a cycle to let in fresh air. And it is dumb.

Do a search and read. There are hundreds of posts about this.

We are in Florida 85-95 these days, never seen cabin temp go lower then set

Haven’t tried to lower further

It's by design. As mentioned above, so many threads about this.

AC blowing hot air and can I change tires with no lift account for like 60% of the threads here it feels like.

So just live with it

It's a Jeep thing. And can you change tires without a lift?

No. It's a refresh mode.
If the cabin temp gets to goal, it simply shuts down the AC air. Auto mode controls fan and temperature and is very accurate. There'd never be a need for it to allow warm air in because it got too cold. It would simply stop blowing cold air.
It certainly was NOT colder than the temp we had it set at (67) when mine did that on a long trip.
This has been discussed for way over a year, in detail and at great length. No mystery to it.

For $75 grand I don’t want “a Jeep thing,” Thank you very much.

This happens while driving or at a stop?

Driving, and lasts about 30-45 secs

I never timed it but believe it wasn't any longer than about 20-30 seconds for mine. And it only happened on long trips, and only when the outside conditions were just right. I could drive it for an hour today and it probably wouldn't happen, but if it's hot in 2 weeks when I head to IL for a car show, I expect it may happen once or twice on that trip - on the other hand, I've driven it for an hour or so and never had it kick into "refresh mode". I never noticed it at all the first summer - but this summer has been crazy weather-wise, ultra-humid, much hotter than typical for longer periods. (and our trees are losing leaves, turning yellow and the corn is already brown and beans are dropping leaves although far from mature)
