Just took delivery of our 2020 Gladiator last week and absolutely love it!

Has anyone had issues with hot air blowing out at settings of 60 or higher? If we bring it to Low and begin feeling cooler air and then increase to 65 it's fine for a moment. Then, hot air begins to blow and it feels the same if we have it set at 65 or 80.

Dealer looked at it and told us no codes showed up when analyzing and that there have been no issues reported, however this doesn't seem right. They recommended we drive it for a bit and see what happens.

Any thoughts on this would be appreciated. Thanks!

Try doing a search. There are a lot of threads on this topic in both the JL and JT forums.

I have been in the same boat, try to find other posts or fixes but without any luck.

I have the same issue. If I start my temperature at a warmer setting, it will not decrease temperature unless I drop it all the way to low. Even at the setting 65 degrees it will still blow super hot. And that is with even the AC turned in. Once I get to low, it will blow cool.
This is very frustrating with a truck that has 200 miles.

The more I think about this, the more sense it makes that it does this. The heating system is setting the ambient cabin temperature to the temp you select. In situations where the cabin is below 60, it has to heat the air to reach that temp. ā€œLowā€ just likely blows the coldest air the system can achieve regardless of the cabin temperature.

Itā€™s purely an assumption that your gladiator does not have this issue. There is not a logical reason that the air coming out of the vents blows heat (as if on HI setting) when thermostat is set to 65 degrees. Every one of my cars, which includes a 1966 L72 Corvette, at least has a fully working heater

I should have been clearer. I too have noticed hot air coming out of the vents when set to 60 on days where the ambient temp is 30-40. Is it unintuitive? Yes, but it also makes some sense to me.

Hello everyone ..... I now have my Gladiator in again for the second time and they are getting Star involved, however I was just told everything checks out which makes no sense at all. I just left a message for my service case manager at Jeep Wave to discuss this further.

The loaner jeep I received while it was in the shop, which was a Sahara, had none of these issues. Air set anywhere between 60-68ish or so was not hot air. Not until I go above that did I begin to feel warmer air. The temp outside at this time was in the 20s so I was able to compare the Gladiator and the Sahara on the same day.

Also, if you set to 60 degrees and Auto, the air is hot the entire time .... never does it decrease in temp to make it feel comfortable.

I hope they figure this out.

Will keep updating as I find out more.

I asked a Jeep mechanic about the problem we are having. Without looking at the car, he said it sounds like the blend door is not fully opening
