AC blowing warm air fixed

[M&A Sahara]

Had the issue, called the dealer. Heard same story we've read in this forum. Yesterday we go back and talk to service manager.

There is now a software update to stop the warm air blowing every so often with the AC on. Loaded it yesterday, hope it works.

Do you have any more info like a TSB number?

That would help a bunch just in case someone else has the problem. Sadly, many dealers will have no idea there is even a TSB out there to correct the issue. Thanks.

Update: I took the wife's '18 Mustang GT out today, and noticed the AC had the same hesitation before spooling up. I guess it's just one of those things.

My dealer gave me the service bulletin. It took him a while to find it. It’s number 24-006-19.

Thank you!

Oh nice, I wish it was more descriptive but that’s good to know. It’s great that most of the weird little problems from the first year model of the JL are simple software fixes.

Is there anyway you can either scan this into a pdf or take a pic of each page and save as a pdf file and email it to me? PM if you can and I'll give you my email. Actually you may be able to upload it right here so all could benefit.
@JeepCares also confirmed this is the bulletin, not that you needed that confirmation.
Has it resolved the problem in your Jeep?

Took my Jeep in for service yesterday, and explained the warm air problem to the service manager and gave him the TSB that the service director gave me a couple days ago. When I came back after the service was completed, he said they hooked the Jeep up to the computer and it indicated that the software was previously updated. I explained that we were still having the problem, and we had never brought it in for service before. So if the software wasn't the issue, what was? He said it was operating as designed and there was nothing else they could do. I then spoke with the service director, and long story short, we went back to the service bay so the mechanic could show me exactly what they did. The screen indeed showed no update necessary. The mechanic figured out how to force the update, just to make sure there were no glitches.

Today, after about a half hour driving the warm air started blowing again.

I wonder if Jeep Cares?

Prior to this software update, it technically was considered normal operation. It still actually may let outside air in but it may just be a LOT quicker rather than a few mins of warm air while the AC is on...

I had mine fixed yesterday, when I had my oil changed. They argued about it being normal, until I handed them the TSB number, and demanded they look it up. It is blowing much colder than before, for some reason.

This is our fourth Jeep and probably our 50th vehicle overall. None have ever blown warm air in periodically when we have the a/c on. I cannot see how this in any way can be considered normal.

They “consider” it to let “fresh” air into the cabin. I’m sure it’s eventually going to be eliminated soon enough once they get a software update that completely stops it
