Unusual Climate Control Issue

[lostlemons]

Really needing some advice, friends! I’ll start with what might be important. Then, I’ll get into the meat of it. Btw, thank you in advance for reading

Vehicle information: 2019 3.6L JL Rubicon unlimited. 4-door hardtop.

Milage: Low—30k (+/-)

Issue: Climate control unavailable—vents blast hot heat while driving, especially at higher speeds

Climate controls types: Digital and analog (operates from U-Connect and/or manual controls below it)

Here’s the deal: : First of all, this occurred about a year and a half ago after a snow storm, which left around 1.5 feet on the ground. I can no longer go without HVAC due to upcoming frequent and long distant trips to different doctors (Recent cancer diagnosis a broken back). My jeep sat unused in temperatures approaching zero for around five days. When getting in to head out and explore our winter wonderland the engine would not crank. So, I got the jump starter out (was new and fully charged). This was the original factory battery. It was around 4.5 years old at the time and had failed me several times prior to the incident I’m about to go further in depth with.

The little, but powerful, jump starter did not due the trick. So, I eventually used my truck (no electrical issues). The battery was so drained I had no choice but to leave the cables connected while elevating the RPMs to 3,000. Finally, after a handful of tries, it cranked over. The cables were immediately removed one it started.

Since this incident I’ve replaced both batteries. Their are no issues with them or their connections.

Here’s where it gets weird. The RPMS were extremely high, as if someone was lead-footing the accelerator. Not only that, but there was an of, sort of sour smell emitting into the cab. It ran this way for around five seconds before I turned it off.

After this I analyzed all connections under the hood. Spent around an hour doing this. Everything was properly connected and all fuses and such were properly seated.

At this point it was jumped again and ran like normal. Furthermore, it has been running like a champ ever since. The problem was, once the wife and I started driving around (it was in the 20s at the time) we noticed the climate control was un responsive. The manual and digital controls would not do anything for us.

This is important: the U-Connect indicates “Climate Control Off”. There is no way I am aware of to turn it back on. Believe me, I spent 30-plus hours researching fixes. I’ve attempted all sorts of reboots, but was only able to reset what I had already preprogrammed (“restored to factory settings”.

I believe a hard reset may resolve the issue… maybe, but I have yet to find the correct method for my particular year/make/model (Unlimited Rubicon with 3.6–digital and analog climate controls). Then again, there was that issue with the temporary high RPMs and that sour scent emitting from the vents.

Now, if we assume this is not a hardware issue, what else could it be? Did I fry a HVAC related part under the hood, or in dash?

I did take it to the dealership. A mechanic unofficially had a quick look and said the U-Connect needed replaced. There were NOT any codes for him to read, so… I don’t think this is necessarily the appropriate fix. Plus, these things are extremely expensive. The mechanic indicated, “they only cost $3,000-$4,000 and I can’t imagine it costing more than 5k$ with labor”

Please, if you have ANY advice, it will be greatly appreciated. My money needs to go toward treatments, not ridiculously high parts replacements. I can try to replace any part(s) myself, as I’m familiar with basic mechanics and electrical. Hopefully it won’t take much reaching, due to the fact of my L2 being fractured in addition to everything else.

Hold the center of the radio knobs in for a few seconds, and the radio will reset. That will usually fix auto climate controls that have gone stupid due to battery problems.
These things go dumb all the time. Might have to reset it more than once.
3-4k to replace the uconnect, now you know why they call them 'stealerships'
There's also a hidden reset button in the (I think) upper right corner of the screen. Thats a hard reset, and I'd only do that as a last resort.

Have someone who isn’t an idiot actually look at it. There is absolutely ZERO chance that there were no faults. There is a separate hvac control module from the unconnect. It’s probably shit the bed.
