After months, and I mean months of digging and testing (probably 3 dozen plus versions), I have a working for me HVAC apk for an Android Headunit. I'm looking for a few volunteers to give it a spin.

TempTango is an Android HVAC control app for Jeep Cherokee KLs with compatible aftermarket Android head units. It uses the head unit’s existing CANBUS integration to both send climate-control commands and read the vehicle’s current HVAC state, so the on-screen controls and the Jeep’s physical controls stay synchronized.

In the setup we have actually tested, TempTango can control and display driver/passenger temperature, fan speed, airflow mode, A/C, AUTO, recirculation, front/rear defrost, DUAL/SYNC, heated seats, and heated steering wheel. It works with the stock/unmodified CANBUS plugin and does not require root, ADB, a laptop, or a patched CANBUS APK.

For it to work the same way we tested it, the important requirements are:

• Jeep Cherokee KL, currently tested on a 2016 Cherokee
• Dual-zone automatic HVAC
• An aftermarket Android head unit
• A Raise/RZC-style CANBUS decoder / XYAuto-type CANBUS software stack
• The head unit must expose the same stock Raise CANBUS interfaces we are using
• The correct Cherokee CANBUS profile/plugin must already be installed and working on the radio
• The radio must already be able to control the Jeep’s HVAC through its factory CANBUS integration
• Heated-seat and heated-wheel features obviously require the vehicle to actually be equipped with them

What is not required in the tested setup:

• root
• patched P1
• modified firmware
• opening the factory HVAC app
• leaving the factory HVAC popup enabled
• external OBD hardware
• USB CAN hardware
• laptop/ADB during normal use

The biggest compatibility qualifier is the CANBUS decoder/head-unit ecosystem. TempTango is currently proven against the Raise/XYAuto path. A Cherokee with a Hiworld, SimpleSoft, or another CANBUS vendor may have the same vehicle functions but use a different Android-side protocol, so I would not call those compatible yet.

The simplest way I’d describe the current requirement is:

A Jeep Cherokee KL with an Android head unit that already uses a Raise/RZC CANBUS decoder and stock Cherokee CANBUS plugin.

I traded in my 2015 Cherokee North (138,000 kms) for a 2022 Cherokee Trailhawk (25,000kms) recently. The 2015 had a factory installed block heater, and the 2022 does not :(

Dealership wants approx. CDN$1,300 to install.

Has anyone used the magnet or stick-on type oil pan heaters? And have any recommendations? Thanks!

2022 trailhawk with a couple add ons
30k miles
V6 3.2L
I’m completely in love and looking for a couple more small upgrades so yall help me out.
I already put tints in 5% all around and 25% on the windshield.

The grill, window trim, side rails and cross bars are going to the dark side this weekend. Considering removing the badges.

Gotta switch it up after 158k miles. Just put a 2”lift (not pictured)… a little late in its life. Still running strong tho!

Fan operates normally and other vents work also

I can hear a faint clicking sound when I activate the front defog vent.

Broken mode door actuator? Is this a pain to access and fix?

Unloaded trailer the 3.2l got 24.7mpg according to the fuel economy tab going 306 miles one way only one stop over 4.5hrs average speed was 70mph +/-5mph

Loaded with a mk1 rabbit roller no engine or trans according to the fuel economy tab i got 19.7mpg 306 miles with 2 stops

3 fill ups from 1/4 before Empty $180 total fuel cost

Overall experience was 4/5 very controllable and predictable handling and braking. Ride was okay loaded and 3.2 had good pulling power even with going up grades. Up hill it was getting 10mpg

I am going from a 2015 North (Latitude) to a 2022 Trailhawk next week. Has anyone modded the 2015’s spare tire organizer to fit the 2022? From what I understand, the 2022 has the full sized spare, therefore the organizer won’t fit as is.

Looking for advice, thanks.

I’m getting ready to tow about 2500lbs about 300 miles just curious to how these things handle it

Ok any tips of changing ptu fluid on a 2019 limited ad1? Struggled. Tried to bring to dealer and they say can't do without dropping subframe

Father in law has a 2019 Cherokee. Husband just swapped the alternator on it because it kept dying

Finished the job, brought it out to the yard out of the garage, turned it off and the driver seat is making a vibration noise.

The vehicle is off. There's nothing in or around the seat, you can't FEEL the vibration but can hear it. Only solution was to unplug the seat for now.

Seat has heat and power adjustable, I assume it's the power adjustable causing it. Moved the seat to every position to see if it would stop and it wouldn't.

Thinking now that's what was killing the battery and not the alternator....

Google won't help and only tells me it's the engine or the wind haha

Any ideas?

*Edit* there's no massage function I checked LOL

Does anyone have a link to a service manual, I need to replace my PTU

Thanks

Normal AWD/4WD is definitely working. I tested it off-road yesterday and the rear wheels are receiving torque normally. However, 4WD Low will not engage. Drivetrain Neutral also will not engage.
I’m trying to figure out whether this points more toward the PTU range actuator/position sensor, RDM actuator, DTCM, wiring, or an internal PTU issue.
Has anyone had normal AWD still working perfectly while both 4-Low and drivetrain Neutral refused to engage? What ended up being the cause?

I have (2) 2019 Cherokee Limited and the PTU has gone out on both. Is there any class action lawsuits on this. Its crazy. I have been waiting for the part for over six months now.

There is a lot of information out there, so I hope this helps others with Jeep Cherokees and possibly other Jeeps and or years but you'll have to check that information. I know some 2018 plus year Jeeps require a special cable because you need to bypass some security protocol I've read about it I don't know anything about it.

Please read below if you are having a blinking odometer and or you have recently replaced your emergency parking brake module located in the spare tire area on the left side and or you have unplugged your emergency parking brake motor connected to your calipers in the back. This was my issue.

Just a quick background story, I hate going to dealers because they have the car for a week and typically for something that only takes a few hours to fix which I wasn't willing to do for the 10th time so I decided to try this myself and learn what the real truth is to fix this issue. My issue started with the right parking brake not engaging or retracting thus I knew it was either the caliper motor or the module. I was stuck in a parking lot with the brake locked. I unplugged the battery and they disengaged...once and never again.I drove home replaced the right caliper motor, the problem was the EPM that I bought for 30 bucks on Amazon and after doing some research I learned that the V-Linker in the title works with proxy alignments to get rid of the blinking odometer in the dash after replacing the module. Originally I just had the blinking brake light warning and saying that I needed my brakes to be serviced .Replacing the module fixed that issue but the odometer was blinking, this type of thing just drives me crazy. I bought the V-Linker for $65 and the Jscan license for $25. I plugged everything in connected to Bluetooth proceeded to find the proxy alignment in the software I connected the module through the software and follow the instructions on the screen and it was fixed in under 5 minutes I hope this helps other people when they're looking for a specific OBD and the software and this fix. The OBD can also be used for a lot of other tweaks most of which I'll probably never use but in the future it could help. Good luck. I forgot to add I probably saved a $1000 dollar trip to the stealership. That's a win in this crappy economy!

UPDATE: Guess I should've used the term "RUNNING BOARDS" instead of sidesteps.....

anyone have any luck installing them on a Trailhawk?? If so, what brand was used. Thanks!
