Help! I broke my Jeep!

[ChuckMalone]

Hey everyone. A few months ago, I upgraded the stock radio in my 2021 Willys Sport to the 7" one. All good there. I thought it would be a good idea to upgrade the HVAC controls so that I could use a volume knob, etc. Bought the correct part, got the OBD2 thing, the cables, downloaded J-Scan. This morning, I put the new controls on and for the life of me I couldn't get the temperature to adjust. It only blew cold air. The heat wouldn't work.

No big deal, put the old part back on, reset it to single zone MTC on JScan. Well now not only do I still have no heat and can't adjust the temperature, but there is an incredibly LOUD fan noise coming out. It's never been there before. Can anyone help me out here? Thank you!

Just checked J-Scan for errors, there is a new error: U0184-00 lost communication with radio

If I remember correctly, there’s a bunch of different settings for the HVAC controls in the Jscan. Make sure you have the right one for your vehicle, dual zone, single zone, etc. if it’s not the right one, it will not work.
