I have a 2024 Ram 1500 tradesman (6 lugs) with a 5-inch radio, and I want to upgrade to an 8.4-inch radio. I have purchased a 2019 8.4 radio on eBay and a bezel with radio and ac controls. The radio works, but the ac control only blows hot air from the defrost setting. I saw online that I would need to upgrade the whole harness or purchase an AC module adapter. My original bezel only has three controls for the AC. The one I bought has more options. I posted pictures. I appreciate the help if anyone can. Thank you.![1000013757.jpg 1000013757.jpg](https://www.ramforum.com/data/attachments/536/536619-6f016fe11e5f6bc737d59721f60e88d0.jpg)
