Hi all. I just installed my new JPro-3.8L and I was so excited to have the latest mod in my car, only to find out that the horn and AC weren't working. I checked all the fuse area and then decided to put back the old instrument cluster and the Horn and AC started working.

I'm begging for a solution here. I'm not ready to drive my car without the JPro in it and I can't drive my car without AC or a horn.

I understand what you said. To solve this problem, you can contact your store and ask them to help you upgrade your machine MCU. Tell them that you need to upgrade your 3.8 displacement MCU, so that you can solve this problem quickly. Or you can leave your email and I will send you the upgrade file, but it will be more cumbersome 😀
