Hello, i have a 2019 ram 1500 classic express. I am in the process of doing a full interior upgrade (katzkin seats, cluster, headliner, dash, ect). I have everything except an hvac module for the 8.4 radio and i have seen some people say they didn’t need it on other forums. Will i need the module? I have factory 7 speed fan

Yes you will need it if you plan to use the 8.4 HVAC bezel that surround the radio and the radio controls on that bezel.
