Hello I have a 2018 ram 1500 express and am in the process of converting over to the 8.4. I have the 8.4 and the hvac dash panel with 7 speed fan controls. I know that i need to buy the HVAC control module and harness. Do I need to get a new blower resistor as well?

Your express should be 7 speed already on the blower so I believe you are good. An easy way to tell, count the number of fan segments painted/depicted on your factory blower control knob.

What you need depends on your truck model, fan speed, original radio setup & features and what radio you're trying to install.
Sent you a message with details to get this started and get you squared away.

Yeah, with regrets... They still haven't mailed it and not responding to messages :(
You could always cancel the order, contest the charges and buy from @Mpgrimm2 . He responds before and after purchase (and even without a purchase because he's a forum member first)...good people.
