    I'll be doing this mod in the next mont or two. Got all the parts sourced, just waiting on a break from work to get this done.

    Hats off to all of you doing this. I would love to have it because the little woman drives me nuts. She wants heat on feet I want front facing heat blowing at me. We fight all the time over it but damn this looks crazy. I’m fairly handy with simple stuff but yikes.. The thread starting post had me stressed just going thru the pics and description steps. I had to stop looking thru it after the part where the dash was off.

    Disconnect anything and everything then pull the whole dash and steering column an whatnot out. WoW. THEN hope to God it all goes back together!. You get it all off and after halfway putting it back together you realize you forgot something. I couldn’t do it just worrying about something like that happening.

    so.... just want to say to anyone who successfully does this mod, I am impressed and I know this is a pretty intensive mod and anyone who rides in your truck and enjoys the fruit of you labor, will never truly know what went into it so just want to say “Way to go!”

    :peace:

    Lol it's honestly not that bad and it's relatively inexpensive to do. If it makes you feel any better the Dual Zone system only controls driver and passenger side temperature. You cannot change the air direction from side to side. If you have it blowing out the dash vents on your side she cannot make it blow from a different area on her side.

    Good luck, let us know how it goes or if you have any questions. Remember use only OE blend door motors. I had issues with the aftermarket brand communicating with my truck when I originally did mine.

    I was able to source a complete factory dual zone EVAP assy. from a donor truck (2016 1500 sport). I discovered some minor incompatibility's but nothing that can't be overcome w/ no additional expense. Mike set me up with the additional blend door option in the HVAC harness. Just need to get some free time to get this done.

    oh ok. I thought you can select different zones like feet on one side and front facing vents on the other. Didn’t realize it just controls the temperature for each side only.

    Just an FYI for some -

    I have a 2015 RAM 2500 Mega Cab with full center console. I reached out to Benny with allmoparparts.com, and he came up with this part number 68197463AC. This part is anywhere from $300-$400 shipped, depending on the website.

    Anyone else know of a cheaper part number that would work, confirmed? I know RAM says a lot of parts are not interchangeable, but we know they are. I was thinking I was going to spend like $80 on this Distribution Housing. I might have to put this on the back burner for a bit.

    Thanks
