Too many things going on at once to point you in any one direction besides saying to really scrutinize your harness.

Do you have steering wheel Audio controls? If so run the radio without the original controls/Bezel to verify it.

Get another HVAC module (what's your PN on it) and see if it's that. If not look at the harness again. Could also be a bad bezel.

I have re-ordered bezel. Hope that is it. I am not confident about the harness. I used work with microboard long time ago but it was long time ago and I have bad eyes now so I had to use magnified work cradle. So it could be the cable. If new brand new bezel don't work, I will purchase the harness from you since AC module was new in the sealed Mopar Box.

You can also send me your bezel to test if you want to pay shipping both ways.

Got my wiring harness for my 7 speed fan, 8.4 upgrade. Professional work, looks amazing. Installed and no issues this far.

Would highly recommend M2mods

Hi. I recieved brand new control bezel. Everything from touch screen works but still no power to the bezel itself. So as you said before it is likely the DIY harness I made. I need to buy your harness. Would you let me know how to order?
Thanks.

Hello Mpgrimm2.
I have found the problem accidentally and luckily have fixed the issue. I could not able to do this without your help. :)
I truly appreciate your help and respect your effort to help others like me. You are awesome! :):)

Tip - If you get the Red banner message about the "cellular radio needs servicing, see your dealer" even with the plug from M2Mods or an antenna connected, check the cellular antenna jack on the back of the radio. I recently received a VP4 radio from an auto recycler and the center pin was bent against the outer barrel. The plug from M2Mods went on and clicked but I kept getting that error message. I was able to straighten the pin with a very small screw driver and the radio works fine now.

Going to share this here for now ....

* 14-18 ram 1500's have a variable displacement compressor (typ. associated with the 7 speed fan)

>> 14-17's w/RAx = 68268186Ax * HVAC module (or superseded PN below)
>> 18's w/UAx = 68366552AA HVAC module

* Here are all the compatible/superseded 14-17 ram 1500 RAx HVAC modules from post 2....
68268186AA, AB, AC, etc
68183973AA, AB, AC, etc
68236772AA, AB, AC, etc
68239172AA, AB, AC, etc

------------------------------------------

* 13-18 ram 2500/3500's (& 13 Ram1500) have a fixed displacement compressor (typ. associated with the 4 speed fan)

>> 14-17's w/RAx = 68105017Ax HVAC module
>> 18's w/UAx = 68366553AA HVAC module

& the current thinking is to match the HVAC module to the 8.4 radio year.

I wanted to take a minute to thank @Mpgrimm2 and @DeereGuy for suppyling the Base to 8.4 Radio Conversion Harness (7 speed Fan specific models), ATC Temp Sensor Add-On w/conversion harness, ATC Humidity Sensor Harness and 2018 Security Bypass Harness. They work great and I will post pictures on how I did the 2018 Version of the upgrade.

All this information is making my head spin. I've been reading and trying to understand the threads but it just brings up more questions.

Where I am:

2016 Ram Express
- RA1 radio
- Backup Camera in rear view mirror
- 7 position fan
- 3 button controls for HVAC in bezel (stock)

Where I want to be:

2016 Ram express
- 8.4 4C UAS (If I come across a UAQ radio OK) to support Android Auto
- Backup Camera in radio screen ( old eyes and that screen in the rear view mirror view don't mix)
- 7 position fan
- Single zone HVAC.

As of this moment I only have a single zone bezel. Picked up at a local yard.

I plan on cutting to fit the USB hub and use ABS plastic sheet for fitment..

I'l locate my own radio but need to purchase the appropriate wiring harness and HVAC control module and USB hub to make ti work.

With all the variables out there and the multiple ways others have done this It's kind of "Mind numbing" and locating and swapping parts until I find what works isn't an option.

I'll continue to read and try to understand but if I could get some assistance to 'cut to the chase' and get me started I would appreciate it.

I sold a vehicle with an android capable system and want to get back to it.

I'll send you a private message/conversion shortly. If you reply back with your phone number I can give you a call today to cover any questions you have and get things started.

I just wanted to thank MPGrimm for the conversion and the awesome customer service. Ive had the conversion in since January and its awesome. The directions were very clear and even when I had questions, he responded quickly. The wiring was very professional and looks like the factory wiring. It also came in the mail very quickly after ordering. I highly recommend him for any of the services and products he offers.

NICE WORK!

Why is the Single zone climate controls preferred over the dual zone?
See post 15.
Basically to avoid unnecessary/inop buttons.

Single zone ATC can be done (with/without custom bezel) or full dual zone ATC if your willing to tear out the dash and replace the plenum box and wire in extra blend doors.
