The only thing the parts guy sees when he looks up the vin of a truck, is the part number that was installed when that truck was built. Itís not his job to guess if some other part number will work. He can look up a part number, and all it will give him is a list of vehicles and a list of sales codes associated with that part number, but itís too confusing for him to be able to tell a customer for absolute certain if itíll work on your truck. Thatís why the best thing to do when youíre making upgrades and ordering parts, is to search auto trader for a truck that is equipped with the option you want, and give THAT vin to the parts guy.

3) It would cost $14,000 to repair my out of warranty transmission.

Have you ever heard such BS....geez!
The rep told our parts guy they're physically different and would likely have to paint the doors.

Anything else is just a matter of how they are configured via sales code by the dealer, or by setting them with AlfaOBD. You can take the door modules out of a Durango or grand Cherokee, and configure them for our trucks.
The door module part numbers you posted support power folding mirrors.

I have a friend whose 2017 has a 68233219AC door module (I can't remember which side that was, I think driver) for the fully loaded tow mirrors, and that P/N door module has since been superseded by 68286791AA.

The supposition is that if you have any of the fancy options, your door modules should work with all of the fancy options, so long as the correct sales codes get flashed into the BCM, but I have no direct confirmation of this. The door modules are pretty inexpensive compared with the mirrors themselves.

There are work arounds, but I just want to know what the issue is. There is apparently a part number that will work from FCA, but it's not being manufactured till at least March (originally they were hoping for November). A big online Mopar dealer says they will work, another said they can order the modules that will permit the arrows to work correctly when flipped out (I'm not too concerned with that, but it would be nice).
Yes, I did end up getting the OEM tow mirrors black with power adjust, heated, puddle lights, turn signals, memory, and power fold with the ambient temp sensor in the driver side mirror.

I have not flashed the BCM yet for the power adjust switches to work in the proper orientation when flipped-up, but I just haven't gotten around to it and they are not hard to operate the way they are. It is on my to do list.

The passenger side mirror takes a little getting used to when flipped down because the convex mirror is oriented vertically versus horizontally, but they work great when flipped up, especially when towing my JKU.

The part numbers for the mirrors themselves are:
Driver - 68412885AC
Passenger - 68412884AC

The reinforcement brackets are:
68078242AA & 68078243AA

I bought the M6 half hex rivet nuts from Amazon, and the M6 flange bolts from the local Ace hardware.

My truck has the following sales codes as delivered:
LEB - turn signals
LEC - puddle lights
LEM - memory
LER - power folding

The corresponding door modules in my truck are:
Driver - 68225103AC
Passenger - 68225102AC

As mentioned above, I haven't had the chance to get the LEG sales code flashed into my BCM yet, but my dealership tech friend said it was an available option for my truck on his computer when he ran my VIN.

Hope this helps.

Loki223 @murderman I just sent you a PM with my VIN for your buddy to run to see what codes are listed on my truck, to compare to yours. So he should be able to see what needs to be changed
11-08-2019 01:52 PM
Loki223 My 18 has power fold, memory, and are towing mirrors. not sure why they are telling you that those options aren't available when they clearly are. I'd say get them, install them, add the tow mirror sales code. and be done with it

RedFox1 My 08 3500 srw doesn't have tow and I plan to upgrade also. I don't understand why they would make any of these 2500 3500 diesel trucks without tow mirrors.
