Anyone have the issue of the wires coming to the rear doors breaking from the constant bending from the doors opening and closing? I've lost count of the times these have had to be spliced back together. It started with me on one side the doorlock quit working and rear defrost wouldnt work... the other side was the tag light wire...

Mine doesnt look like that.......yet! I have a 2014, have they improved on this obvious flaw in later models?

We have had to replace, under warranty, the passenger side rear door harness. The loom broke just like in Dwight's pic, but we spotted it immediately, thankfully, before it was pulled out like his, or F'up'd the door before we tried to close it.
We did a "patch" on the broken one with a larger guage of loom, and some black Gorilla tape to reinforce it. Then, we looked at the other side, and decided to do the same reinforcement to it before it broke, and did the same to the new warranty replacement. You must be careful not to interfere with it sliding into the door pocket when nearly and finally, fully closed. It may not be pretty, but ours is a work van, I'll go for tough and preventative first, looks second. And I don't think it looks "that" bad anyway. Trying to attach pics.

It is a flimsy design. I wrapped electrical tape around the spot where the loom hits the connector on the van and it has held up. One of our looms came off the spring track within the door and was kinking every time we closed the door. If yours is kinking, you might want to open up the door by removing the plastic panel and make sure the loom is still attached to the spring and running smoothly.

I have 2 promaster 2500's & both are broken on the driver side rear doors. One is a 2014 159" WB with <10K miles on it & the other is a 2015 136" WB with 30K miles on it.

The 2015 broke first & the contagion passed to the older, but less-experienced cousin. I dread going to the dealership for warranty repair, but that's where the 2015 is heading next week. Gorilla tape therapy will be standing by for post-surgical therapy.

My license plate light wires kept breaking. I finally ran some high quality speaker wire in to replace the brittle stock wires.

Hi guys,
Reviving this thread as my new-to-me van has both doors messed up.
Trying to find the part number so I can just order it from an online vendor rather than going through the dealership.
Anyone got a part number? Could only find electrical diagrams but nothing for the latch and loom.

For future guys looking at this, my easiest fix was to go to my local junkyard, and pull the wire loom assembly from another PM.
In the pictures is the broken wires, the pick, the install, the plugs, the finished product.
You have to take the entire slide assembly off, but it's only a couple plugs and a couple pinch clamps on each door.
Super easy fix, but couldn't find any new parts.

Thanks for the photos, MountedForAdventure. If you look above, try my "reinforcing" addition. It's helping us nicely. I haven't changed a set myself yet, just warranty at the dealer on one. I see that you accessed the D pillar post end through the hole after removing the tail light assembly? Thankful if so, because my upfit makes accessing from the interior difficult at best. Equipment and shelves on both sides interior, and we insulated and paneled over the holes before the equipment went in anyway. Glad to see I can access the D pillar ends from by removing the tail lights, if I'm reading your pics right. BTW, we use the shi! out of our rear doors, so trust me, our reinforcing method is helping immensely. Going in to our 5th year on our 2014. Dealer did their replacement on the primary passenger side door in 2015, we have repaired both current ones with our reinforcing trick once each, since, both about a year ago. HTH and Thanks for your info and photos!

You probably can, but I came in from the interior. There are black panels that cover 60% of the D pillar inside, remove them and everything is right in front of you.

Andy, check out your local wrecker to see if they have an assembly. Every comes as one assembly from the plugs in the van to the plugs in the door.
