Promaster has 2 fuse boxes. It’s a 2023 1500. (Different years are apparently different.)

One is on lower dash by drivers knee. I haven’t had to deal with this one yet but it’s easy access.

This post is about the 2nd fuse box located, basically, under the driver side head light assembly.

This external fuse box cover is fastened down with 3 screws and one of them is located directly under the head light assembly and is an absolute PITA to get to.

First the Promaster manual only tells you about the 2 obvious & easy to get to screws so one gets to spend ALOT of time getting frustrated trying to remove the cover because it’s still held down at one corner by a screw you can’t see, don’t know about and is practically impossible to get to because of said headlight assembly once you finally have concluded there gotta be a 3rd screw holding that EFFING COVER ON!

WHEW!………

Above pik: problem screw is colored yellow, center right under headlight assembly.

Anyway; after almost 45 minutes I finally got the damn cover off without breaking something - intentionally or not - and was able to remove the blown fuse that is paired to the inside dash 12v plug that initiated all of this.

Needless to say the “third screw problem” has been forever solved by not replacing it. 2 is good enuff.

O might be inclined to reinstall that screw for one reason. The Promaster is know for what getting into the engine compartment when it rains of you wash it. There's 2 drains on each side of the plastic cooling that get plugged and/or can't handle the water. That ELECTRICAL box gets soaked so that 3rd screw might help keep it water tight.
Water also flows in smack bag in the middle section because that cooling is 2 pieces, over lapping in the middle which doesn't work at all.
When rain is coming or I wash mine, I place cardboard deflector over the box and the bulk of the motor. Check out the top of your engine after a rain to see what I mean. Very know issue that all have

Also, I really like the positive and negative connection point under the hood to jump or charge up the coach battery since the placement of the battery is not easy to get to being in the floor 🫨
 
I considered the possible water prob but……

That fuse box actually has 2 covers. Once one finally is able to remove the cover that is screwed down by not 2 screws but 3! Three! Count them RAM! You put 3 screws on it! not just 2 like your manual instructs……

…….you will discover a 2nd cover that actually covers the fuses. It is easy to remove and you will discover………FUSES!

Sooo to summarize:
there are fuses under a cover
that is under a cover
that is under a headlight assembly
that is under a hood
that is part of a van
that Ram built.
(somewhere)

Yep. I’m not replacing that 3rd screw under the headlight assembly.

EDIT: I will wrap that fuse box in a piece of gortex material b4 I reinstall that 3rd screw 😎

Yeah; the battery placement not being easy to access simply makes up for a fuse box that isn’t easy to access which makes up for an oil filter that isn’t easy to access either……..

Just move out in the deserts where it doesn’t rain much and when it does throw a tarp over the whole thing. Better yet just park it permanently so you don’t have to do as much maintenance. Then get an economic means of transportation and after you are gone leave enough funds to have it hauled off! Lol!!! Worked for me!
