2022 3500 Rambox drivers side lights out

[cjm368]

Good Day,
Trying to track down why the drivers side rambox lighting is out. Tested the switches - no power to the contact switch. Passenger side, and box lighting both work fine.

Does anyone have a wiring diagram for them or suffered similar issues?

Thanks

Mine did that but it was the upper rear switch as it was sticking. I lube it with dry lube and it seems to be fine for few months.

Thanks - I tested the switch - there isn't any power to it

I am assuming that you have a fuse out. Do you have a multi meter to help find it ?

Hi, I have checked all the fuses. I've now got the wiring diagram from Ram...it seems that they are all run off the interior lamps circuit... and given that the right side are working, it can't be as simple as a fuse.

I'll start tracing down wires to see if there is a break somewhere.

Thanks

I use this meter as a diagnostic tool to help find stuff. They are sold by multiple on line retailers.

Wires can be broken internally and not be at all obvious from the outside.
