i have a 1999 dodge ram 2500 diesel and my interior dash lights don't work and i have checked all fuses and are good but when i put the dimmer switch up to high i blows my parking light fuse. i bought a new interior cluster it didn't change anything so going to return that. I do have 3 lines on the back were taped into by last ownershere they are solid black with yellow strip and solid pink with red strip and brown but no new wires going to them now. very frustrated with it might talk to dodge dealership to get a wire diagram printed out figure out what is going wrong.

Sounds like they had gauges. Now i would have to be there to see what is going on but i can help you with the wiring diagramsWhat fuse are you blowing and do you loose blinkers too?

blinks still work when the fuse blows but when i put a new one in the park lights work. i have gauges installed right now but they just got a fuse tap on the cigarette fuse number don't know which number that is again but ill look tomorrow.

i will post pics of what it looks like tomorrow to help out on what i am saying

Looks like fuse F. From what i see it runs the lights to cluster and radio. Also to your switch and to the turn signal/ park lights
