Head light switch or wiring is shorted out, that is all.

i figured that it was the switch but im running into problems removing the switch. i cant get the knob to ome out to take the plate out to remove the switch and i ant get to the back side of the switch because the ac vent tube and wiring

I think the switch knob has an allen head set screw or something similar. You could test the switch theory by back feeding 12 volts into your running lights circuit, however this action could cause you more headaches by frying something like what switch you have left. But you really should not be hurting anything to tell you the truth, but shctuff happens, lol.

Chances are good it's a headlight switch. Unhook the battery.
To remove the knob pull it out till the headlights are on and find a button on the switch under the dash. Push the button in and pull the knob the rest of the way out then remove the retaining coller with a large phillips screwdriver.

If you pull trailer much wire in a relay to the tail light system or seperate the trailer lights from the system.
The replacement switches that are avalible from the parts stores are junk now days.
I find Dodges in the salvage yards with factory switchs for my replacements most aren't india or mex junk.

i figured ot the problem.the conector on the harness for the lght control switch likes to melt and it looses contact. i did m share of research and found tha this is a problem manly with the first gen dodge duallys. i guessit has to do with the extra light on he cab and fender running off of the small guage wire. i appreciate the help.

Relay the lights and your switch wont burn out anymore. And the lights will get a full 12-14.4v not the 9-10v they get through the stock headlight switch.

I had same problem. No dash lights. no running lights. but brakes when applied, and headlighst. turn signals worked. Replaces dimmer switch. Turns out there is a fuse sending pwr to switch that isnt stated in manual as relating to that circuit. Ill have to check what number. but it was ok( not burnt) but broken. had to be removed to tell. so go through the high am fuses and check the no brainers first. I tore dash off checking and replacing stuff before a friend found this from cutting OEM dimmer block open and seeing it uses 2 sources for pwr.

i went through and changed all the fuses and checked and changed all the bad bulbs before i started tearing into the dash. what it is doing is melting the plasti onto the terminal and it is not getting contact. i found it on another site and its mainly the dually that has the problem with the melting switch because the small guage wire is running all the extra cab and fender lights
