So I returned my old switch and bought new one. Still same symptoms. Can anyone tell me where some of the factory grounding points are? Elec. gremlins are kind of a b*tch. Need to get my old girl back on road. Borrowing 06 6.0 PS ford till I can and it feels like I'm cheating on her.

That doesn't make any sence. that the lights a working if you play around with the switch. unless something is loose. Did you ever find the ground wire that goes on the spade on the switch? It has a Black connector on it & black wire. its by itself under the dash

Yea its really wierd. running lights only come in in some odd sweat spot but if you cuntinue to pull switch out it goes out. I did find that ground. the metal bracket on the front thats bent in way that it goes behind as well has a couple spade tabs on it that it was connected too. I connected it to the metal housing on switch to see if it made a diff. but nope. Is it possible that when I'm plugging new switches in its burning them out with a spike? But the fuse is fine and gets pwr. I just hope its not wiring harness. Nothing looks as though its "burnt" or even got hot.

If the fuse is getting power now, and wasn't before like you said, check the fuse again. Also check the wires on the back of the fuse panel. I had some wires work there way out and mine did the same thing, new headlight switch and fuse after it kept blowing it, was shorting out.

Talked to my friend at the dodge dealer. Told me he added a relay kit to some of thess trucks for the running lights. He said he mostly did it on the 2nd gens but has done it on the first gen trucks too. Was done to stop headlight switch from burning up when towing trailers. May or may not be ur problem(s). He told me the relay should be behind the headlight switch. If it was installed at the dealership

all of my wireing looks brand new! same with the switch! even if the switch was bad tho would the blinkers and brake lights work along with the head lights? because i have no power to the parking light plugs but when i hit the blinker it will get power! its driving me crazy! think im goin to pop in a new switch anyways to see if it dose anything

To anyone interested or following my little running light elec problem. It turned out the head light switch has 2 pwr supplies to it. owners manual only says the 3 amp fuse but there is also a 20 amp fuse that sends pwr to rear half trk. Fuse was not blown but looked broken. One of my license plate lights looks like it got real hot but cant seem to find what would cause anything to go bad like this. Either way the old girl is back on the road and lit up!
