This is strange!
I hooked up my gauge and the light worked including the dimmer.
Now my light doesn't even come on nor does my test light at the back of the headlight switch,but the factory dimmer on the dash works.
Anyone else have this problem?

 

Correction:
My clock and odometer lights work, but not my dash lights.

 

does anyone know?

 

Check fuses. How did you wire gauge up? You saying gauge lights dont work nor the dash lights?

 

I tapped into the back of the headlight switch.
The dash light or gauge light does not work.(same wire)

 

Ok. So is there power going into the switch and just not coming out for that wire. Or is there no power going into switch. Which colored wire did you tap into?

 

Ok i went and looked at the wire i used and since your truck is an 06 like mine i tapped into the orange/black wire. The test light should get brighter and dimmer when adjusting lighting.

 

I thinkit was the orange/brown wire, but anyway it worked yesterday but not now.Also the dash lights quit, so something happened.All the fuses appear to be good.I hope it's not 1 of those things where you have to go to the dealer and reflash or something crazy like that

 

Nah it sounds like maybe the switch is no good. I would definitely check for voltage at switch. Do headlights work. What works and what dont?

 

Here's what works
headlights,parking lights and rear cargo lights.
Here's what don't work
dash lights and dimmer function

 

OK so if theres voltage going in and not coming out. I would say theres a switch problem. I would check all wires you hooked to gauges, maybe something shorted and caused that part of the headlight switch not to work. Just hope you didnt fry dash lights, cause i would imagine a new cluster would be pretty expensive. Im going to look at dodge service cd i bought and look at wiring diagram.

 

I already looked and I might have to buy a new cluster!

 

Yeah you were right its a orange/brown. Its dark here and i was using a flashlight looking under dash. I wouldnt rule out the switch. If you got a friend with the same truck as yours unhook your gauge wire from your switch and try his headlight switch. That might fix it. Cause if theres no voltage on that wire that means no voltage going to your dash lights. Just my .01

 

I don't believe there's voltage going to the switch according to my test light.I wonder what might of caused a short after I had it working?
Oh well, Ive seen some crazy stuff out there.
