Headlights work, no dash lights

Was backing up out of the garage this early evening and all the lights were on when suddenly the dash lights all went out at once... Headlights and taillights work as does the blue high beam indicator on the speedo.
Checked the fuses and they seem to be okay... could it be the light switch gone bad?

Try turning the headlight knob. It may just be the rheostat playing up.

If that does no help you need to break out some test gear. A 12V test bulb with some long leads is a cheap and dependable tool for this.

The voltage goes from the headlight switch to the fuse box IGN LPS fuse and then down the orange wires to backlight the gauges.

same thing happened to me last night. All of my exterior lights work as well as my brake and 4wd dash light and floor lights but my dash last night have worked since i bought the jeep a few months ago. Somehow my dash lights all cut on 2 days ago. then, yesterday after drive, i went out to take a look at the dash lights since it became night and they didnt work anymore again! I tried moving around all sorts of wires and adjusting the light knob and moving the dimmer switch and all sorts of stuff. It also was raining yesterday when i drove my jeep with the bikini top. While my light switch is new, the receiver that plugs into the switch is pretty beat. I think that may have something to do with it. its even melted in some spots. As I will do, try checking your ground for sure, seems to be the go to for most people. Mine is on the bottom inside lip of my dash right behind the drive side speaker slots. Not sure it they are all like that or not. dash is also supposed to be grounded to the frame somewhere.

Well, I had a replacement light switch and tried that and same result. One thing I did notice though, the park/tail fuse keep blowing as soon as I turn on the lights.. Is this a ground problem and where should I look to check ?

Was this a new switch or just one you had laying around?
There were two headlight switches, make sure they are exactly the same.
One has a jumper, one has not.

Grounds do not cause fuses to blow. A fuse blows when there is a short in the hot side. Your dash lights are on the same circuit as the taillights.

I checked my headlight switch and they are both identical... When the fuse blows, I lose my taillights also. This is really odd, I did nothing crazy to perhaps incite this.

Any other ideas? I have gone through 8 fuses trying different things. I even disconnected the front light harness on the firewall to eliminate that. Still blows.

Found it! (I think) Removed both tail lights and unplugged the harness going into them.... Inserted another fuse and I have dash lights and nothing blew! Now I need to either clean up the lights or get some new ones.
