1996 Jeep Grand Cherokee Taillights fuse keeps popping

The fuse for my taillights pops instantly when i turn them on. I tried replacing the headlight switch and no luck. Any suggestions or do i have to dig through my whole dash to find the problem?

You should start by checking by the lamps themselves. Frayed wires at the sockets, pinched wires in an area where you or someone else may have done some work that may have caused a situation, where over time caused short.
I've also seen burnt out bulbs cause a shorted condition. The switch would no have been on my first to do list.

P.S.

It would be almost impossible for the headlamp switch to cause a short thats blowing the tail lamp circuit fuse, I would start with what was mentioned in the above post. Also check all the marker lights/bulbs and sockets. If you have some trailer light wiring under the rear bumper, check that too.

Look for wires that are loose, corroded, piched/chaffed on something etc. Remove the lamp/lenses and unplug them or the bulbs and see if the short has gone away.

the reason i replaced the switch was because the dash will not light up either. Sorry i forgot to mention that. i think the fuse for the dash/taillights is the same.

This problem sounds like mine.

No instrument panel or tail lamps - 7.5amp instrument panel fuse seems fine. All turn signals, brake lamps and other lamps work
