high beams
 

ok im kinda a noob im 17 and just got a 1990 4.0 cherokeee yesterday and i have no high beams, interior lights, rear running lights, or lights on my gauges i havent had a chance to check the fuzes yet but i just wanted to go on here and ask what your guys opinion is

If you have low beams and front parking lights, but nothing else, I'm inclined to think it the switch.

Be sure to check your fuses and verify that your bulbs aren't burned out.
