94' Jeep Cherokee Conutry 2wd Dash lights not working

most dash lights can be dimmed or switched off check this first, then trace the wiring from the switch to the dash lights for a bad connection.

Did you check the dimmer switch for the dash lights ?

Click on the link, check fuse f13--20 amp. Not only check the fuse, check the fuse circuit for voltage, use a test lite, hot all the time.
You have to test when problem is ongoing. The fuse is for brake lamps.
At the moment, I don't know if trouble shooting one system will fix the rest? With multiple issues, I pick one system and trouble shoot.

Replace the turn signal switch. They started running all the lights threw it. They call it the multifunction switch now.

Exactly which lights do not work on your dash? Specific warning lights or the dash illumination lights?

the tail light fuse but check ALL the fuses

all the lights or just a portion of the dash?

You have all the fuse locations. I have seen some that after radio was put in did that. usually it turns out that re-grounding the dash or using different power supplies for the radio has corrected it. otherwise, I'd check the light switch and make sure it's OK.

check your fuses under dash use test light ground it, your doing negative test ,test light on, fuse ok.
do that each of them you must turn your keys on don't start the car , in order to check.. good luck!!

this is a fuse I honestly believe check them with ohm meter. Lots of cars if you have a tail light out the dash light will not function also. I hope this helps
