2001 jeep cherokee sport 4dr 4wd headlight switch acts funny I have replaced it with a new one and have same problem...no dash lights or tail lights if the switch is fully engaged (headlight on position) if I play with the switch and balance between parking light position and off I can get dash lights and parking lights to come on. Any suggestions?

Could be a bad light switch or relay, but I'd check dash and body grounding first. On every Jeep I've ever owned, I run a direct ground to everything before I even drive it. To do this, Attach a 12ga or larger wire to the battery ground connector. Run that wire around the firewall side of the engine bay, removing insulation at several points and attaching the exposed wire to the firewall, (using short, self-tapping screws) both fenders and ground points for the computer. I also attach one additional leg which runs through the firewall (careful not to drill through anything important) and attaches to the metal frame of the dashboard. I also add a second ground wire directly to the engine block, eliminating any possibility of a poor ground anywhere. It sounds like a big job but it's not, and doing this precludes many frustrating and unnecessary problems down the road!

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

The problem is with the connection from the light bulb holder to the socket that the bulb and holder go into. I believe on my 01 JGC it was the top light that was going out when i applied the brakes with the lights on. If you remove the light bulb holder in the tail light assembly and look at the area that the bulb and holder came from either the metal that makes contact with the holder for the bulb is depressed, or in my case it was cracked. You can use a small flat scewdriver to lift the metal in the tail light assembly, or as i did, i just put some tin foil on top of the metal, then reinstalled the bulb and holder ontop of the tin foil (this makes the elec. connection). seems like a rigged up solution, but made sense to me, and worked!

Look for fuse panel left side under dash board, the same fuse that controls dash, is on the center, if fuses are ok go to tailgate remove panel and look for a green wire on plate light has to be disconnected, do not connect that wire ever, and look for any disconnected wire in between, I am sure that Your fuse is of
