2001 4x4 Auto No Dash, Running, or License Light Revisited
Ive read 15-18 posts on the no dash, running or license lamps working so here goes my scenario:
2001 4x4 auto 4.0L
No dash, running, or license plate light on in the "normal" 2 positions of the headlight switch.
headlights, brake lights and hazard/turn signals work.
No fuses blown PDC #19, JB #6 & 7, or any in either fuse panel.
Headlight switch plug was melted, so replaced headlight switch connector and headlight switch with no change.
If i pull switch back with light touch, i can get all lights to come on in 2 "abnormal" positions of the headlight switch.
Bought yet another headlight switch and ohm'd out circuit for running/parking lights. No connection between battery + spade connector on switch and parking/running spade connector, except those 2 odd abnormal positions.
there is an aftermarket radio, but not hooked to dimmer.
Bypass switch, and all works well. Its like the switch has detents that are in wrong places. Again, no blown fuses.
thx for all ideas & suggestions!

Wow. When you bypass the switch, you are jumping 12v to the wires for, say the running lights, they work correctly? And the other circuits behave normally?
If that's the case, all I can suggest is lousy aftermarket switches that are defective out of the box.
It would be nice if you could find a known good switch to borrow for test purposes.

Installed known good headlight switch, and nothing.
Does anyone have a wiring diagram and connection diagram for a 2001 Jeep Cherokee headlight switch? Everyone I've seen on Google is from an older Cherokee or a Bronco, etc.
My OEM headlight switch has 9 terminals labelled U, B1, B2, B3, P, H, D, I, and possibly a 5.

Any chance the problem is in the wiring harness connector that plugs into tbe switch? Im no jeep expert, but i think back to my old f150 and remember they had some funky problems like that, everyone thought was switch, until they pulled and found the connector burnt or melted. Wondering if there's something similar here, possible bad connector.

"Headlight switch plug was melted, so replaced headlight switch connector and headlight switch with no change."
Its just weird that if you just slightly move switch pull past detent, everything works just fine.

Bump for an update
I have been having this issue for a while now where the running light will work between the detents. Have you come up with a solution for you problem?
