|dd4bama||OK...there's a small black wire coming off the light switch that has a rubber end on it - I see it on the wiring schematic. Is that the ground? If so, where does it go? If not, what is it to?|

|andyt86CJ||Guess I will be messing with that this weekend|

I had a similar problem on my CJ and found that first, the lights for the dash lights are typically a single orange wire harness connecting the bulbs and grounded via the dash. And secondly, the headlight switch has a very simple dimmer mechinism which is basically a contact touching a spring to create more or less brightness on the dash as the knob is rotated.
My contacts were dirty and the dimmer switch effectivly was not working. I verified that by jumping the orange circuit in the HL switch to a known hot lead (IIRC it was white) and that allowed all the lights to work but killed the ability to dim. I ran it jumped for a while with no problems.
I later replaced the HL switch and found the new HL switch dimmer circuit contacts needed to be cleaned prior to installation to get it to work correctly even though it was NOS.

|Rusty Barrels||Also check the clips that the fuse inserts into, one side can be broken off|

|andyt86CJ||no click. thanks man !|

|albinoplatypus||the switch should click once it's rotated all the way to the left. if they don't come on check the bulbs then the switch.|

|andyt86CJ||I cannot turn on the lights UNDER the dash. I just got an 86 Laredo that is near mint. My old 85 I had had under dash lights and I can't remember how they turn on. Twist the headlight knob to the left ?? I tired that nothing happened. Was going to change out that switch if need be|

|dd4bama||I appreciate that. I would like to test all of them before putting the dash back on...is there a way to ground it out properly without the dash being installed?|

|alex211||Ground out your dash, it should fix the problems.|

In your first picture of the fuse box notice the tell tale GREEN fairy dust accumulated on the bottoms of the cubicles.
Buy a can of contact cleaner and one at a tine remove each fuse/flasher and spray clean the contacts, if you have a compressor blow some air into them also after spraying while still wet to help dislodge any debris/corrosion.
That should help to some extent in general for all connects there.
While you had your light switch apart did you notice any corrosion on the contacts if so take apart again and clean same with all connects you can get your hands on, ground mounted wires also.
I took for granted when I started to restore my 81 that had been sitting for years that the wires were going to be shot everywhere. After starting to get into it and inspect most all wires were looking good for general integrity only connections were showing corrosion.
Good Luck with it.

|scooby533||Unless you can verify by tracing a wire path, NEVER take for granted a certain color is what it should be. What it "should" be and what it is are vastly different in most cases on CJ's because of PO's.|

|VACJ7||I want to say that switch has a ground wire, but you can download the Factory Service Manual (FSM) on this site and it has wiring diagrams. I would not go on faith that all black wires are ground. One of the POs of my Jeep apparently used whatever wire he had handy and sometimes spliced black wire into hot feeds as power wires. If you have a multimeter with a continuity setting you can test a wire. Connect one side to the wire and the other side to a known good ground. Mine beeps when there is a complete path. I disconnect the battery first.|
