Check the headlight switch itself. I had one go bad and the interior lights would work etc, but not the headlights. The headlight switch has several contacts inside it and it sounds like one set is bad. You should be able to test it with a meter once you have it out. Fairly easy to remove and test with any ohm meter.

I have no headlights, taillights, cluster lights and speedometer has stop working?

Have you checked applicable fuses for everything except head lamps? The headlamps themselves don't use a fuse. Check the battery junction block under the hood, one of your positive battery cables should go to junction block. If several fusible links check them. My info shows red wire carries battery voltage to head lamp switch for headlamps. The headlamp switch has two voltage circuits, mainly, one for the head lamps, for the other lamps that the switch controls, those smaller lamps are fuse protected.

Low beam fuse

No fuse, but if you have daytime running lights and are experiencing headlight trouble, that circuit could be the source of the problem. Also, in the 1999 model year headlights could be either composite or sealed beam.

Have only head lights no other lights work need line diagram of lighting circuit

The headlight gear seldom is bad. the problem is the arm on the motor and/or the connector rollers inside the motor. Replacement kits are on Ebay that fix both.
The lights not working sounds like a bad headlight switch. Riviera used the same switch so they are not to bad to find.

Both headlights are not working in 2002 Safari Van

Check both headlight bulbs, check for power and ground (the ground wire is black). If no power either wire to ground remove the headlight switch in the dash. The bezel around the cluster just pulls away. Check the connector to the switch. The large red wire (power) or the black (ground) may be burnt. Repair if possible or replace if melted. There isn't a headlight fuse. If only one setting works (eg. hi beam only both sides, no lo beam) then the dimmer switch is at fault. Its part of the turn signal switch.

Dashboard lights won't come on

Most often the tail lights and dash lights share a single feed and fuse.
Assuming you have checked the fuses (probably marked as tail or courtesy)
If you have good fuse and the head light gives a voltage out while in the 'parking light' position (usually between off and headlights) then you need to start chasing wiring.

What would cause both low beam headlights to go out at the same time? i have replaced the headlights and they still dont work.

The headlight high/low beam switch assembly.96 Safari has the turn signal stem as the high/low beam switch.Removal of the steering wheel is necessary to get to the switch assembly for replacement.

Hi there,

When you say you 'lose instrument panel', does that mean instrument panel lighting or the gauges go dead?

When you flip off the headlights, does the instrument panel come back? If it does, forget the fuse box.

If it's the instrument lighting, I'd be looking at headlight switch itself. In Safari's, the headlight switch and panel dimmer switch reside in one assembly. Coincidence? I think not.

I recommend replacing the switch. You can find one at a salvage yard for $5.00.

When you do the replacement, inspect the plugs and wiring attached to the old one for anything suspicious (loose wires, frayed insulation, bare wire, charred wire, etc.)

Let me know how it turns out.
Good luck,

If this works out for you, please take a sec and rate my solution.
