Am I missing something or is everyone answering the wrong question?
If I am reading this right you are having problems in your instrument cluster in your dash not being lit up on one side, correct?
If so it is most likely a burnt out bulb or two.

SOURCE: electrical problem

Find the ground wire on one of the lights and add another ground wire to a good clean metal surface and see if that fixes the problem. It defently sounds like a ground problem at one of the lights.

SOURCE: Left headlight is dim - like it has a bad ground.

i think you hit the nail on the head with the ground problem,if you remove the bulb from the head light assembly,wiggle the black wire to see if the bulb gets brighter,if it does remove the bulb and clean and tighten the ground wire end.if it does not get brighter from a wiggle,connect the ground end of a test light to the positive post of the battery and probe the black wire,test light should light,if so replace the light socket.

2003 Pontiac Vibe no tail lights, brake lights and turn signals work just fine. The dimmer switch does not dim the dash lights but does work the dome just fineand the lights for the Heat/AC are off.

The tail lights work off the headlight switch, and there is a fuse for the tail lights. Make sure the fuse is good, first, a 15 amp (blue) fuse in the instrument panel fuse block. Then, you might have a bad headlight switch.
So you DO have dash lights, they just don't dim from the dimmer switch? In the wiring diagram, there is a green wire from a "tail light relay" (in the "Junction Block-Right Instrument Panel") that carries power to all the exterior lamps, as well as having a splice to the Instrument Panel Cluster (illum. bulbs), and to the lamp dimmer, and to the radio bulb.
To do any further testing, you would need a voltmeter or a test light, so you could chase down this power loss. Good luck.

Dash, dome, map lights flicker. Even when keys are not in the truck. mirrors, pwr locks and gages not working. Checked fuses, battery cables/connection. Guessing its wiring. No clue where to start..

Do you have a 'dimmer switch' on your dashboard?

A dimmer switch allows you to reduce the power /light to the instrument gauges for night driving. A faulty dimmer switch can cause those problems you describe (I'm in the UK and drive a 1998 Jeep which has an identical problem...)

If you don't have a dimmer switch the fault is likely to be a loose bulb in the instrument cluster- the gauges, or a wiring problem in the dashboard.

Headlights wont work on dim, only bright

Check your head light bulbs, your truck has the dual filiment headlight bulbs one per side which does both high beam and low beam, 9007 bulbs.
If the low beam filiments are burned out only the high beam will work.
Also look into finding out if the headlight switch is gone bad.
The headlight module and or drl module maybe defective.

\1991 geo metro dim headlight pass side

in low beams or high or both?
that is caused by:
1: bad held lamp. old lamps can go dim.
swap left and right, if dim follows bulb, bingo weak bulb or wrong type bulb. buy matching blubs (same brand and P/n)
2: bad wiring to lamp. damaged wires, or connectors to same.
4: bad combo switch. (if low beams)
5: bad fuse or holder, corrosion , to either.
head lamp fuses. there are 2. left and right.
6: hackers, many hackers put in wrong lights. inspect it.

1998 toyota corolla dash and shifter lights out fuse and relay good

sounds like you have a bad panel dimmer control. try turning the control from bright to dim very fast a few times then slowly, do this in a dark area or at night with the headlights on, you should see a flicker of light occasionally. If you don't see any light then it could be either the headlight switch or the dimmer control, if you DO see any light, then it's your dimmer

I have installed a trans, boost, exhaust gauges and wanting to hook up to headlight switch to utilize dimming feature of the gauges. I need a constant hot, hot when lights are turned, and dimmer...

Use a 12 Volt test light and determine which wire from your headlight switch is hot when the lights are turned on and which wire goes to your instrument panel lights. When you are probing for the panel lights you can operate the dimmer to make sure the test light dims and you have the correct wire.
If you locate and hook into these two wires your gauges will operate as you desire.

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.

Thanks
Mike
