No lights on a 95 dodge neon

Oh boy, I just went through this with my '92 Lesabre, took a long time to trace it all down, and wound up splicing in a new wire just to my instrument cluster lights. A short kept blowing fuses somewhere in that circuit.
Down where your feet go, up under the dash at the fuse panel, there is a 15 amp fuse for park/tail lights. When you hit the light switch (for heads or park lights), power is sent to that fuse, and then to the exterior park lights. There is another wire from that fuse (green wire on mine) that also goes up under the dash, and splices to several bulbs-on the radio, on the HVAC controller, on the ashtray light, also one to the under hood lamp, and then one to the dimmer/brighter switch on the dash, the rheostat that controls brightness of interior lights. One of the green splices goes into this switch, and then another wire goes from this switch to the instrument cluster for the gauge and dash illumination. I couldn't find the short, so ran a new wire from the park light fuse to the gray wire to the instrument cluster for the cluster bulbs. I bypassed the dimmer, and left off the HVAC bulbs and ashtray light. Too much trouble to wire them all up, and think my short may have been in the dimmer rheostat.
If you have a voltmeter, pull out the dimmer switch and check for power on those wires, the green from the fuse. The park light must be switched on, or the fuse has no power. There be 8 or 9 wires on that dimmer rheostat-I never did figure out where all of them went. Asked all over a Buick forum, but nobody had an answer.

Did you check for voltage at the 50 amp fuse circuit. Even if the fuse is good if no voltage on the fuse circuit, the circuit is still dead. There is a light green wire that carries voltage from headlamp switch to dimmer, is that wire hot with headlamp switch on?

There are wiring diagrams for free, just about everywhere, if you don't have one. Autozone .com has free wiring diagrams on vehicle repair guides link. You have to register your vehicle, year--make--model, all that good stuff. It's free.

On most modern cars, the dash lights, tail lights, and headlights are on different fuses, but are all controlled by the light switch. Check the fuses first. If all are blown, you have a major wiring problem, a short. If they are not, the problem is probably in the switch.

something in the wire setup has gottn wet and caused it to short out . i would recomend ordering a new wiring harness for the engine compartment. and when re connection everything use di eletcritc grease in them so they will not do it again.

Typically this can be caused by a bad fuse,bad dimmer switch or a poor connection to the dimmer switch due to wires fraying or terminals at the dimmer switch melting.

It's possible fuse but not likely. Sounds like you dimmer switch (lever to switch between his and lows) has gone bad

Check the fuses. You may have a couple blown out. There is a set of fuses under the bonnet and another set of fuses under the steering wheel.

there could be a short somewhere in the wires

Well, check the fuse box in the engine compartment...then check the fuse on your side panel at the end of the dash...last place, Flashers are located either on the bottom of the fuse block or on a module under the dash. They are replaced by simply pulling them straight out. Note that the prongs are arranged in such a way that the flasher must be properly oriented before attempting to install it. Turn the flasher until the orientation of the prongs is correct and simply push it firmly in until the prongs are fully engaged.

The dome tight is actually a combo fuse/light. If that light is burned out; 1 the locks won't work, and 2 the odometer will flash "FUSE" and 3 the "DOOR" warning light will stay on - try replacing the bulb. If it stays on with all the doors closed, more then likely one of the switches that are built into each of the door latches is not making the correct contact to shut off the dome light/dash light. The correct fix is to replace the defective latch. The other option is to just cut the wires that feel the switch inside the door - then the car will think that door is always closed and the lights will not come on when you open that door.
