There can be several possible causes for instrument panel lights and tail lights to not work. I'm not sure I can recall all of them at the moment but will provide what I can. On most vehicles, the multiposition headlight switch controls [turns ON/OFF] the headlights, front "parking" lights, tail lights, side marker lights, instrument panel lights, and the "dome" and interior courtesy lights. Additionally, on most vehicles, when the the parking and/or headlights are ON, rotation of the headlight switch knob controls the brightness of the instrument lights, and rotated fully counterclockwise turns ON the dome and courtesy lights. Your question mentions the tail lights and the instrument panel lights being non-functional, but not whether or not the headlights, front parking lights, and side marker lights are working. Possible causes of these lights not working could include: 1. A failed fuse, but only if all the other lights you did not mention are also not working. If the fuse is good and all the OTHER lights controlled by the headlight switch are working, then the problem IS "downstream of the headlight switch. 2. A ground wire or wires not properly connected, or having an accumulation of corrosion at the connection interface. 3. A cut or broken wire in the part of the circuit which serves the non-working lights. 4. A connector or connectiors which have come apart, or have an accumulation of corrosion on their contact surfaces. 5. A defective headlight switch, or connector to that switch. There are probably some other causes which I'v left out, but these are the most commonly occuring. The procedure to correct this problem is to first visually check out [via tracing the wires leaving the headlight switch to the non-working lights] all the items I've discussed, looking for anything visually "not normal." It that produces no reason for the failure, then my next step would be to physically disconnect, and reconnect all connectors in the non-working circuit, carefully examining all of the metal contacts within each connector for signs of corrosion [remove if found] or signs of overheating [discoloration]. Either of these could cause the described problem. During this trace and examine process, also look for wires which have been cut, broken, or pulled apart. If all of these checks fail to find any cause, my next step would be to remove the wiring harness connector to the headlight switch, and remove the switch from the instrument panel for inspection and testing. First inspect the switch body and connectors for signs of corrosion or overheating [discoloration]. If corrosion is present, clean the terminal blades on the switch, and the contacts inside the harness connector. If the switch body looks "cooked" it is probably ruined and requires replacement. If the body looks OK, but the terminals look cooked, then with a meter or test light, cycle the switch through all its positions, checking for current flow. If the terminals for the non-working lights does not indicate current flow, then the contact points inside the switch are probably burned and the switch needs to be replaced. Troubleshooting is never an easy process, and the cramped area behind the instrument panel just makes the job more difficult, but it is necessary to check all wires, connectors,fuses, lamp sockets, and grounds. Good luck. j3h.
YOU HAVE A BLOWN TAILLIGHT FUSE OR PANEL LIGHT FUSE. THEY ARE NORMALY ON THE SAME CIRCUIT. Yoou could also have a bad headlight switch.
cause it would probalby be cool
brake light switch would be most common cause
What would cause your fuse to blow when you turn on your lights on your 1993 mazda 323 the fuse to the tail lights on dash lights blow?
leaving your lights on for a long period of time.. headlights or just playing the radio and leaving it play for a long time
short circuit somewhere, usually if you have towing lights plug at the rear end next to where the towball would bolt on they get crossed very easily
Check the switch on the brake pedal
There is no oxygen on the planet of Saturn. IF and WHEN you ever actually got to Saturn, not only would you freeze from the ice cold temperatures, but the gases (hydrogen and helium) would choke you to death. :(
If all are out then its either the fuse (under the hood) or the switch (on the pedal assembly). If its just 1 side check the bulb.
i there a switch on a saturn that would cause it not to start Yes the neutral safety switch.
Blown fuse? Damaged buss board?
I would first check all fuses. My 2002 uses a weird configuration and requires several fuses to work all of the lights properly.
water in the wiring or a low battery
Bad bulbs? Blown fuse? Bad switch?
On a 1999 GEO Tracker, a bad fuse can cause the headlights and dash lights to blink. A bad voltage regulator or alternator can also cause lights to blink and flicker.
probably the fuse is blown.
There are several things that can cause your GMC Envoy dim lights not to work. The most common cause is a blown fuse. A loose or corroded ground wire can also cause a problem.
Possible worn out brakes
Possible ground issue at the taillights.
