I can't answer your question, but usually dashlights and taillights are on the same fuse [circuit], and NOT with the head lights. Answer 1 is correct as, normally, the headlights are on a "dedicated" circuit, with NO other lights or devices sharing. I suspect this is a designed in safety feature due to the potentially critical function of the headlights. Therefore, the fact that the "dash lights" continue to "work" is immaterial to the problem with the headlight. Now, to the more important OTHER part of your question. NOTE that ANY TIME you have a FUSE WHICH CONTINUALLY "BLOWS" upon replacement, INDICATES SOMETHING IS VERY WRONG !!! A fuse is SUPPOSED to blow out anytime there is an OVERLOAD or a SHORT within the circuit which it PROTECTS. See a related question and answer, "What are the origins of the fuse?" This related question and answer contains a comprehensive discussion of what your repeatedly blowing fuse means. The bottom line of your problem is that there is definitely something SERIOUSLY wrong with your headlight circuit, and if not properly analyzed and corrected, could resuslt in a serious nighttime accident, OR serious damage to your vehicle's wiring system, or worst case, a fire. Please read the referenced question and answer, and if you are not capable of finding and correcting the fault in the headlight wiring circuit, then get a PROFESSIONAL AUTOMOTIVE ELECTRICAL TECHNICIAN to fix the problem before it results in serious consequences.
There are individuak fuses for each headlight
check all brake bulbs a filiment may have shorted out
Dead short either in wiring, sockets, or in steering column Remove bulbs and try turn signal switch if fuse still blows probable location in steering column
have you tried turning the ouside dial on headlight switch that dims the gages bright or dull had a similar problem with 98 corvette no dash lights or hvac or running lights turned out to be multi function switch (headlights turnsignals)
Check your tow bar and trailer brake light wiring. It may be grounded. I had this problem with my 92 roadmaster wagon. Tom.
could be bad wiring
The owners manual will still which fuse it is amperage and the location.
MAke sure that the sensor above the brake pedal is still in good shape,check fuses.
See answer 1 in "Why does my fuse keep blowing,?" and answer 2 in "Why would you keeep blowing headlight fuses but dash lights still work?" These answers discuss fuses, their purpose, how they work, and the reason(s) that they "blow." The short answer is that you have either an "overload" condition on the circuit in which replacement fuses continue to fail or, a "SHORT CIRCUIT." Your question indicates that you have not been able "to find" the cause, but if there is no "extra" electrical load which has been added [such as sound equipment, for example] to that circuit, then it is almost certain that there is a short circuit fault. The fix is to locate the fault, and correct it [as for example, to replace or reinsulate a wire in which the insulation has "chaffed off" on a grounded sharp, bare metal edge]. Good luck. j3h
Check the headlight fuses located in the main fuse box. On a 2002 Nissan Altima the main fuse box is found inside the engine compartment.
faulty brake light switch (on pedal)
Answer- just replaced headlight switch on 1993 merc.grd.marq. took care of no tailights, no dash lights.you have a bad ignition switchOR, the wiring behind the headlight switch assembly might be bad, the harness can have warped or cracked and/or the wires may have come loose or otherwise lost their connection. Inspecting the wiring for the headlight switch would be the first step if it only occurs when you want the headlights or parking lights on, and the headlamps work but not the gauge cluster lights nor the tail lights, BUT, the brake lights still work.
check fuses, check bulbs, from there see if there is a grond for your reverse lights that may need cleaning. If still no lights, make sure there is a good wire back to the transmission for your lights. Still no luck, look into the sensor on tranny for your reverse lights. Good luck.
only the headlights are suppose to flash on a headlight flasher
check the fuse for dash lights
changed brake light switch at pedal and still no brake lights
AnswerThe bulbs for the brake lights are usually separate from the normal tail light bulbs. Check and replace the brake bulbs first, and if they are still not working examine the fuses, switch and wiring.
Turn the headlights on the whole way, then push the headlight knob back in, leaving the parking lights still lit. This will hold the headlights up, without having them turned on.
I had the same problem. It's the headlight switch. It needs to be replaced. You have to remove the dash for that, which is easy. The switch rins from $107.00 on the internet, to about $140.00 at the Chevy dealer.
Did you check the switch on the brake pedal assembly?
on my 93 civic, there are 5 separate fuses for headlights. left low beam, right low beam, left high beam, right high beam, and daytime runner
The whole headlight on these 03 silverado is not that hard to take it out. When you pop the hood open as you look on the headlight there should a long piece of tube metal that is holding the headlight onto your car. As I recall there shouldn't be any screws or bolts holding the headlights. That is for headlights, not "Daytime Running Lights". Still looking for answer!
Check the wires that plug into the light sounds like a bad groung or no power goining to the headlight. If that's not the problem check the dimmer switch.
