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.

2001f150 5.4 the dash light fuse 5amp keeps blowing you cant find any reason for this How can you locate the true problem or what would be the most rationale issue casuing this?

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

How do you fix the tail lights and dash lights if all other lights are working on a 1992 Mercury Grand Marquis?

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.


Reverse light will not work on 1990 Geo Metro?

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.

Your brake lights work when you brake not when you turn lights on?

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.


Do I need to replace the entire instrument cluster on 2001 Monte Carlo SS if gauges still work but the lights do not and all the fuses check okay.?

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.

How do you change the bulb on the Daytime Running Lights on a 2003 Chevy Silverado?

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!


You just installed a new headlight in your Nissan 300ZX and also checked the fuses but it still will not work What could be the problem?

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.
