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
Check switch
Yes.
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
Check your tow bar and trailer brake light wiring. It may be grounded. I had this problem with my 92 roadmaster wagon. Tom.
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)
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
The owners manual will still which fuse it is amperage and the location.
could be bad wiring
MAke sure that the sensor above the brake pedal is still in good shape,check fuses.
check the fuse for dash lights
