Fuses That "Blow" Repeatedly
Without being able to "hands-on" troubleshoot the circuit served by the repeatedly blowing fuse, no one can identify the specific cause/defect.
The following generic answer applies to any electrical circuit, whether in a vehicle or in a building, or whether alternating current [AC] or direct current [DC].
Fuses [and Circuit Breakers] are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] from short circuit conditions and/or overload conditions which can cause extreme overheating of the conductors that can result in damage to the insulation and the conductors. And in worst case, the probability of a FIRE which could destroy the vehicle, house, or other structure in which the circuit is located.
When a fuse [and replacement fuses, or "tripping" Circuit Breakers] "blow," especially if it happens repeatedly, is an indication of an UNSAFE CONDITION in that circuit, usually a short.
The proper "fix" is for a qualified technician, who knows what he/she is doing, to troubleshoot the involved circuit, find and identify the defect, and make proper repair [s], BEFORE replacing the fuse again [with the properly sized fuse or before resetting a circuit breaker].
Some ignorant few will suggest installing a larger fuse or breaker to solve the problem, BUT that will only amplify the problem, not solve it. Do not follow "bad" advice and install a larger fuse in a misguided attempt to correct the problem. To install a larger fuse would almost guarantee damage to the wiring and an electrical system fire.

Why would tailights and dash light not work on 1997 Ford Taurus?
Blown fuse.
What would cause the instrument panel fuse to blow 1989 cadillac deville?
short in dash light circuit, but also check tailights. Sometimes no dash lights, AND NO TAILGHTS.
Why would the tailights stop working on a 1993 Aerostar bulbs are good?
Check the fuses
1999TahoeZ71 keep blowing fuse everytime I turn on the head lights instumentcluster lights don't work nor do any of my rear night time lights work have already replaced light switch?
I would unhook headlights, then tailights, and so on till you find the circuit.You may find a shorted bulb or circuit. I had this happen in my shop and it turned out to be an courtesy light bulb that had a dead short across the base but appeared fine. Good luck.
What would make dash light fuse keep blowing on 89 Chevy cacaleir?
A short in the wiring.
2002 volkswagen beetle left tail and brake lights work fine on the right the tail light works but goes out when brake pedal is pushed and brake light does not come on only happens with headlights on?
This sounds like an issue that VW has recognized and is fixing for free. I would recommend calling your local dealer and consulting them on whether this is a problem that they have sent out a recall about.
Why would turn signals work but tail lights do not?
Check bulbs they are double filamneted smaller for stop lights larger for tailights Check fuse (parking/tailights/dash) Maybe a bad headlight switch
What would cause the dash light fuse blows in 96 cavalier?
you probally have a bad wire that is shorting out and blowing your fuses.
What would cause the tail light fuse to keep blowing on a 1991 Isuzu trooper?
Short in the wiring or one of the bulb receptacles.
Is there an easy fix to your car blowing out light blue smoke in the morning?
That would probably be bad valve seals. It would depend on the vehicle as to how easy or hard it would be to repair.
What would cause your tail lights and dash light fuse to keep blowing on a 1991 mercury tracer?
you could have a short between the two.
What should you do if the brake lights keep going out on your 1992 Chevy Cavalier?
Are you blowing fuses or are the bulbs blowing? Blowing fuses would be a sign of any wires or metal contacts in your brake circuit grounding out or shorting on themselves. You'll have to check all of the wiring in your brake light/switch circuit to be sure.
