Answer 1 - Fuses That "Blow" Repeatedly
Without being able to "hands on" troubleshoot the circuit served by the repeatedly blowing fuse, none of us can identify the specific defect which is causing your problem.
Therefore, the following generic answer can be applied to any electrical circuit, whether in a vehicle, or in a building, whether direct current [DC], or alternating current [AC].
Fuses [and Circuit Breakers] are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] and other components from short circuit conditions and/or overload conditions which cause an extremely large flow of electrical current [measured in Amperes], which causes overheating of the conductors that results in damage to the insulation and the conductors.
And in a worst case scenario, the probability of a FIRE which could destroy the vehicle, house, or other structure in which the circuit is located.
When a fuse or Circuit Breaker [and replacement fuses, or repeatedly "tripping" Circuit Breakers] "blow," especially if it happens repeatedly, is an indication of an UNSAFE CONDITION in that circuit, usually a short.
The fuse or circuit breaker is doing what it was designed, intended, and installed to do; that is to protect the conductors and components of the circuit which it serves.
The proper "fix" for this issue is for a qualified technician, who knows what he or 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 people will suggest installing a larger fuse or breaker to solve the problem, BUT that will only increase the hazard, not correct it.
Do not follow "bad" advice by installing a larger fuse in a misguided attempt to correct the problem. To install an oversized fuse would almost guarantee damage to the wiring and the probability of an electrical system fire.
brake lgiht fuse blows when shifting gears?
Check the fuse
you need to get a bigger fuse
There is a short in the wiring or a corroded brake light receptacle.
I am currently having the same problem you are having check the fuse to see if it is blown the blinkers and brake lights are on the same fuse my system has a short in it somewhere and is popping the fuses I am in the process of running new wires since the wonderful people at Chevy ran all the wires thru the frame and you can't access them
Check the 30 amp brake fuse (green) in the engine compartment fuse block.
Bulbs? Sockets? Steering column switch?
No brake light.fuse blows
It sounds as if you have an electrical problem that needs to be checked. You may even have the wrong fuse for your brake lights.
One fuse controls the function of the hazard, reverse, and turn signals of the car. When there fuse blows all the components stop working.
IT COLUD BE A RELAY BOX multi function switch( turn signal, lites ect.)
First thing I would do is check for aftermarket trailer wiring. There's a short somewhere. most common at the rear around the taillights, sockets, wrong bulbs installed. etc...
