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 which is causing your problem.
It appears that you have not yet found the cause which is probably a "short circuit" condition in the wiring between the brake light switch and the tail light assemblies.
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] 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 "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, protect the conductors and components of the circuit which it serves.
The proper "fix" 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 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 over-sized fuse would almost guarantee damage to the wiring and an electrical system fire.
Probably a short in the switch needs to be changed.
Problem solved...the culprit was bare neutral switch wires shorting out and blowing the fuse!!!!!
I suspect the switch is bad.
to keep your car from blowing up
Check switch
for fuse to keep blowing, there is a short in the eletrical system somewhere. check the a/c switch and the a/c clutch
There is an electrical short to ground in the fan switch or in the blower motor itself.
Look for corrosion If you have a trailer plug or brake controler katcarving here to add info on this . we had same problem changed out brake light switch under brake pedall 12. oo buck and fuse stops blowing
You may have a short in the switch or in the wire... Check wires that go from the switch to the hardness for any pinch or rubbing in metal. Also, When checking the switch pay attention to with one is blowing the fuse. This way you will know which one is bad. If you find out it's a wire or switch on any other door other than the driver's door. You can disconnect that switch until you get it looked at by a professional.
Fuse, switch, speed resistor or motor.

No, you do not.
