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.
