Fuses and Circuit Breakers are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] from short circuits and overload conditions which can cause extreme overheating that can result in damage to the insulation and the conductors, and worse, the possibility of a FIRE which could destroy the vehicle.
When a fuse, and replacement fuses blow, especially if it happens repeatedly, is an indicator of an UNSAFE CONDITION in that circuit, usually a short. Do not 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.
The proper "fix" is for a qualified technician, who knows what he/she is doing, to troubleshoot the circuit, find and identify the defect, and make proper repair [s], BEFORE replacing the fuse again [with the properly sized fuse].
