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.

The starter and fuel pump fuse blows in our 2001 chrysler sebring a lot almost every time it rains what could be the problem?

What will cause the fuse to blow on the starter solenoid of a 220 Bayou kawaski 4 wheeler every time the battery is connected?
The reason the fuse blows every time is because either you don't have the right fuse or you don't have the right sized wire to connect the two together.

This is the starter fuse I am talking about. It doesn't blow every time. It might go weeks before it blows again.
What could be the problem if the horn fuse on a Mercedes 190 blows every time it is replaced?
It seems that you have a short-circuit on your horn circuit. Check to see if the terminals of your horn are touching any part of the cars body. Also see if you can disconnect the horns, change the fuse again, if the fuse holds then replace the horn(s)
On your 1985 Toyota pickup the fuse blows out when you turn on the lights the head lights stay on but not the rear lights?

What is the ctsy fuse on a '96 gmc jimmy and what does it do also what should you do if you replace the fuse and as soon as you put a new one in it shorts out?
