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.
If it blows when trying to crank, the starter has failed.
You have a ground wire that isn't grounded causing a shortage therefore blowing the fuse....I would start with the ground wire that is connected directly to the starter itself
I believe the starter solenoid is on the same circuit. A failed starter is most likely the problem.
You have a short circuit/over current problem with the circuit. If the wires are not touching metal, then the starter may have failed.
could the pcm fuse be blowing because of a short in the air conditioning switch I have seen the starter be the cause of a blown pcm fuse.
Check the wiring on the starter. Also check all grounds
the starter has failed.
i have a 96 dodge avenger 2.5 and it keeps blowing my ignition switch. any idea why?
I have a 2003 iron horse and had starter rebuilt , I'm wondering is there suppose to be a shim , it keeps blowing out my clutch
Disconnect the electrical connection at the blower fan motor, put a new fuse back in and see if the truck starts and runs without blowing the fuse. If so replace the blower fan motor. If the fuse still blows, disconnect the ac clutch wire from the ac compressor and try again.
Failed pump, or wiring shorted to ground.
Faulty tail lights - causing a short.
