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. However, the cause will be found to be a "short circuit," or "overload" condition in the circuit for which the fuse continues to "blow."
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 can cause extreme flow of electrical current [measured in Amperes], and overheating of the conductors that can result in damage to the insulation and the conductors. And in a 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 fuse or circuit breaker is doing what it was designed, intended, and installed to do, protect the 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 and install 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.
fuse relay wiring switch
Check fuse for parking lights--should be same circuit could be burnt out bulbs could be bad switch could be dimmer rheostat
If carb. Could be a bad fuel pump
The lights on your Buick could be out for a number of reasons. It could be blown fuses, faulty wiring, or dead bulbs. Your mechanic would be able to test this.
I own a ford f150 and my tail lights are not working, but my brake work. What could wire or what could be causing that.
You could have a blown fuse, these lights may also have a knob to dim them make sure this is on.
Check fuse for parking/tailights Could be a bad headlight switch Could be an open in the dimmer rheostat
Could be the air bag system has a problem. Are there any lights on?
Check bulbs Check fuse for parking/tailights Could be a bad switch
there could be a bad ground for the lights, or there is a short somewhere between your fuse panel and your light
Could be anything from a bad flasher, bulbs are out or the turn signal bulbs could have dirty contacts.
Could be a blown fuse bad bulbs or bad switch check you wiring in the lights to make sure not getting a short
