The fuse is there to protect the wire in the circuit from overheating and causing a fire. If the fuse blows, it is because the circuit is drawing more current than the wire can handle. Replacing the 15-amp fuse with a 20-amp fuse will allow more current to flow through the circuit, which could cause the wire to overheat and start a fire.
If your 15-amp fuse keeps blowing, there is likely a problem with your car's wiring or electrical system. You should take your car to a mechanic to have it diagnosed.
Here are some additional tips for replacing a fuse:
- Always use a fuse of the same amperage as the original fuse.
- If you don't know what amperage fuse to use, consult your owner's manual or a qualified auto mechanic.
- Make sure that the fuse you are using is the correct size and shape for your car's fuse panel.
- If you have any questions about replacing a fuse, consult with a qualified auto mechanic.
