Short or too much load.
Answer 2Answer 1 is correct, but here is some more information to help you understand the issue and the hazards that could be involved.
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, house, or other structure in which the circuit is located.
When a fuse [and replacement fuses or Circuit Breakers] "blow," especially if it happens repeatedly, is an indication of an UNSAFE CONDITION in that circuit, usually a short circuit issue.
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 or circuit breaker].
Some ignorant few will suggest installing a larger fuse or breaker to solve the problem, BUT that will only amplify the problem, not solve it. Do not follow "bad" advice and 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.

There is more than likely a short in the wiring somewhere.
If it had a short it would blow a fuse. You probably have a faulty flasher relay.

It could be that you need coolant or it's low.
If the blow was fatal you would never recover. If the blow was very light you would just say "ow" and you would be OK. In between the two - that depends on how hard the blow was.
Check the fuse?
