Hi Chris....welcome to the Forum
I would advise taking the car to an auto electrician, as it's a 20 amp fuse which suggests that there is a short circuit to earth, which if the fuse did not blow then an electrical fire could ensue, which is definitely not a good outcome. For what it cost, and it may be quite quick that the sparky finds the fault, but without the knowledge and equipment to trace the fault it is a non-event in my mind.
Let us know what you find
Cheers, Trevor
