Come on guys, these are some of the worst recomendations to solve this I have ever heard of. You NEVER replace a blowing fuse with a larger fuse! That will only make the problem worse, if not catch the car on fire.

You need a wiring diagram first off. You'll get no where without it. From that you can figure out what exactly runs off that circuit. Disconnect things from that circuit one by one. Use the multimeter to see if the circuit is still grounded after you disconnect the latest part. There maybe connectors on the circuit also. Unplugging those will take out more branches of the circuit quicker and will speed up the exact item or location giving you trouble.

Do not put your multimeter across the two terminals of where the fuse goes. Thats why you blew out your meter. Just check the non powered side of the fuse to ground. If its grounded move on to the next item.
