Leaking Jeep and crazy windshield wipers

I own a 2000 Jeep wrangler Sahara with around 62k miles. I have noticed that when it rains heavily for a few days, I start to get a slow drip on my shoes from under the steering wheel area, just the left foot though. Recently, during our bad rain storms the windshield wipers have blown their fuse while driving and on another occasion went from an intermediate wiping motion to the highest setting on its own, and wouldn’t stop even when I turned the wipers off. The only way it stopped was when the fuse finally blew. Please help me. I’ll bake you brownies…
