2007 Ford Focus SES ZX5 fuse problem?

[SolitarySiren]

Today, I discovered a fuse had blown in my focus. It was the fuse linked to the dash lights. I replaced the fuse with one of the proper amp requirement and thought I was fine. While I was driving, my dash started to smoke, I pulled over, turned off the engine and let the panic roll out of my system. I tried to turn on my car, but nothing worked. I took out the fuse in question.

I noticed my dash lights were still on, when the actual switch to the lights was in the off position. I switched it to the on position, and the lights turned off. I tried to start my engine, and it worked.

I turned off my car, and took out the key, only the engine was still running. I turned the light switch to the on position and that turned the engine off.

Does anyone have any idea what's going on?

Thank you

It's an old question but you probably have some wires that shorted together when the insulation melted off of them. The smoke was from the melting insulation.
