Dash lights quit, gauges and idiot lights work. Help

When I pull the headlight switch out on my 91 ford f250 my park lights goes out and keeps blowing a fuse

It's most likely a burnt fuse. Check the fusebox in the cab first. If none of those match the dash, check the underhood fusebox next. A burnt fuse looks like a burnt light bulb. As long as the metal part in the middle is connected it should still be fine.
