I have a 1979 Lincoln Continental Williamsburg Edition. It has 2 switches on the floor, left corner. The lower one is the dimmer switch but I don't know what the upper one is for. Any ideas? Thanks.
The switch I'm inquiring about isn't in the manual. I can't figure out what it goes to. This car was owned by my grandfather, one owner, and it's not been modified. This is a factory switch.
