What you have is a burnt out multi-function switch. It's happened to lots of PT owners. Our resident expert (MX-5) has identified the problem as a very small part in the switch that doesn't hold up to the heat that's generated when the fog lights are on. Some seem to last a long time, while others only make it a couple of years. There's no fix as of right now. You have to replace the whole stalk. They run somewhere around $60 (I think) and if you have any capability of handling a few tools, you can do it your self. A few screws on the steering column and on the stalk itself. Two wiring harnesses have to come off and the new switch installed in it's place.
Oh yea,
WELCOME to the forum.
