Anyone know what type or bulbs are in the Defrost and Fog switches?

I need to replace mine.

Also, do the cap just pop off?

Don't know the bulb size. My bulbs were just loose not burned out. Pushing them into the socket fixed my problem.

The Old design is like a drinking cup upside down placed into the pull ****--bottom of the cup has the insignia. When you push back the rubber lip and tried to pull out the fog light or defroster plastic insignia You may break the "cup" .

The new design is a disc which is easy to remove and replace into the pull ****. I have an extra fog light disk if you want it.

I have an 89, so I think mine might be the old design. I'll have to run out and see if I can pop the cap off. I may need that disc after this haha!
