On the third gen defroster switchs, (at least on the one I am looking at now) there are two L.E.D.'s wired into a circuit board inside the switch.
Pay attention to polarity when replacing, and check the bias resistor(s) first.
Trix - Thatnks for the info. I'm a little surprised that the F-cars had the LEDs and the '94 B-cars had an incandescent lamp, though. Go figure. More tidbits of data to file away (and probably lose).
