Changing Rear Window Defogger Button Light Bulbs (Post 20 of 27)

The are 2 tiny lights in the rear window defogger button.
1 comes on when you turn the regular lights on.
1 comes on when you actually turn the defogger on by pushing the button up.

If either or both of the lights burn out, simply replace the entire switch.
