Does  anyone know if you can replace the light in the rear defrost
switch?   If so how do you get to it without destroying the  switch?

yes u can replace it..  but be careful taking your dash cluster out  this
time of year ...those things are fragile enough as it is, and with the  cold
temps 25 yr old plastic likes to shatter in a million pieces...i would run
the van for a while and let the interior temps get to at least 75 degrees
(including interior surfaces)

the warmer the plastic is, the more flexible it is.   the colder  it is,
the more likely it will crack.

ive even used a hairdryer to heat plastic in the immediate area i am
working on..
