my cruise button is lit up at night but my defrost, mirror, sunroof, dimmer switch are all dark. are they supposed to illuminate? is it possible to replace a bulb or led inside the switches or do i have to replace them?

 

You didn't say which model year but on my 1991 they aren't made to light up.

 

its a 94. why is the cruise button illuminated then? the dimmer and sunroof aren't. and on the other side of the steering wheel the defrost doesn't illuminate. if it really doesn't light up im going to wire up a cold cathode inside the dash so it lights up or something
