The illumination on my climate control is not workin on my 92rwd...not the digital display but the words and writing over the buttons.....the mirror controll light isnt working either..wat cud be the prob?

Take off your dash center bezel (the one that goes around the climate control, mirror, and stereo). Loosen screws on the mirror control and on the climate control. Pull out the climate control first. The cover can be popped off, revealing (I believe) four light bulbs. Replace as necessary, put back together, and it will illuminate again.

For the right-hand mirror control, take the light bulb out from behind the face panel. Replace.

Now put everything back in place, re-attach the bezel, and it is fixed.
