Problem with backlight

[Ivan141]

Weird that your air control is also not lighted. I've had both problems once but they weren't related. the wiring to the lighting switch tends to get a bit loose on ae86's.. I used to give the light switch a tap and the dashlights would come on again. My air control lighting once failed too, but that was because I shortcircuited it by accident. Somehow that problem fixed itself after a while.

My best bet would be that you should check your connectors and jiggle the wires a bit to see if that helps. If it does you know where to do some soldering/cleaning.
