Yes. When I had only one bulb working it only illuminated the dial. If yours is similiar to mine, I pried the woodgrain facia off from around the controls and this allowed me access to the 4 phillips head screws holding a black plastic plate holding the control unit. Note that there are more than 4 screws, 4 hold the plate others hold the control unit to this plate. With carefull prying and wiggling the plate and control unit came out and on the back of the plate are the 4 bulbs across the top of the buttons. I suspect you can order the bulbs through FastLane. Good luck.
