What year. They changed the design. either or, the fan switch and temp switch have little lamps(bulbs). You have to take the center consul apart to get to them. unless you remove your radio and KNOW where to put your hand and what to pull, LOL. Now, the older style used one LED on each of the 3 vent controls. Newer style used fiberoptic lines from the little lamps I talked about above. Just take it apart, its all easy. the little lamps have 2 wires going to them. They mount in a little plastic socket that the wires plug onto. When you have it apart and don't know whatto pull, just turn the lights on, and you will see things clearly. good luck
