Temp Control Lights
I have a manual one on my '98. There's one way to find out. Remove the bezel surrounding the radio and temp control (it pops out with a flat-tip screwdriver). The temp panel is attached by 4 bolts that will be easily visible. On the older model, there are two t-10 bulb carriers, and twist off to access the bulbs. Your may have these, and are easy to replace. If you do NOT see these bulb carriers, then that panel will have to be disconnected, and taken apart, just to see what has burned out (soldered bulbs, cold solder joint on the indicator panel, etc). Lets hope it's of the easy variety.
