Would appreciate some help here, guys. The backlight for my temperature-setting wheel on an 1986 300SDL is out. I took the whole temp section out of the dash enough to see that there aren't any fiber-optics going into the wheel housing. There are optics for the other switches though. There is a big connector with about 15-20 wires that connects behind the temp wheel, though not directly into the wheel housing itself. Anyone know if the light is fixable and how? Thanks.
