Hey guys.
I've seen a thread about upgrading the dash lights and switches to LED bulbs elsewhere here on MUD. I'm not going that route just yet, but I have a issue regarding the mirror switch. The thread I saw showed the mirror switch was lit. I've gone around and changed 5-6 burned out bulbs in my dash, and in the process noticed that the bulb was actually missing in my mirror switch although there was an open hole to install it. The parts catalog (I work for the dealer) doesn't even list a bulb in that location at all. Okay whatever, I figured out the bulb that fit the switch and installed it today. The problem is that although I can see the light coming on from the back side of the switch, there is no illumination on the front side. Does anybody have any thoughts on this? I haven't checked yet to see if there are various mirror switch part #'s for different year 100 series, but it seems strange that the housing will accept a bulb that won't illuminate the front of the thing. I just don't get it.
