The dome light in my '83 300SD doesn't work. The switch wheel doesn't make contact anymore. I was looking on parts.mbz.org for a replacement, but there are two:
a) interior light switch

There's a ~$40 difference, and I'm not sure which to get. Any help?
Also, the light on the instrument panel that looks like a coil and tells you when the glow plugs have finished warming up the engine so you can turn the key over, that light doesn't work on my car anymore. On my '84 300SD there was that light, and also a buzzing sound, but on the '83 there was never any sound, just the light. So now I kinda have to guess when to turn the engine over. It's not a big deal, just kind of a nuissance, and I was wondering if anyone had any ideas. I replaced the fuse for the instrument panel, and the other lights (brake, etc) work fine.
