Help, elec prob on road trip.

[Sopicki]

Hi all,

I'm on a road trip with my family right now and I've got a bit of an electrical glitch. Our car is a 1987 300e.

Symptoms are:

Dim passenger side headlamp (High beam selection causes lamp to extinguish completely)
Turn signals don't work (emergency flashers do though)
When turn signal is selected (either direction), outside air temperature display goes blank
Faint crackling sound from behind instrument cluster when turn signal is selected

I've got to make a 3 hour trek home tomorrow. I suspect a bad ground but I don't really have any resources with me.

Anyone have any suggestions?

Thanks in advance,
