Need Help w/ Electric Problem
 

I have a 1988 300E. The rear windows and cigeratte lighter don't work. Checked all fuses, all appear to be okay.
Also, can anybody tell me whether all 300E's came with Cruise Control? I have the Cruise Control lever but it doesn't work either. Also, does the gear shift indicator (automatic) panel supposed to light up at night? That doesn't work either. I think it may all be related. What do you guys think?
