BMW Repair: 1988 BMW735, bmw forums, power windows

Question
What would cause the Power locks, power seats & power windows to all quit operating? Everything else seems to be ok. Is there a relay or something they all operate off of? A fuse? Where is it?
Thanks in advance

Answer
I'm not sure where it is but i believe all those items are on the same circuit.  check a manual or some message boards for more specifics such as:

you can also search the archives for past problems, roadfly has been around for a long time.
