Electrical Problems with E28

[Harrisonn <hnng@xxxxxxxxxxxxxxxxxxxx>]

Hi BMW aficianados

I recently purchased a 1982 528e and experienced the following problems
today:

1) Electrical door looks failed.
2) Radio and LCD clock stopped working.
2) Soon after the power windows stopped working.
3) Brake light warning came on (and brake light doesn't come on now).

I checked all the fuses, but none of them are blown.  What should I check
next?  Any suggestions for solutions are welcome.

Thanks,
harrison
