I think the main e30 radio fuse is 12.  The optional amp is 27, power antenna is 28.  At least that's what is says in post 4 here.

Check the power window switch for corrosion.  They're a bit of trouble to get apart but it's a common problem.  Hopefully it isn't the motor itself.  The switch terminals corrode & don't pass enough power to turn on the window motor.  I usually sand mine with a bit of fine paper & lube them with di-electric grease.
