hi all, i'm looking at buying a 1993 530i Automatic.

Now the current owner is a "Poor uni student" by his terms and can't afford to fix it's electrical gremlins. the wipers only work flat out, same as the A/C, the remote central locking doesnt work and the windows wont go back up. I have read a little into this and apparently the Relay module is responsible for all this. I'm not familiar at all with the 5 Series so i'm running blind here.

Any help would be very much appreciated!!
