THe Problem: The driver's seat on a BMW 635SCI (M6) 1988 is broken. Would like to swtich the Left and Right power seats... the problem is he wiring harness are not interchangeable. ...IF you cut the wires and swithch do you lose more than the memory..The right seat is loose and leans backwards and it is twisted on the right side....Also does anyone know of a source of cheap parts by mail or in Toronto Canada ???? Thanx
