Broken Electric Seat

So I just recently bought a 1990 735i. The driver's seat does not work. When any of the buttons are pressed it does do anything. It dosen't even make sounds. What do I do?

First check fuses. If they are okay, check under the seat to see if connector is loose or unplugged. if all that is okay, use a meter to see if you have 12volts to the connnector. If not backtrack to see where you lost voltage. If voltage is there, it is a good chance the switch is bad. I have had to replace the switch in two of my three. Friends tell me they two found switch failure common on driver's seat. I wish you luck

have 1998 740il found switch housing broke removed and used soldering iron to put back together switch was good hope that helps

forget to mention if is this problem steering wheel memory will not work either
