Disconnected the electric adjustment for both the front seats still battery drained.

Current draw test will show up a problem, hook an Amp meter between battery Pos and battery cable, key off doors closed, read amps if high, pull fuses on at a time to see which circuit is pulling current, there will be a normal draw around.1-.2 amps for system memory.
