Electrical problem
2001 BMW X5 6 cyl All Wheel Drive Automatic 92000 miles

The aircondtioner blower comes on when the car is turned off. The battery went dead and I replaced it but after 5 days it went down again. Itested the alternator with the car running and got 14.3 volts. I do not think it is the alternator causing the battery to die but the airconditioner blower coming on when car is turned off.

Check for a key off draw and consider replacement of the final stage for the blower. 64-11-8-385-549 is the part number.
