Blower motor continues to run even with the ignition off, and key fully removed. (it's really freaky).

Found parts online $60, readily available. (My local dealer, BMW Concord, CA. quoted me $193 for the part), found video on YouTube how to replace, took about 20 minutes.
Continuing running of the blower after car is turned off. Only 2 speeds of blower; on or off. Cold or hot.
