[V8] Air blower stays-on

[Peter A. Green]

Wondered if any-one had BTHT (been there - had that) of the air conditioner blower motor staying-on after pressing off on the control head.  The air conditioner operates normaly except for the blower remaining on.  I suspect a relay but my Audi 'stuff' is in storage after a recent move and the thought of routing through boxes of stuff is overwhelming.  Any suggestions?
