If it isn't one thing on a W124, it's another

Having only just replaced the 3-way heater hose on my 1993 300E2.8, the blower has now stopped turning.

The fuse is good, multimeter tested, and replaced (just in case my meter was lieing to me), and the blower motor itself is fairly new (less than 12 months old).

The multimeter also reported no voltage over the fuse terminals when I had the ACC unit on 'defrost'. Could this mean I have a dead blower motor regulator? Is there any easy way to tell without removing the blower motor from the car?
