W140 not blowing any air from climate control?

[Hatterasguy]

I am posting this info for a friend, so the info I have is second hand. Car is a 97 S320, I will look at it tomarrow. Sounds like all of a sudden the blower stopped working. No air from the vents regardless of what you do to the climate control.

Now if this was a W126 I could figure it out in my sleep, but its not.

But lets start with the simple stuff: So what fuse's are for the blower motor? Were is the blower motor and how do you get at it?
