Thanks, Bruce B.

Just to close this thread... I bit the bullet and had the dealer (Keeler, Albany NY) do the work. They replaced the blower motor (part A 000 830 82 08 – $313) and they also replaced the Blower Regulator Switch (part A 124 820 27 10 – $288). The labor ($89/hr) came to around $400.

All I can say is OUCH.

Thanks to all who replied. If I had more patience and time, I would have gone at this myself.... or at least bought the parts online and brought them to the dealer.
