Depending on the type of squeal...it could be. It could also be a vacum element gone bad as well. Hopefully it's the blower, cause if it's one of your elements....you have to take apart the dash to get to them.

annoying
I have the same issue, used to also have it with my old '91 190E, but I keep thinking it may just be leaves and debris that have built up under the plastic vent housing the windshield wiper blade. I will try to clean mine out tonight after work and see if it helps at all. But I'm sure there is plenty of pine needles and leaves in there causing clogging.
