Thank you!
You should probably start your own thread about this topic.

A blower screeching noise is likely a bad bearing or an obstruction.

The blower motor assemblies on those cars are a bit different than the others. You should do a search on them and see what other members on here have to say. I've never worked on one so I can't directly comment.

Here is a link to the factory service manual for your car:
Model 107
