I was going to add the same advice to my previous post, but forgot. 
So, I'll "second the motion" --i.e.,  Ed's spray cleaner advice is 
worth a try--and it's quite easy to do. I did try that a couple of 
times when my A/C blower had the squealing problem, but the 
improvement was too short-lived to persevere with that approach. 
Hopefully YMMV.
