First step would be to verify the source. When my blower motor started to squeal, I first suspected (hoped?) it was the little temp sensor fan. It wasn't. The cold air when running A/C seemed to trigger it at first, but it progressively got worse. Maybe pop the hood and put your ear near the cowel?
