screeching noise from front driver side wheel, loss of power steering, and A/C on 1997 Buick LeSabre

1. The screeching/grinding noise in the wheels has been going on for about 4 weeks, sounds like worn brakes, but the noise occurs any time the car is moving, unless I turn the steering wheel left. 2. On the drive to work this morning, the power steering failed and at the same time, the A/C stopped blowing cold. Could they be related? This car is otherwise in great shape, it's paid off, low miles and great fuel econ. Please let me know what you think is wrong. Want to have some ideas before seeing the mechanic. Thanks!

You may have 2 different problems. You may need brakes ( can't believe you have been driving for 4 weeks like that) and it sounds like the serpentine belt broke hence the loss of PS and A/C. Get it checked immediately.

I just got off the phone with my mechanic buddy. It seems like the tensioner pulley is broken and due to the lack of tension, the belt fell off. I'm going to replace the pulley and the belt and report back on the results. Thanks for the diagnosis.
