A/C fan works, but frequently makes a squealing sound as if the fan is hitting something. What is wrong, and how much to fix?

Answers from the Automotive Experts

Amanda J. Pierce, MBA Bett, Thank You for writing into AskPatty!! To address your concern, a "squealing" noise may be coming from one of your drive belts. This may be an A/C belt or power steering belt. I would have your belt inspected for wear and cracks, many times it may just require a bit of "belt dressing" to condition the belt and quite the sound. That would be a low cost solution, IF that was the only problem. Hope This Helps!! A. J. Valle

Diane Larson, Owner/Manager at Larson's Service Hi Bett:) The squealing noise may be coming from your blower motor, which is located on the passenger side, dash. The shaft & bearing inside the motor may be dry and intermittently causing the noise. At my shop we would replace the blower motor, however I found a link that explains about it and how you could attempt to lube it, may or may not work..... http://redhouseon7th.com/redhouse/howto/1999BuickBlowerReplacment/bearing1.html motor housing To find out how much replacement of the blower motor would be - check the Repair Price Estimator on my website www.larsonsservice.com - Hope this helps:) Have a Fun Day!
