Why is there a whistling noise when ac, heat or defrost fan is turned past 3? This happens when car is in park or in motion.
What is your question?
Just purchased a used Certified 2017 Ford Escape SE AWD with 27000 miles. The fan makes a high pitch whistling sound when fan is past 3 speed. This happens when in defrost, ac or heat is turned on, whether the car is in motion or in park. Purchased the car with the understanding that Ford Dealer would fix the whistle. Picked up the car after 3 days and was told the technician could not hear it. Turned the car on in the parking lot with the sales rep and we could both still hear the sound. Sales rep brought the technician out and I showed him when it whistles. The car is still at the Ford dealer. I don't think they have a clue or they don't want to fix the issue.
What makes this problem better or worse?
Low fan speed
How long has your 2017 Ford Escape had this problem?
RepairPal Certified shops can diagnose and repair your 2017 Ford Escape. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
This could be few things like a bad blower motor or debris somewhere in the ducts. If it's at the dealer and they verified the concern it will be fixed. You may have to be patient with it but seeing as how the car is under warranty they have to fix it.

Did they ever find out what the problem was? My 2108 Escape does the same thing.
