Anybody else experienced this? I doesn’t seem like an issue to me. If I had to guess why we hear it, it’s because it’s a 4 cylinder in a relatively good size vehicle vs a V6 and it’s powering a compressor and other things at the same time.We just purchased a 2020 Explorer with 33k miles recently from our local Ford dealer. Wifey just noticed the other day when the AC is on it kind of makes a lite whine that changes pitch with the engine speed. It’s only noticeable when the fan speed’s low. When it’s cranked up it’s not audible. Does this sound like an issue?
