I searched the forums but didn’t see anything that fit my exact problem, so hopefully someone can help. I have an ’08 250 that makes an odd humming noise from the A/C. If I have the A/C on and bump the temperature up or down a degree or two, I hear this humming noise for a second or two and then a noise that sounds like small gears turning for another second or two. Occasionally I hear the noise even if I’m not messing with the A/C. It seems like it’s more constant than it used to be.

I tried to record the noise on my phone but the microphone won’t pick it up. But it’s loud enough that I can hear it even if the radio is on since it sounds like it is right behind the center vents. From what I have read it might be the servo?
