AC Squeak & low growl
2014 X1 with ~123k miles. At low speeds I notice a low growl from the AC, I believe its the AC because when I turn it off the growling goes away. Additionally there is a squeak when the fan speed is low, the squeak is still present when the fan speed is increased but not as noticeable. I recently had to change out a wastegate actuator and looked inside the blower cage and saw no debris present. Any thoughts as to what may be causing these issues?
