Humming noise when a/c on
I have about 700 miles on my LTZ and have noticed a humming noise when the air conditioner is on. Never heard this noise on other trucks I’ve had. Almost sounds like how a power steering pump low on fluid would sound. Anyone have same experience ?

Does the sound come on when the fan is off? Have you tried to find out where the humming noise is coming from exactly? Does it occur when you have the heater on? Is it only when the A/C is on?
