When my A/C is switched on I hear a whining harmonizing kind of noise, it is in relation to engine revs also, if I keep it at about 1-2200rpm it'll stay there, once I boot it , it goes away. My guess is the compressor bearings noise coming through the cabin with the pipes if that makes any sense.
Anyone else have this problem and was it easy to fix?
My Ac bearing use to sound similar to a empty power steering pump whine ,I replaced the bearing still in the car it didnt cost much ,but getting the puller on the pulley was a bit tricky
It was a few years ago I did mine ,pulled my pulley off and went to a bearing shop ,I cant remember if it was a one bearing or two but I didnt have to pull it down
however mine was in a V6 VP not sure what the acess is like in an 8
