Hello,


Sometimes I can feel the AC compressor kicking on. (I have the setting on "auto")
I feel/hear a very mild vibration. This only happens when the car is not in motion. Is this normal or I have to replace it soon?


Thanks in advance!

 

You may want to open the hood to see what is causing the vibration or noise. Both fans on the radiator turn on when you turn on the a/c, so it could be a noise/vibration from a fan.

The serpentine belt has a tensioner on it with an indicator if the belt is stretched too much. You'll have to look in the owner's manual to for a picture on how to read that.

Take a look at the compressor pulley to see if it wobbles when the a/c turns on.
