A/C compressor "thump"
Tonight while driving my Bonny (highway, 55-65mph), I noticed a fairly loud thump coming from the front passenger area. At first I thought my passenger was stomping his foot on the floorboard... that'* what it sounded like. He swore he wasn't and said it seemed to be from the engine compartment. The thump repeated every minute or so, and stopped when I turned off the A/C... leading me to believe it was the compressor kicking on and off. But it didn't sound right. Any similar experiences, or ideas of what to check?
