Re: A/C clutch noise
My '06 makes the grinding sound when I first turn on the A/C if I haven't run it for a while. I don't get any kind of smell from it though. It's done it since new. I used to have a Ford based motor home that did the same thing. Don't know if it's normal or not but mine seems to be fine.
