Everytime I am idle, or at a stop light. I hear my engine sort of rev then make a click sound.... it shoudn't be normal right? I was once told it was the A/C but it happens with the A/C off or on. What gives? Does this happen to anyone else? And what was the fix?

Just to let you know the A/C compressor is running in all the hvac positions except for floor.

My truck does the exact same thing. It's because it's low on refrigerant.

Thanks for the info.
So your in New Bern? I 've got a friend in Havelock, her husband stationed @ Cherry Point just got sent out to Iraq about two weeks ago.
I visited about a year and a half ago, real nice state!

Jason, is it running in off also?

No it does not run in the off position.
