Maybe your A/C compressor clutch is seizing? Does it start to rev on its own at all when your at idle?

no it doesnt rev on its own. just when i turn on the a/c the belt starts floping and when i drive it drives fine and when i idle again it flops again. then w/o the a/c on its fine

I would guess the tensioner is about to break or is going bad. Try pushing on on it and see if it is hard or easy to move.

This is strange... Is your check engine light on or anything?

Only happens when the A/C is on eh? Probably the A/C compressor. If it were the tensioner it would happen all the time. It's a rather expensive part(400+) to replace plus you would have to refill ur refrigerant after install. But of course, have checked out by a tech to confirm this.

I had check engine light come on it wsa a P0507 so i did idle relearn and another gas pedal dance and after about 2 weeks the light went off. The belt flopping issue still exists and have been to this could be a vacuum leak though i have not been able find locate it yet

Still dealing with this issue. Seems strandge that only 2 altima owners experience this. They must have been built on a friday
