Have a noise coming from down in the area, louder when the A/C is off than on.
Could it just be the Idler pulley?
Going to change that out but think it's the A/C when it is not engaged and free-wheeling ?
Any input on a solution?

 

Both sound the most plausible. Get one of these and poke around

replace the idler tentioner, bought the one from amazon complete not just the pulley... have to take the bracket off. it was loose, problem was the a/c clutch bearing.
$10 on amazon is 35x55x20 ... (there are several options) .. that pulley bearing is making noise when not under pressure ( a/c off).. easy fix

 

Cool. Good to go for a while.
