i dunno where to put this...

but when i have the AC on, i hear something rattle or knocking, but only happens when the clutch is up. if i step on the clutch , it goes away... wierd...

the car is a 03 and has no mods. any ideas?

 

Its your throw out bearing. mine does it too. as soon as i push the clutch in it will go away.
