I fitted a new belt for the air con today in my ED XR6. Now when I press the button for air con it makes a weird rattling knock sound. I have had a bit of a look and it may be the idler is not tensioned up properly but the belt only moves the 8 or 11mm that the gregory's manual said it should move when about 10kgs of force is place on it. It is definitely the air con compressor or something as when I turn it on it makes the noise and when I turn it off the noise goes away.

The car did not run for ages as I have been overseas, could this have affected the air con system? I have been driving around for about a week and a half now with no problems (besides no air con). The air con works fine when turned on, just makes a weird ratling/knocking sound. It is not a regular knock, but more of an irregular rattle so something may be loose, hence my first thought being the idler.

I don't think this is it (but it may be??? I don't really know), so is there anything else that is part of the air con compressor system that could produce a knock?

Also have an ED, no "knocks" but a lot of "clicks" when idling. It clicks and idles faster for a little while, then clicks and idles normally, and keeps going back and forth every so often.
