AIC trouble

Yea mine doesn't look like that unfortunately, but I found it and put the IAC on no problems so thanks anyway. Now about that little black thing that spins on the top of it, what does that do? I've turned it while the car is on and nothing happened at all.
just a plastic dust cover.

I think it's a cover to a pressure release valve. :shrug:
