The motor seems to be running fine, the air compressor pulley is getting loud like a friction thing, it quiets down if defrost or air conditioning is not used.

Is this something to do with the firing of the motor? Btw haven't done any research on this yet, I just getting 'around to it'.

Because it doesn't seem like a big deal, I cleared them, and they showed upon again one time, then I cleared them and now they haven't so its probably not a big deal, but then again its a nice car/motor, at least now it is.
