hey man...i went down to auto zone today and they pulled the codes for me. it read p0410? also the air stopped coming on completely.the clutch wont engage at all.the pully isnt magnetized either.think its the compresser or the pressure switch?or just changw both being that i will be in that aREA anyway.thanks man. by the way the tapping noise is driving me nuts. could it be that the valves need adjusting?

 

P0410 Is the Air pump. Most likely it is bad.

No Air out of the Dash Vents?
