A/C clutch
Installed new A/C clutch on a 1993 Mercury Villager. Now when engaged, A/C make cold air, but clutch makes very audible clicking noise. When disengaged, clutch drags intermitently and there are metal filings on the clutch surfaces and a lesser clicking noise. I am a "Haynes Manual" mechanic and there is are no instructions in any of my manuals on installation procedure. What went wrong? Thanks for any help.

why did you change the clutch to begin with, if it was discolered from being hot and making noise it is usually caused by the compressor trying to lock up which as a result burns the clutch up in no time.
if it was done just because of an electrical failure of the clutch you may not have your air gap set correctly.

The outer plate has to be shimmed for the proper clearance but that doesn't explain the clicking nois when engaged. That's probably the compressor knocking. Clutches fail for a reason and the reason is usually the compressor. Also the heat generated by the overheated clutch will usually ruin the front seat. That's why we always change the entire compressor unless the problem was just a weak coil. Coils don't burn up for no reason. You need to find the original problem.
