Hello Ronzara,

Here's more or less what you need to know about AC systems. 1. The condensor or evaporator are glorified radiators. They don't have moving parts.
2. The orifice is, well, an orifice.
3. The compressor has all of the moving parts. If you have metal shavings in your system, you must be generating it there.
4. The clutch mechanism is working if it is engaged while the AC is on and the system is charged with freon. Just make sure that the entire pulley is spinning on the compressor when it is on. If it is not engegaing, you will see the outside of the pulley spinning and the inside of the pulley will be stationary.
5. The accumulator is a sump. Often it has a desicant (spelling?)in it. If your system is exposed to atmosphere for a long time, you need to replace it. Typically, you are stuck replacing the accumulator with it as it is impossible to remove (on GM units at least).

So to troubleshoot, verify that the clutch is engaged. If not, find out why. Could be due to the leaking sensor. If it is working fine, then you most likely have a bad compressor. The low pressure side should be about half of what it is currently. The metal shavings are indicative of a moving part grinding, so again, this points to the compressor. If you replace the compressor, plan on replacing the dessicant with it. Before doing that though, try blowing out the system from the high side compressor outlet with compressed air. You might actually get some of the shavings out.

Good luck.
