If you have a leak somewhere and all the Pag oil has been drained of the system, then the compressor may be shot anyway.
It is a 2000 with 79k miles. I am not sure if it has a leak or not. Jumpering the low pressure switch should have caused the clutch to engage but didn't, so I am sure the clutch is bad. There is also a wired knocking sound coming from the compressor clutch area. The pulley still spins, but the clutch never engages. It is possible that it has leaked down, but without taking it to a shop or getting a gauge set I have no way to tell.

I am fairly certain that the factory system uses r12. If I replace the compressor I would like to just go ahead and do a conversion to r134, which I believe also includes replacing all of the o-rings.

From what I can tell the cost of buying parts and needed tools should still be less than getting it replaced at a local shop.
