non MB A/C question

[Wallknight]

Sorry for a "foreign" car question, but I figure someone might know, and I've come to trust yall.
My wife's A/C on her 94 Chevy Cavalier (R134a) just died yesterday. The night before it worked fine. The past few months, something has been jingling/squeeking in the vicinity of the compressor. NOw, the clutch does not engage (I've not tried jumping it yet). ANy ideas?

If its any consolation, this car is such a piece of #@@%$# that its out of hear come the first good deal on an SD I can find!!
THank you,
Paul
