Start the engine, engage the A/C, and look at the compressor to see if the
center section of the pulley (the clutch) is turning.  The "line of tar-like
goo" implies to me that the compressor has seized instead of the clutch failing.
On most cars (don't know about a 97 Breeze specifically), you can turn the
compressor over by hand with the engine not running, by turning the clutch (but
not the pulley).

But, even replacing a clutch generally requires special tools, and hence the
attention of a specialist.  And it's actually against federal law to try to
replace a compressor without the proper refrigerant recovery machine.
