Replaced air compressor in1999 mercury mystique replaced fuses worked for few minutes then stopped

If you mean A/C compressor, there are safety switches for high and low pressure. You need to evacuate the A/C system with a Vacuum pump and then fill it with Freon. If you already did this, chances are that when the Freon stabilized, it was either too high or too low of a pressure and the safety switches worked.

Put in air compressor in 1999 mercury mystique worked then stopped

You must have recharged the unit? Or replaced the compressor unit? Some have an "overload" relay, it may have caused one of the fuses to blow.

99 mystique making weird noise when i turn on the a/c, like if some bearing was bad

chances are there is a bad bearing, inside the air conditioner compressor. where the belt goes there is a centrifugal clutch, listen close to there and if's from there, you need a new compressor.

1996 Chevy Tahoe air conditioning not blowing cold air

That "thing" is part of the compressor clutch. When it’s spinning the clutch is engaged, when it stops the compressor is off. If it’s constantly cycling, you probably don’t have enough freon in the system. But remember, however the gas escaped before, it will escape again, unless you fix the leak.
