If the compressor is running and the blower is running then I would expect
that you have an internal failure.

Could be the dryer has spread it's deccicant all through the system (rare),
or you've lost all of your gas.

If the compressor is running and quiet I would expect it is simply a gas
problem.

Off to an a/c specialist.
