Good morning,
It sounds like the compressor has locked up.

When you replaced it last year, how much oil did you install in the compressor before installing it on the car? Lack of oil is the main reason for compressor lock up.
You will need to replace the compressor, dryer, orifice tube and flush the system. Most likely there is debris from the lock-up in the system.

REMOVAL
CAUTION: To prevent refrigerant contamination, if you are installing a new A/C compressor because the A/C compressor has failed internally, you must carry out the following procedures:
If Rotunda A/C Flusher 014-00991 or equivalent is available, carry out the Flushing general procedure. See: Heating and Air Conditioning > Procedures > Air Conditioning System Flushing
If Rotunda A/C Flusher 014-00991 or equivalent is not available, carry out the Refrigerant System Filtering after A/C Component Replacement general procedure. See: Heating and Air Conditioning > Procedures > Refrigerant System Filtering After A/C Component Replacement
Install a new A/C evaporator core orifice. For additional information, refer to Evaporator Core Orifice.
NOTE: Installation of a new suction accumulator/drier is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator/drier.
