If your A/C compressor is seized or malfunctioning, the best course of action is:
* Repair or replace the A/C compressor: This is the proper way to address the issue.
* Remove the compressor completely: This requires removing the belt, and potentially some other related parts. A mechanic can do this, leaving the belt running correctly without the A/C load.
Attempting to bypass the pulley without proper knowledge and tools is risky and could lead to significant damage and costly repairs. It's far better to consult a mechanic for proper diagnosis and repair.
