how to quiet a noisy car ac compressor

A noisy Car ac is not working diagnosis   compressor can be quite frustrating, but there are a few steps you can take to address the issue. It's important to note that unusual noises coming from your car's AC compressor could indicate a deeper problem that might require professional attention. Here's what you can try:

        Inspect the Belts: Sometimes, the noise could be caused by a loose or damaged belt that connects the AC compressor to the engine. Check the belts for any signs of wear, cracking, or looseness. If you notice any issues, consider replacing the belts.

        Tighten Mounting Bolts: Over time, the mounting bolts that secure the AC compressor to the engine might become loose due to vibrations. Check if the bolts are properly tightened. If they're loose, use the appropriate tools to tighten them.
