Four Seasons 3919N A/C Compressor Clutch Assembly

The Four Seasons 3919N is an A/C compressor clutch assembly for a vehicle air conditioning system. The clutch engages and disengages the compressor from the engine drive belt. This lets the system cycle refrigerant on demand and keeps the compressor from running when cooling isn't needed.

Key Points:

• Part type: A/C compressor clutch assembly, also called an AC clutch or compressor clutch kit
• Brand: Four Seasons
• Manufacturer part number: 3919N

A worn or failed clutch can cause weak cooling or an A/C compressor that won't engage. Replacing the clutch assembly restores that engagement.
