Detailed Description

Nissens part number 891101 is an A/C compressor engineered for Mercedes-Benz HVAC systems that require R1234YF refrigerant and a 6SAS14C compressor type. The compressor’s critical components, including the pulley, clutch, hub, bearing, and wobble plate, are designed to support consistent pumping performance while limiting noise and vibration. This makes it a practical replacement for Mercedes-Benz A220, CLA250, CLA35 AMG, CLA45 AMG, GLA250, GLA35 AMG, GLA45 AMG, GLB250, GLB35 AMG, and A35 AMG models listed in the fitment data.

This part cross-references Monroe Shocks & Struts (e.g., ACP1719000S) for the same application. Part number 891101 is also referenced for OE-style replacement searches where Mercedes-Benz compressor fitment is required.

What This Compressor Helps Address

• Weak or inoperative cabin cooling
• Noisy compressor operation
• Excessive vibration from worn internal components
• Loss of refrigerant pressure due to compressor wear
• HVAC performance issues in R1234YF-equipped Mercedes-Benz systems
