Product Details

Global Parts 1411320 is an A/C accumulator used in the HVAC system to help keep moisture out of the refrigerant circuit. Moisture control is critical during A/C repair because an opened system can introduce contamination that affects cooling performance and system reliability. This part cross-references Four Seasons 33170 and 75276 for the same application. It fits 1980-1984 Chevrolet G10, G20, and G30, as well as 1980-1984 GMC G1500, G2500, and G3500, with application notes for vehicles without rear A/C on 1983-1984 models.

Common Service Issues

• Moisture contamination after A/C system service
• Reduced cooling performance from a compromised accumulator
• Need for replacement during compressor, hose, or line service
• System contamination after opening the refrigerant circuit
• Fitment-specific replacement for GM G-series van A/C repair

Installation Notes

Replace the accumulator whenever the A/C system is opened. Verify vehicle fitment by year, make, model, and notes before installation. For 1983-1984 Chevrolet G10, G20, and G30, and GMC G1500, G2500, and G3500 applications, confirm the vehicle is without rear A/C and check the listed switch and pigtail notes before ordering. Part number 1411320 should be matched to the original service configuration.
