Product Details

Four Seasons 33106 is an A/C accumulator for HVAC systems that use a receiver-drier style accumulator layout. It is built as a complete unit in aluminum and includes the correct port provisions for service and switch connections. This part cross-references UAC RD1689C for the same application. For shoppers searching for a 1994-1995 Chevrolet Lumina APV A/C accumulator, 1995 Chevrolet Lumina Van accumulator, or 1994-1995 Pontiac Trans Sport accumulator, this part number is a direct match for the listed rear-A/C applications. The Four Seasons 33106 also aligns with the 1994-1995 Oldsmobile Silhouette accumulator application.

What It Helps Address

• Moisture buildup in the A/C system
• Restricted refrigerant flow caused by a worn accumulator
• Leaking O-ring sealing points at the inlet or outlet
• Faulty service-port or switch-port housing on the original unit
• Poor A/C performance in rear-air-equipped minivans

Installation Notes

Verify the inlet and outlet fitting style, thread size, and switch-port configuration before installation. Replace the sealing O-rings with the correct green O-rings specified for this unit, and inspect the surrounding A/C lines and connections for wear or contamination. Mounting hardware is not included, so reuse or source the required hardware as needed for the vehicle.

Quality Assurance

Four Seasons 33106 is engineered to meet or exceed OEM specifications for the listed applications. The aluminum construction and OE-style port layout support a direct-fit replacement approach for service work on compatible Chevrolet, Oldsmobile, and Pontiac rear-A/C systems.
