Detailed Description

Universal Air HV1002C is built for HVAC temperature control systems that use vacuum actuation to regulate heater coolant flow. In applications such as Buick LeSabre, Chevrolet Caprice, and Oldsmobile Cutlass models, the heater valve vacuum function is part of the system that helps the cabin heater respond correctly to control inputs. This part number, HV1002C, is cataloged for broad coverage across 1976-1991 GM passenger cars and wagons listed in the fitment data.

This heater valve vacuum component is a practical service replacement when diagnosing temperature control complaints on classic Buick, Chevrolet, Oldsmobile, Pontiac, and Cadillac platforms. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems It Can Address

• Heater output stuck on hot or cold
• Vacuum-controlled temperature door or valve response issues
• Inconsistent cabin heat regulation
• Loss of heater coolant flow control through the HVAC system
• Fault tracing on classic GM HVAC temperature control circuits

Installation Notes and Tips

Verify the vehicle’s HVAC system uses a vacuum-operated heater valve before ordering. Compare the original valve routing, vacuum connections, and mounting style to the replacement part number HV1002C. After installation, check for proper vacuum supply and confirm that the heater control responds through the full temperature range.

Quality Assurance

Universal Air identifies this part within its Heater Valve Vacuum product line for HVAC temperature control service on listed GM applications. Confirm fitment by year, make, model, and HVAC configuration before installation.
