Auto Metal Direct 460-4074-553 74-80 Temp Control, 3-Speed, No AC

Restore proper heater and blower fan operation in your classic Squarebody truck or SUV with this OE-style Temperature Control Assembly with 3-Speed Fan Switch for 1974–1980 Chevrolet and GMC C/K Truck and SUV models without factory air conditioning. Manufactured from all-new AMD tooling, this premium reproduction assembly delivers superior fitment, factory-style appearance, and dependable functionality for your classic GM truck restoration.

Designed as a direct replacement for original non-A/C heater control assemblies, this reproduction accurately replicates the original factory layout, mounting points, control operation, and 3-speed blower switch functionality used in 1974–1980 Squarebody trucks and SUVs. Original climate control assemblies commonly become worn, faded, loose, or fail internally after decades of use, resulting in improper heater or blower operation.

Engineered for precise OE-style installation, this assembly fits directly into the factory dashboard opening for seamless installation during restoration projects, interior refurbishments, or heater system repairs. Manufactured using exclusive AMD tooling for factory-correct appearance, improved fitment, and long-lasting durability.

Fits a wide range of classic Chevrolet and GMC Squarebody pickup trucks and SUVs including C10, C20, C30, K10, K20, K30, Blazer, Jimmy, and Suburban models without factory air conditioning.
