If your Corvette's horn is erratic or unresponsive—especially in steering systems with tilt or telescopic functions—the fault often lies with the lower horn contact. Wear, corrosion, or misalignment can interrupt electrical continuity. Installing a fresh, OEM-style brush restores reliable horn function, preserving both safety and authenticity. This authentic replacement lower horn contact brush (GM #3994426) is engineered for 1969–1982 C3 Corvettes equipped with tilt or telescopic steering columns. It's a direct-fit reproduction featuring a steel and plastic contact assembly designed to maintain consistent electrical connection with the horn button through steering motion. Mounts securely on the underside of the column hub for dependable horn activation.
