Mercedes Sprinter Combination Switch – Valeo | NCV3 & VS30 | #9065450310 (2010–2021)

A worn or failing combination switch on a Mercedes Sprinter means losing reliable control of turn signals, headlights, or wipers from the steering column — functions that are legally required and essential for safe operation in traffic and adverse weather conditions. This is the Valeo combination switch for NCV3 and VS30 Sprinters, a direct replacement that restores full steering column control of turn signals, headlight functions, windshield wipers, and related driver control inputs.

What This Part Does

The combination switch — also called a multi-function switch or steering column stalk — is the integrated control assembly mounted on the steering column that gives the driver one-hand access to turn signals, headlight high/low beam switching, headlight flash-to-pass, windshield wiper speed selection, intermittent wiper interval adjustment, and washer spray function. It consists of two stalks — typically a left stalk for turn signals and headlight functions and a right stalk for wiper and washer controls — connected through a common housing that mounts to the steering column shroud. All inputs are routed through the combination switch's multi-pin connector to the steering column module or BCM, which interprets the switch positions and activates the corresponding vehicle functions. When the switch's internal contact surfaces wear, its detent mechanism loses its tactile feedback, or an individual function becomes intermittent, the affected control must be replaced.

Common Symptoms of a Failing Combination Switch

• Turn signals that activate inconsistently, fail to cancel, or don't self-cancel after completing a turn
• Headlight high beam or flash-to-pass function that is intermittent or non-responsive
• Windshield wipers that don't respond to stalk input at one or more speed settings
• Washer spray that doesn't activate or activates intermittently
• Switch stalk that feels loose, wobbly, or no longer has positive detent positions

When to Replace

Replace when a specific switch function is confirmed inoperative at the stalk after ruling out the associated relay, fuse, and wiring harness. The combination switch is replaced as a complete unit — individual internal contacts are not separately serviced.
