Mitsubishi Steering Column Multifunction Switch Replacement

This steering column control unit operates turn signals, headlamps, high/low beam, wipers, and washer on many Mitsubishi models. It keeps lighting and visibility functions at your fingertips, boosting safety and comfort every mile.

Why you need this part

A healthy indicator and wiper stalk is vital for road safety and legal compliance. It lets you signal lane changes, select beams at night, and clear the windshield in rain or snow. If yours is worn or intermittent, replace it to restore reliable control.

How it works

Inside the unit are sliding copper tracks, spring-loaded contacts, and a cancel cam tied to the steering wheel. When you move the stalk, it routes low-resistance signals to relays/BCM for lamps and wipers. The cam auto-cancels the turn signal after a turn. Intermittent wiper speeds are set through stepped resistors and internal detents.

What happens if it’s faulty

Common symptoms: indicators won’t latch or cancel, lights flicker, no high beam, wipers stuck on one speed or dead, washer inoperative, blown fuses, or a hot plastic smell. Driving like this reduces visibility and can damage wiring or relays.

Fitment and quality

Built to OEM specs with durable ABS housing and silver-alloy contacts for long life. Direct plug-and-play connectors ensure a snug fit and clean signal path. Ideal as a genuine-grade replacement for your Mitsubishi.

Install tips

Disconnect battery, remove column shrouds, unclip harness, and swap the unit. Align the cancel tab, avoid rotating the clockspring, and torque screws lightly. Test indicators, beams, wipers, and washer before road use.
