A-Premium Multifunction Switch for GM Trucks & SUVs — 18‑Pin Combo Switch with Cruise, Wiper & Turn Signal

The A-Premium Multifunction Switch is a direct-fit replacement stalk assembly that restores turn signals, headlight high/low, wipers, washers and cruise control functions for many GM trucks and SUVs.

If the combination switch on your steering column is worn, cracked, or no longer sends signals to lights, wipers or cruise systems, this A-Premium unit offers an OEM-style alternative. It replicates the original lever appearance and markings, mates with the factory 18-pin connector, and bolts into the stock location so you can return routine controls to working order without extensive modification.

Which vehicles will this multifunction switch fit?

This switch is made to fit a wide range of GM vehicles from the early-to-mid 2000s that were equipped with cruise control. Always confirm compatibility using your vehicle year, model and the reference part numbers before ordering.

• Chevrolet: Silverado 1500/2500/3500 (2001–2007 variants listed), Suburban, Avalanche, Tahoe, Trailblazer EXT, SSR.
• GMC: Sierra 1500/2500/3500, Yukon/Yukon XL, Envoy series, Jimmy (2002–2009 ranges).

How does installation work and what should I expect?

Installation replaces the original stalk assembly and attaches near the steering column using the factory bolt points. Basic disassembly of the upper and lower steering column panels is required and the unit plugs into the existing 18-pin connector — no cutting or splicing when the match is correct.

• Placement: mounted at the steering column near the wheel, standard replacement procedure.
• Connector: 18-pin terminal designed to mate with factory harnesses for models listed.
• Attachment: bolt-on installation, tilt steering column down and remove panels to access mounting points.
• Voltage: 12V system compatible with standard GM electrical architecture.

What functions does this switch restore and how durable is it?

The A-Premium switch restores lane-change and turn signal operation, headlight high/low beam control, windshield wiper and washer operation, plus cruise control on/off and set functions. Built from high-impact plastic with corrosion-resistant materials, the lever aims to match OEM look and markings while offering extended service life over a worn original.

• Controls: turn signals, headlamp high/low, windshield wiper/washer, cruise control operation.
• Construction: high-impact plastic for strength and wear resistance.
• Finish: OEM-style appearance with matching markings for a factory look.
• Longevity: designed for repeated operation and corrosion resistance at the mounting and connector points.

Are there any installation tips or parts to verify before purchase?

Before buying, verify that your vehicle was factory-equipped with cruise control and compare your existing part number or connector type to the provided references. Keep tools ready to lower the steering column and remove panels; having the vehicle battery disconnected while working on the column is a common safety step.

• Confirm cruise control presence and year/model fitment to avoid mismatches.
• Compare connector and reference part numbers listed with your original part.
• Use proper trim tools to avoid damaging column panels during removal.
• Disconnect the battery when working near the steering column to prevent accidental airbag deployment or short circuits.

Who this is for: This replacement is aimed at owners, mechanics and DIY enthusiasts who need a reliable, direct-fit multifunction switch for compatible GM trucks and SUVs from the 2001–2009 era. It’s appropriate for vehicles with a failed or broken stalk that requires an OEM-like appearance, complete function set (signals, headlights, wipers, cruise) and straightforward bolt-in installation using the factory harness.
