How do I confirm this switch fits my Toyota Tundra?

Check your original master switch for the replace part numbers 84820-0R040 or 848200R040 and confirm your model year falls between 2007 and 2021. Verify the vehicle is not a 1794, Limited, or Platinum edition, as those trims use a different assembly. When in doubt, compare the connector and mounting points to the photos or consult your vehicle’s parts guide.

• Replace part numbers: 84820-0R040, 848200R040

What features improve everyday driving and nighttime visibility?

The built-in white LED backlight lights the switch cluster for easier identification and operation after dark. The switch assembly is produced from high-grade plastics and electrical components to resist wear and maintain reliable actuation. The master switch returns centralized control of all window motors and the driver’s one-touch functions if originally equipped.

• White LED lighting for low-light use
• Durable molded housing and switch contacts
• Restores master control of all windows
• Driver one-touch function support where applicable

How difficult is installation and what safety steps should I follow?

Installation is straightforward for owners with basic tools, but it requires care around interior trim and electrical connectors. Before starting, disconnect the vehicle battery to avoid short circuits and accidental airbag deployment. Remove the door panel or bezel per vehicle instructions, unclip the old switch, plug in the new assembly, and test before reassembling.

• Turn off engine and disconnect the battery first
• Use trim tools to avoid damaging panels
• Confirm connector fit and secure mounting points
• Test all window functions before final reassembly
