740256 Left Hand Marker Switch Electric Window Switch for 2001-2011 Freightliner Columbia Models application

It controls the left hand marker lights and the power window function in compatible Freightliner Columbia interiors. Replacing a worn switch can restore reliable operation when marker lights or electric windows become intermittent. It’s designed as a direct-fit Freightliner Columbia interior switch for the specified model range.

It’s intended for 2001-2011 Freightliner Columbia applications as a left hand marker switch and electric window switch. Compatibility can still vary by cab/dash configuration, so confirm the part number match before installing. If your truck uses a different connector or switch layout, the correct Freightliner Columbia window switch may differ.

Disconnect vehicle power, remove the dash bezel or trim as needed, unplug the old switch, and connect the new electric window switch in the same orientation. Snap or fasten the switch into place and verify marker lights and window operation before fully reassembling the trim. If there’s any sign of heat damage at the connector, repair the pigtail to prevent repeat failures.
