Take control of your driver-side glass with the Standard Ignition Door Window Switch DWS1804, the front-left power window switch built specifically for Lincoln vehicles. It installs as a direct-fit replacement for the 2011-2015 Lincoln MKX and the 2011-2014 Lincoln Navigator, restoring proper up/down control from the driver's door panel. See the Buyer's Guide tab for engine-level details.
This switch controls the front-left window motor circuit. If your driver's window is slow, intermittent, or unresponsive and a failed switch is the cause, replacing DWS1804 addresses it — diagnose the circuit and motor first, since those symptoms can have other causes.
