Standard Ignition DWS2090 front left door remote mirror switch for the 2014-2015 Lexus GS350 and other vehicles groups the driver's window, lock and mirror controls in one switch. The part is also listed as a power window switch, and it works as a master switch.
A worn or failing door switch can show up as a window that will not move, a mirror that will not adjust or lock buttons that do not respond, though other causes are possible. Before replacing it, look over the switch face and connector with the engine off for cracks, sticking buttons or residue. A shop can test the circuit.
The 2014-2015 Lexus GS350 and the 2014-2015 Lexus GS450h each take one of these front left switches; the front right is a separate part. The switch is built as an OE replacement for these Lexus models.
