Hyundai Tucson owners from 2010-2015, if your driver side window switch is acting up, this replacement is exactly what you need! This is the front left driver side switch that controls all your windows, door locks, and has that handy auto window function. It's made from durable plastic and metal components that have been tested 50,000 times - no corrosion, rust, or sticking buttons. The installation is pretty straightforward if you're comfortable with basic car repairs: use a skid plate to carefully pry out the old switch, disconnect the plug, connect the new one, and snap it into place. Important - this is part number 935712S000, so double-check that matches your original before ordering. Also make sure the pins match your vehicle's wiring harness. The buttons are smooth, the symbols are clear and won't fade, and the whole unit feels solid. It's a non-OEM part but the quality seems really good for the price. Much cheaper than going to the dealership! Just remember to turn off your power before installation and clean any dust from the connection area. If your windows are getting slow or the switches are failing, this replacement will have them working like new again.
