I had to buy this for my 2003 Dodge Ram crew cab pickup because I could only control the windows from the driver's panel. Obviously, the control lock button will malfunction, resulting in all other doors being locked at all times when opening/closing windows. I've been using only the driver's door to control all the windows for too long. My wife wanted her window up or down, she had to ask. I wanted her window closed but she wanted it upstairs so we'd have to argue about it. For the price, this solved a relatively minor problem that was causing a major headache. Installation was very easy - take a small flathead screwdriver, press down on the old panel, gently pry it off the door. Carefully loosen the cable. Take an old, broken control panel and break it into pieces*. Connect the cables to the new control panel. Install the new control panel back into the door. Make all your passengers happy because now they can control their windows. I don't remember, but don't break this lid if you need to reuse it. Otherwise you need to buy another case.
