Today, I found that my 2007 Mazda 5 front passenger window does not work. When I press the buttons of both sides (driver and passenger) for opening the passenger window, nothing happen. I did not hear any sound from the door. It doesn't whether I locked or release the window, pressing the button causes nothing. What is the problem? I think my first job is to check if the fuse is broken; however, where the fuse is located? I inspected the fuse box under hood and it seems that there is none that controls the window. Do I needs to replace the window regulator or motor? Thanks.
