I've found several common reasons why car door windows may not roll up. The switch button could be worn out or have poor contact, especially in older cars where switch sticking becomes frequent with prolonged use. Motor failure is also quite common, as the window regulator motor can easily overheat and burn out from extended operation. A blown fuse is a simple yet often overlooked issue—just locate the fuse box and replace the blown one. If dust accumulates in the window tracks or the rubber seals deteriorate, the glass can get stuck. Wiring problems aren't rare either, as short circuits or loose connections can interrupt the current. Additionally, malfunctioning anti-pinch sensors may falsely trigger and prevent the window from moving. For DIY checks, try gently tapping the switch or regulator first. If that doesn't work, seek professional repair. Regularly cleaning the tracks and avoiding forceful operation can extend component lifespan, since non-functional windows cause significant inconvenience.
