Check your car's electrical system before investing in a new motor for your automatic window. Examine the fuse box for any blown fuses and any necessary replacements. This may solve the problem immediately. Often the switch operating the window may simply be dirty or stuck. Apply contact cleaner around the switch to remove any gummy buildup. If the window is still stuck, there may be an issue with the motor.
