Changing a Fuse: Locate and open the fuse box.It should be located inside the car as a part of, or near, the dash. Check your owner's manual to locate that operates the windows. It is not uncommon that the only thing wrong with electrical components in a vehicle is a blown fuse. If this is the case with your windows you will need to replace the window fuse. Pull the fuse straight out of its cradle. Be careful not to twist or otherwise force it. You do not want to damage the cradle or break a piece of the fuse off in the cradle. There are fuse tongs available at part supply stores that can help with this.
You can also perform the test yourself if you have access to a Battery Load Tester, a device which is made for the purpose. The load tester works by placing a specific amount of electrical load on the battery for a specific amount of time while monitoring the available battery voltage. The battery should be fully charged before the test in order to insure accurate test results.
