u can pull out each fuse and check it to see if the little u shaped metal is burnt through. if u dont find a bad fuse inside the car then i suspect that there is a either a fusible link or another fuse in the engine compartment that has blown. understand that a blown fuse is a sign of an electrical problem which means u may have a bad window motor that is blowing fuses. i dont think any other items share a fuse with the windows but i am not positive.
