First try checking the fuse box . If that is`nt it some models have a box under the hood that has many relays in then one of the two is perhaps the problem > I think it`s safe to say that all of the window motors could not have went out all at once.
all four of my windows stopped working all at the same time i have checked the fuse but it was fine . could there be a breaker or something and does anyone know where it is or what it might be
i got my car used so i don't have the owners guide
