for a while now they haven't been working and i have always thought that it was this blue box inside the driver side door cause its labeled "door lock unit" so i ordered a new one and i go to put it in today and they still dont work so i am confused about what it could be. also, a while back before it stopped working i remember that the locks wouldn't work but then randomly i would press the button and they would work, so it was kind of intermittent before the power locks totally crapped out on me. any suggestions? i checked the fuses under the hood and dashboard.
