The procedure is to disconnect the negative battery cable, locate the underhood bussed electrical center, remove the UBEC cover and the 60 amp heated windshield washer fuse, connect the negative battery cable, test the operation of the windshield wiper system, close the hood, and then make a copy of the Owner Manual Supplement, located at the back of this bulletin, and place it in the glove box.
