A heatable vehicle window (e.g., windshield, sidelite or backlite) includes a multi-layer coating formed on a substrate. The multi-layer coating includes at least one dielectric layer and at least one conductive layer. A pair of bus bars are deposited on the substrate over the coating, so that at least the dielectric layer is provided between the bus bars and the conductive layer(s). In order to create an electrical connection between the bus bars and the conductive layer(s) of the coating, the bus bars and/or coating is/are heated to a temperature sufficient to permit the bus bars to reach molten or semi-molten form. Portions of bus bar material then flow down through at least the dielectric layer of the coating (i.e., forming a contact hole in the coating) so as to contact the coating's conductive layer(s). After cooling of the newly formed bus bars, the window may be selectively heated by passing current through the conductive layer(s) via the bus bars.
