General Information

Three types of tailgates are used on G.M. cars. All three have power operated rear windows. The three types of tailgates are as follows: retractable, dual action, and single action. On retractable styles the window moves upward into the space between roof inner panel and outer panels. On dual and single action styles window retracts into tailgate. Dual and single action tailgate windows are operated by a reversible electric motor located in the tailgate. The retractable tailgate window is operated by an electric motor and cable located to the rear of the spare tire well in the right quarter area. Dual and single action windows can be operated by any one of three switches, one on instrument panel, one on tailgate, and one on wheelhouse (optional) for down operation only. On retractable styles the window may be operated from either the dash or by using the tailgate switch.
