    Well, I am going to be tearing into the tailgate. Replaced the weatherstrips for the glass and found out just how weak the lift motor is. So I will be replacing that lift motor.

    Now, when I picked up the Bronco four years ago, the cylinder operated that back glass. I did not try for over a year and since then it has not worked. No, biggy, just turn on the engine and use the switch in the cab. But I would like to fix it if it is not above my pay grade.

    Does anyone know for sure whether or no that cylinder in the back operates the regulator electrically or mechanically? Does it send current to the motor or is there linkage that might have disintegrated and come apart?

    Not sure what you mean by a cylinder.

    I thought the power rear window would operate like a station wagon power rear window. (Which is the same as a power side window) An electrically operated window motor spinning against a gear in the window regulator. Moves window up and down. Switched be a control switch mounted on the instrument panel or at the rear door.

    It is an electric regulator and motor. There is a switch on the dash that works. The cylinder in the back worked once. I wondering if that cylinder was hooked up mechanically or electrically to the motor.

    Awesome. From the 1990 Shop manual it is essentially the same. The key operates a electrical switch on the inside of the tailgate.

    Six wires to the switch
