A convertible vehicle has a body with a passenger compartment, a pair of passenger access doors each having a window and a pair of rear quarter windows, all mounted on the body for movement between raised and lowered positions. A folding top is mounted on the body for movement between a raised position covering the passenger compartment and a lowered position opening the passenger compartment. A hydraulic system includes a hydraulic pump, two hydraulic top actuators for raising and lowering the top, and a pair of hydraulic window actuators operatively connected to the quarter windows for raising and lowering the windows with less pressure than required to raise and lower the top. A hydraulic circuit connects all of the cylinders in parallel which enables sequential operation of the windows and then the top. A three-position control switch enables the windows to be lowered and raised when the top is in raised or lowered position by moving the control to respective “down”and “up”positions. The windows are hydraulically locked in any selected position by actuation of a solenoid valve when the control is moved to “off”position. In another embodiment the hydraulic system includes actuators for the door windows. This embodiment features many possible sequences of operation of the windows.

In a convertible vehicle having a body with a passenger compartment, a top mounted on the body for movement between a raised position covering the passenger compartment and a lowered position opening the passenger compartment, and a window mounted on the body for movement between raised and lowered positions, a hydraulic system including a hydraulic pressure fluid source and a first hydraulic actuator for raising and lowering the top, characterized by a second hydraulic actuator operatively connected to the window and operable to raise and lower the window with less hydraulic pressure than required to raise and lower the top, and a hydraulic circuit connecting said actuators in parallel so that the hydraulic system is operable to sequentially raise the window and then the top, and to sequentially lower the window and then the top.
