    Here is a supplemental drawing of the system used on the Century and Skylark convertibles which continued to use hydraulic window lifts for '54. Power from the breaker goes to terminal B on all 4 switches. Power to the Hydro-Lectric pump motor solenoid comes from terminal M on all 4 switches. Power to the valve in the window cylinder comes from terminal C on each window switch.

    Pages from the '48-49 Shop Manual attached show the internals of the switch contacts when raising or lowering a window. The switch energizes the pump and the cylinder valve during RAISE. It energizes only the cylinder valve during LOWER.

    The LF switch is a part no 4641074, also used on '54 Oldsmobiles with hydraulic window lifts. Reproduction switches are available from www.fusickautomotiveproducts.com according to their Website.

    54 Buick window switch wiring diagram

    Thank You so much for those diagrams. I have all the windows working now except for the LF. Had to order a hydraulic cylinder. Solenoid was sticking. Thanks Again. T. Brown

    Hydro Electric Pump Assy

    Well, I got the windows working, after replacing the LF cylinder. Now a new problem. Every time I run the top or the windows up and down, it pisses fluid out the weap hole on the pump. I spoke with Paul at Hydro-E-Lectric in Punta Gorda and he said to make sure I did not have too much fluid and I don't. As a matter of fact I even took a little out to see if it would stop. Any ideas? tomb.
