It is hydraulic. the pump is under the back seat. In a pinch, you can supply positive and negative 12V to it and make it go up or down. A likely culprit is a switch that is operated by pulling up on the emergency brake.
There's also a manual by pass valve. It is accessed from the trunk. On the bottom of the passenger's side, you'll find a small flap in the carpet-like trunk covering - the switch is hiding back there. Fair warning, it is a royal PITA to turn in my car. It's likely somewhat frozen due to lack of use; it bypasses the pump motor so that the hydraulic fluid can cirulate freely. The top is very heavy and difficult to move manually.
