D5-D6:

Normal Operation
The convertible top hydraulic system uses a 12 volt reversible pump and motor assembly. When active, the pump uses hydraulic pressure to extend the hydraulic lift cylinders to raise the convertible top, or retract the hydraulic lift cylinders to lower the convertible top. The convertible top assembly is a floating frame, Z-fold design. The main pivot brackets are attached to the body, and the convertible top frame side rails expand or fold when the convertible top is raised or lowered. The convertible top frame bows attach to the convertible top frame side rails and provide tension for the convertible top material.

Possible Causes
- convertible top frame bows
- convertible top frame side rails
- hydraulic lift cylinders
- hydraulic motor/pump assembly
