Sometimes there is a simple fix if you find a convertible that the top can only be lowered or raised by hand. Start by pushing the ‘top down” button. If you can hear the actuators above the windshield and the top will release, you are half way there to an easy fix. Nine out of ten times the problem is that one or both of the connecting rods on the top stack hydraulic cylinders are broken.
You can remove the connecting rods without removing the interior panels below the side windows. Simply get a couple of small vise grip pliers and unscrew the broken connecting rod from the cylinder shaft. Re-attach the connecting rod with the clevis and cotter pin to the top frame. These are only about $8 each.
