Porsche Boxster 986 Convertible Top Mechanical Components

An overview of the mechanical components involved in operating the convertible top on my 1999 Porsche Boxster 986.

Electrical motor spins two cables (housed inside of sheaths) that are connected to a transmission on either side (located behind plastic cover and upside down v bracket held on by 19mm bolt). The rotation of the cables drives a worm gear that rotates gears inside of the transmission, spinning the v bracket which in turn moves the arms attached to either side- the forward arm with a plastic cap connects to convertible top frame and the rear arm connects to the clamshell support arm.

Common Issues:
Cable:
1. Not enough cable protruding from the end that connects to motor- should be sticking out from sheath by .5-.75 inches.
2. Cable end rounded off- should be square for motor to have enough bite and spin it
3. Cable comes apart inside sheath

Convertible top arm: (red cap in video)
1. Plastic end snaps and arm disconnects from forward most ball socket to convertible top
(Inspect foam lining for any gouges or holes if this happens so that water doesn't leak into cabin and cause expensive electrical damage)
2. Metal arm bends
3. Rubber grommet is worn
