2000 Boxster breaking convertible top transmission cables

[crwarren11]

Hi all,

Over the past 6 months I have now broken 3 convertible top transmission cables (i.e. motor-to-transmission p/n 986 561 717 03).  This is after not breaking any of these cables for the first 19 years of the life of the car.  I believe what is happening is that the motor is being allowed to run too far past the fully open and closed positions (seems most likely the top-closed position as the breaks have occurred 3 of 3 times when the top is closed or closing).   After reading many of the posts about the microswitches that control the power to the convertible top motor, I believe this is likely my root cause.  However, I am unclear which switches I need to check for my model year (2000).  I understand that I have the later-version transmissions which have a switch inside the transmission case and I confirm that this is the model that I have.  I thought this was the switch that controlled power to the motor and to turn off the dash light. But I am not sure if I also have the switch in the B pillar (986 613 767 01) and/or the switch in the roof (986 613 101 02), or if/how these switches control power to the convertible top motor.

 

Many thanks for any guidance you can provide!
