993 Cabriolet Top Issues

[CBRacerX]

Greetings,

My 96 993 cabriolet has a top that is stating to be prone to misbehaving. The symptom is a refusal to go down when up, and vice versa. I can hear a relay click in the trunk when I press the top activation switch, but there is no action from the top motors. Wait a few minutes (or longer) and the top will behave normally. Sometimes turning the ignition on or off helps, but not usually. Sometimes the car needs to be driven before this works again. When it works, all is fine.

I think this is an intermittent connection on the power bus to the top relay, but that is only a guess. Anyone have a similar experience that they could solve?

Cheers,

Chris

Check the emergency Brake switch , it is behind the lever in the Middle console under the Cassete holder . When the Top not moves ,see if the warninglight is on .
I had a few Times the wiringharness in the Top broken , than the relais is not getting the info from the locks and it wont move .
The Top-relais itself is under the Dashboard in the Drivers Footwell .
It is a black Box with 4 bigger Plug-ins . It is hidden under the Central informer .

Don't forget the recall for 95-98 993 Cabs. Call your official dealer with the VIN.
It's mainly to fix the header rail motors.
