I have a Convertible, when I bought the Saab the roof was operated manually, the previous owner had rewired a switch in boot to lock down storage area for soft top hatch and pull lever to lock top. One cylinder is leaking on the right hand side. I rang the previous owner and he said roof did not work that why he rewired a switch in boot area. I found the Micro switches one in each side, they appear operate okay. There are two cables rolled up inside rear hatch that covers area to store soft top, what are they for?
