I have been having typical top problems with my 99 Boxster's Top Mechanism. I have actually broken 2 of the cast aluminum arms. I have checked all the microswitches and have synchronized the top motors. My main question is - what makes the dash light for the top go out. The top normally open or closes then right at the point of finishing opening or closing, the motors start to slow down and if I keep pushing the button the dash light eventually goes out but the last time I did this I broke another arm. Any advice?? Thank you, JMP
