Could you tell me the functions of the S1 and S2 set screws on the drive motor assembly. I've replaced the motor, the top is going up and down but the timing and/or lever travel is wrong. The top is not going down all the way and the boot is hitting the rear window as it is folding up out of the way. I need to know if these screws adjust only the motor timing or the travel limit of the actuating levers, and which screw does what. It is difficult to tell by trial and error and an error will be expensive. Thanks

I see your problem, let me do some research and I will repost Friday at 7:00 PM pacific coast time. Dr. Hagerty
