when diagnosing the top motor cable using a drill independent of any attachments, should the cable spin freely? mine locks up or there is an audible clicking sound met with resistance for each click.
I checked the transmission gears and the white plastic looks good. Didn't fully disassemble for fears of forgetting how to put it back together.
My main issue is top did not want to close on drivers side. when operating the top there is a loud grinding sound. when removing the drivers side cable from the motor the operation sound goes back to normal.
BTW has anyone tried brand name URO top motor cables? Theres a deal right now on amazon for them
