... I was able to remove the clips and pins on the levers and now the clam shell can be lifted by hand. The motor now spins the transmissions freely. So, there must be something (micro switch) to tell the motor when to stop? Is this the micro switch (yellow) and can it be adjusted. It does click, forward and backwards. Thanks. Oh, by the way. Is this held on with pop rivets (red) and the top trim piece held on by pressing into the rubber grommets (blue)?
