Well the motor replacement was not to bad, put to motor in and plugged in the wires and it would only go down, just a click when the up button was pushed,
I took an old cord that plugged into the ciggarette lighter and put some female crimp ends on it and them wired to the motor and ran it to the top. Then closed the door and ran through the initialization sequence and done, it worked perfectly,
Drops the 1/2 inch when the door is open and closes the 1/2 inch when the door s closed. After not getting any response to this issue, If I can be of help to anyone else doing this feel free to ask.
