BobR07Z , my motor looked a little worse than yours when I pulled it out of the roof drain cavity. I did a little research on cleaning electric motors. I pulled it apart and sanded the copper contacts, put it back together and it works.
You pretty much did everything I did, when I relocated the motor to the trunk I got pressure in the lines by moving the top manually a few times, but no movement with the motor. (I can hear it spinning.) At one point I manually closed the top halfway and could not move it up or down by hand the pressure was so great. I had to pull the red manual switch to release the pressure.
Do you have any idea why the motor works, the lines get good pressure, but there is no movement?
