Thank you SuperJETT. I have the same problem on my 2010. Using a meter I could see the 12 volts for about 5 sec, but the motor did not move. I then tried 12 volts to the motor and the door opened. Great! My final set up includes rigging two wires on the motor connector. With a Radio Shack accessory connector with push in wire connections, I open the door with a brief connection to my accessory connector on the dash. That opens the door. To close I reverse the polarity , plug in to accessory, and the door closes. No need to keep it connected to 12 volts so I feel safe. Only two of us, but sometimes I need rear cooling.
Now to learn about control modules. That may not be in my future, but I'd like a price.
Thanks again, Marty
