Get a matching plug from your hardware store and hook it up to a 12V car battery now where the motor is on the tube you then can power the motor directly by-passing the switch/wiring and such then work your way backwards. mine was a result of the half-azzzed shotty workmanship of our local CC dealer in Harrow who installed the awning,,, I wish I had taken pictures,,, they basically used cheapo-fillip wire connectors without any protection from the weather so after finding the fault I re-did things properly and have been good-to-go since! Another friend's dometic awning went as well and it turned out that the supply wire that ran up the awning arm had broke at the upper elbow from being bent repeatedly sorta' like a coat hanger, easy fix.
