check the relay for the damper and the fuse,these dampers can sieze with ice if not lubricated with grease on a regular basis.

theres a solid state controller inside the relay board box,
bolted up by the das, it'll be that

Linkage connecting motor to door often come adrift. Also motor has a heating element which energises below freezing. If this fails damper may not work at very low temps.

Thank you for the advice. The fuse is OK. Check out the other as soon as the trailer back
