+1, No solution since way back, Dealer and Ford Teck's, have no clue why it doesn't
turn on. One day when it was 28 degrees and the windshield was cover with snow.
By the time I clear the snow off the 2011 MKx, doing the wind shield last. The seats, steering wheel, and HVAC worked as they should. The day before this it was 18 degrees and nothing worked when remote starting the vehicle. So I've learned to live
with it the way it's. Best wishes!
