Another update. During a very cold day a week ago (25 F, windy, some humidity, no sun) I had the lift gate finally dead completely. Saturday evening, went to the local dealership on my way home and the service department was closed. Asked sales guys to test it for me just to make sure. Two guys spent 20 min trying different things before giving up. They were looking to hear a click inside to make sure it is not frozen but got nothing. Gave me their cards to tell the service people to call them. Went to service today (20 F, sun, dry weather) - stupid thing worked well, but with sales people involved got a loaner car and dealer is replacing the rear switch after calling Honda.
