Hi,
I had the same problems with my 2360's electric deflector actuator, drove me crazy. When mounted per the factory method water leaks down to the gears through the shaft which obviously doesn't have much of a seal and then freezes solid. You'll need to take the casing off the gear end of the actuator and dry it out, re-grease and install the unit upside down. There are some minor clearance issues in this orientation which are easily fixed with some spacers. I've had no problems since.
These items are what I would consider pretty much pure profit for the dealer. Considering the cost I was very disappointed the actuators aren't even sourced to operate in the conditions of the intended purpose.
