keep me from unlocking my doors in the cold mornings. is there anything made for DC motors (essentially what this actuator is) that you can fill them up with to keep them from freezing up? Here in Texas, that kind of stuff doesn't seem to be talked about much. Plus on newer vehicles, the lock actuator is not hard linked to the locking mechanism like the older cars and keys will still work, but on my car, the whole works is tied together so the actuator prevents the key from being able to move anything if the actuator is frozen. again, this is the actuator inside the door and not the key lock that gets frozen. This is the first year I've had to deal with this and it's rather annoying not being able to get in my car in the mornings.
