Thanks for the advice. Will be traveling next week and will probably need it.Gentlemen,
I know your frustration!
Recently had the evaporator coil sensor replaced, approved by Genesis engineers.
Haven't had an opportunity to take the car on a long drive, and weather has gotten colder.
Not optimistic that the problem will be solved.
However, at the advice of engineering,
Keep climate control on AUTO, and fan to FRESH AIR.
As per Genesis, the system will otherwise freeze up, and designed to redirect air flow to evaporator coil to defrost.
