Hi, I have searched around the Threads and have found nothing on this subject - I could be blind !! There are some comments on freezing Screens and this is what we done at naturally a cost. When specing out the Juke, my wife specified she wanted a Webasto Parking Heater fitted with a larger battery which I thought to be a bit over the top, but in fact this has worked well and is a god send in the early frozen wintery mornings. We specified the smaller Thermo Top Evo 4 Unit with a Digital Timer #1533 (fitted in car). The heater has 3 programmed settings which can be changed and runs for 1 hour max. We set the Juke heating temp at 29°C ( 84°F), Fan speed at 4 and the hot air set onto the front screen and side screens. There were various offers around the Timer (cheaper version) or Remote, we chose the basic Timer which has to be fitted inside the car and set manually to operate automatically at pre-sets or by pressing a button to start immediately - simple.
The engine and inside of the car is warm and the windows / screen wipers are free of ice and snow.
The cost is reasonably high but safety is also an important part of life. Here in Germany there are numerous regulations regarding cars, one is that you cannot have your engine running whilst you are cleaning your car from snow or ice, also which is logical you cannot drive with frosted up windows. When the Webasto system is not fitted it is back to scrapping the ice ( glass scratches ) or spraying and then when you enter the car the inside windows are frosted if you are breathing.
