Hello, I have a question about the optional front window heating with my FOFI 1,3 Bj 95. When the windows are fogged in the morning I turn on the front and rear window heating. The rear window is free in 2 min, but front does not do anything. How are your experiences with the front window heating? How long does it take for you.? The control light goes on, but no more off (if I don’t turn it off manually). The rear window heating goes off by itself. Who can I use the Iter? Greetings HrTimoS
