In the last 2 days the following happened to me after the late shift. When I got to the car after work (against 22:10) I noticed that with some other cars the front windows were already lightly blown. My front window was quite slightly “natched” speaking, not really piped but probably just before. I wiped myself in the car with the wipers and had clear view – after that I drove off, ventilation I also directed to the window. After about 20 0 m suddenly I had zero sight, really zero sight – I ran right and had to wait about 1-2 minutes until the disk was free and I saw something again. Maybe it’s also because the disk is fogged from the inside after the start of the ride, I don’t know. This night I had the mat on the disk but this morning the same thing happened to me as yesterday evening. What’s the reason ?
