Moin, I hope you can help me. Our elk is in Lower Saxony and always under a carport, so that an icy windshield has absolute rarity value. Today it was at least a little frozen with the elk, so that my wife wanted to try the front window heating this morning, but then scratched again, because nothing happened. Tonight I wanted to try if you can at least “feel” the disc heating, outside temperature Ca minus 2.5 degrees. In urban traffic, I always felt the disc temperature by hand at the traffic lights, inside and outside. At other electric consumers only the driver’s seat heating ran. Inside I had the feeling that it became minimally warm, but I could also be wrong, because I had only set the ventilation to 0 after about 2 minutes. From the outside there was no difference to feel the side windows. Besides, I noticed that the disc heating turned off after 3-4 minutes independently (have s After what I have read here about the de-icing effect one should also feel the heating power or? Automatic switching off is also in the operating instructions, but this should take place at the earliest after 10 minutes or? Do you have an idea where the error lies? “Does” the disc, if there is no ice and does not work? If it does not work, it would be in the error memory and can be read out, or can one d I hope you have an idea.
