Now I have something to think of What can it be if the blower doesn’t work? Although it comes warm through the wind. The keys come the brighter when you press on it, but no matter if 1,2,3,4 that doesn’t work. I saw there is a relay for that it can be? And a mechanic once said there would be below the windscreen wiper of the engine and there you would have to solder something out and again. What do you think about it?
