Hello people When I started my thick one today, the blower engine didn’t run at all. He was just dead, although the beam was standing on the top of the display. I could also turn on the adjustment wheel as much as I wanted, the blower didn’t start at all. Then, a little later, it started suddenly. However, it always went on and off and off turned high, then low again etc.. That went for quite a while as if the engine had a wobble contact or would get false values from a control unit as far as the speed was concerned. Again 5 minutes drive later everything went back to normal. Fans turned evenly as I could set this on the wheel. Also, the automatic function goes. Then when I turned off the car, the solar function starts. Here I noticed that the fan rotates extremely slowly and strangely ratters as if it had a bearing damage. It also promotes hardly any air in solar operation. But when the engine started out blindly, that’s what I thought it would be normal. Can also deceive, since the side noise of the V8 can’s not be so bad or something else?
