Most often, the Webasto heater does not start because there is not enough voltage in the onboard network. This signals the yellow light on the panel. If the voltage is normal, the control of the heater may be hung.
To restart the system, and check it for health, No. 17 (located in the fuse box on the right), take 5 seconds, then insert and start the car. After that, we need to remove the safety catch on the working machine and put it back in a few seconds. It is not recommended to pull the glass on the heater itself, as it may be problematic to attach it back to cold weather.
