  If the Webasto Air Conditioner compressor isn't working, there are a few potential causes. First, the voltage may be below 20 V; in this case, switch on the vehicle’s engine and charge the battery. Another cause may be that the overload has tripped; try switching the air-conditioning system off and then on again. If the error occurs repeatedly, contact the service centre. Finally, the electric motor fuse (75 A) may have tripped; check the electric motor fuse and replace it if necessary.

  If there is no heat output from your Webasto Air Conditioner, consider these possible causes and solutions: 1. The pump may not be running. Start the engine and check the pump connections. 2. The coolant may still be cold. Wait until the engine has reached its operating temperature. 3. The water valve may be closed. Open the valve and check electrical connections if a solenoid valve is used. 4. Water hoses may be kinked or crushed. Eliminate the cause of the fault and repair any leaks. 5. The water pump pressure may be too low. Install an additional or more powerful pump. 6. The air flow rate of the fan may be too low. Select a higher fan power stage.

  If the Webasto Air Conditioner compressor does not work when the engine is switched off, it could be due to the following reasons: * The system is only wired to work when the engine is running: Switch on the engine. * The electric motor temperature is over 96 °C: Switch off the system, allow it to cool, and then switch it on again.
