Heater blower not working

Hi guys just arrived in France on holiday, heater blower fan all speeds not working, all lit up as normal however no blower on any speed. Any ideas of the issue must appreciated as unable to keep the family cool with no ac fan.

Regards

Paul

Theres a resistor pack attached to the fan unit that fails .its a common failure
Not expensive and a plug in item.access fan by releasing glove box down unclip side catches to allow it to fold fully down get torch head in passenger footwell and look up. But you obviously need the part

You could try swapping the relay with the relay for the rear motor. R10. The rear relay is fitted regardless of whether you have a rear aircon.

The relay is in the same box
