C4 MK2 heater blower not working

Hi all, so picked up my car last night from airport carpark after being away, and noticed my fan setting was on max, but the fan isn't working, (i presume the carpark attendand has been sitting in there with the aircon on) it was working fine on my journey there, any ideas what this could be?

Thanks

If somebody else had access to your car have you checked if anything has been removed from it ?
