Hi everyone, I apologise in advance if this problem has already been discussed, I am new to the forum and  couldn't find it elsewhere.  Skoda Rapid 2017 plate, fan comes on, very loudly, even if car not engine not switched on.   The fan comes on for no reason whatsoever.  Is booked in at garage on Monday but just wondered if anyone knew the reason for this and also if its safe.  Thanks

The fan is mounted behind the glove box and on our 2014 rapid it went noisy and it was the fan blade coming loose so tried gluing it back on which worked as it's only slightly noisy on full now.
