Its the climate control sensor fan, a common fault. You get a new one from Renault part no. 8200 093 290 for about £20+VAT. Easy to fit,
Take the interior light down
Look up and you will see two 20 torx screws
Take them out
Drop unit down fit new part then put it all back
10 mins max
Or do what I did and take out the original one, clean with compressed air then lightly oil with WD40, just as good. Hope this helps
