Hi , On my 2011 mod i had a squek noise coming from the air intake for the rear seat ventilation fan , if i put my finger on the intake cover it stoped , I solved the problem by loosening the reachable clipses in the front of the cover . then i used a anti rattle tape from Volvo that is for sale at any volvo store part nr 1161842 . This tape is very useful for removal of rattle and sqeek noises anywhere inside of the car .
Cut the tape in too small pieces and stick it on to the surfaces that is likely to make contakt even on the clipses in this case . clip the cover back in place and test drive .
