Hi guys I have an elantra 2009

since one week it start to make tick click sounds when I shut it down this sound is inside the car and it disapear after 5 minutes but it drive me crazy
I am not sure from where but it seems to me from the ventilation system

could some one help me to fix

Thank you

 

could be your blower fan? have you changed your cabin filter latley?

 

Thank you for reply
Actually I did not replace the filter lately
but this sounds start either I use the AC or not. can I do something to ensure that it is the blower fan

Thank you
