Hi, I have a 2012 GL450. It seems every summer the AC emits a smell. It is hard to describe it. It smells like moisture chemical. After driving, my neck and nose would get irritated and itchy. I also noticed the back, behind 3rd row area is the strongest but couldn't located where. Please note this is not the bad socks smell. It smells like chemical. I've tried blowing with ac turned off before stops the car but didn't do anything to mitigate the smell. Also changed cabin filter every 6 month, didn't help either. Dealer tried using the refrigifresh but didn't help either.

Anyone could help? Thank you so much!
