GMC Acadian Cabin air filter location?


I have a 2007 GMC Acadia and I need to replace the cabin air filter, where is the filter located at? I look behind the glow compartment but there is none. Did any body replace one? Is it a dealer item, it is not available in the parts store?



Just looked at the owner’s manual for that vehicle, there was no mention. I don’t think it has one.
