Cabin Air Filters
Anyone change them DIY? I know one is in the engine compartment, passengers side firewall, under a trim piece. Easy to get that one. But it seems there is a second one in the "blower housing". Any idea where that is? I know the OLDER GLS' you could get to them all (all three) via the engine compartment going through a single housing cover. Not sure on the post 2020 x167 OR if there could a yet another one lurking in the back somewhere....

Following as well for the Kool-it.
It's supposed to go up the drain tube from underneath the car, but we all know how much fun that is not to do. I know in my 212, it's pull the filter from behind the glove box and stick the tube down the tunnel piece that goes towards the center stack of dash and fill it up. I've done that a few times, always works for several months. Some nasty looking crap sitting on the ground when it's done!
