I bought a new truck so I did not to have to work on it.....

I leave my climate control on AUTO all the time and its always comfortable.

My dealer service didn’t have cabin filters when I ask a while back. Going to make a Genos order soon. What do I need for my 2022 it’s a bit confusing

They sell cabin filters at Walmart and most auto stores. I actually like the Fabreeze better than OEM.
