Is it normal in the '14 Overland, that the recycled button doesn't lock out outside air at all? Going behind a polluting truck, I smell the bad exhaust on several occasions.
The heat is acting weird too. After heating up strong for a while it goes weak and no matter how you up the temp, it does not heat up. On other occasions, it would blow strong hot air at a stop. I'm wondering if somehow the heat behavior is related to fresh air leakage.
