Hi CMax drivers,
We just took a trip to central Oregon in our 2013 CMax Energi (purchased new April 2013 - now 17000 miles).
It can get hot there, and the A/C was just not cooling the interior. We could hear the fan working on high, but there was almost no air flow from any of the dash vents.
Of course it could have been a computer glitch misrouting the airflow, but I hoped it was something simpler like the cabin air filter. Pulled in at Robberson Ford in Prineville, OR. When I told them we were on a trip and needed to get to our lodging that evening, they helped us right away. A tech crawled into the passenger footwell and removed the cabin air filter, which he found located against the firewall, up in front of the center console. It looked rather blackish. He wasn't sure if that was dirt, or some kind of carbon treatment. At any rate, he put a new one in there, and presto, huge amounts of cold air from the vents!
It seems crazy that this filter would plug completely in just 1 year / 17000 miles of driving. We don't smoke, we don't drive on dirt roads except a few miles on rare occasions, and the car lives in a garage. Could it be such a hyper-effective filter? Or do we need to bathe more often...
Anyway - if you're planning a summer trip to a hot place and haven't been using your A/C much, I suggest you check the cabin air filter.
And I'm giving Robberson Ford in Prineville a "like" for quickly getting us back on the road in comfort.
