I was driving home tonight in my 2014 focus and had the ac on and I noticed the air wasn't bowing hard at all changing settings nothing helped. The blower was running like normal but hardly any air. I shut it off for about 15 minutes when I stopped. And when I restarted again it was fine. I did have to go through a minor stretch of road with water over it not a bunch but enough to hear it on the bumper as I passed through. I'm not sure if that is relevant though. Is this maybe a somewhat common deal? It's under warranty but I don't want to take it in when It's working because I know that'll be a waste.
