I took my Prius Two to its first car wash today, afterwards, the air flow from the vents became minimal, almost non-existent. How could this be? The car is barely two months old. Prior to the car wash, I had the AC and air blasting to the highest, I didn't change any fan settings, and now there's barely any air coming out. I can hear the fans churning and running, but there's no air!!! Do I take it to the dealer? Please help!!! Thanks.
