My daughter has a 2011 CR-V LX (about 160,000 miles on it). After the car is warmed up and she turns on the heat hot air only blows through the two passenger side vents. Cold air comes out of the two driver's side vents. I did a search on Google and one recommendation was to flush the heater core. I did this by disconnecting the inlet and outlet hoses to the heater core. I then used a water pump and two clear hoses submersed in a bucket filled with a solution of one gallon of water and two small containers of CLR. I let this run in a loop for one hour, flushed the core three times with water, reconnected the hoses, and took it for a drive. Still the same problem. Any ideas on what could be causing this?

I watched the videos referenced above and the air mix motor on the driver's side of my car was not moving the white cam at all when cycling between Hi and Low on the temperature dial. At first, I thought I might need a new motor but first I tried plugging and unplugging the motor several times. That did not work so I sprayed silicone lubricant onto the cam that the motor rotates and let it sit for a few minutes. Tried cycling between Hi and Low again and Voilà, it worked perfectly. Maybe there was some original lubricant in there that was dried or gummed up. Anyway, it works perfectly now. Thanks everyone!
