No heat from third row vents

The title says it all. I have a 2013 Honda Pilot and have no heat coming from the rear vents. I only have a small amount of air flow coming through the vents (I can only feel it if my hand is a couple of inches from the vents) and it does not change when setting the rear controls to "low" or "high" for hot air. I used to get noticeably warm air from the third row vents, it has not always been like this. I scanned the computer of the car and got the code B1245: AMD(Rr) Motor Potentiometer Shorted. Would replacing an AC control switch or rear blend door actuator solve this?

B1245
Possible Causes

  • Faulty Rear Air Mix Control Motor
  • Rear Air Mix Control Motor harness is open or shorted
  • Rear Air Mix Control Motor circuit poor electrical connection
  • Faulty Climate Control Unit
What ever needs fixing or replacing appears to be needed at the rear controls, so your looking in the right place.
