Hello, I have a 2012 Toyota Prius V with 169k and I have having an issue with the vehicle with having no heat in the vehicle. All fluids are topped off and bled properly, engine head is holding proper compression, and there are no codes in any of the modules. Car gets hot from the exterior all the way up to the boxes at the firewall. Vents/blend doors seem like they are turning over properly, and a/c is ice cold. Anyone ever experience this issue?
My guess: Since there are no codes, I'd look at either a temp sensor (wouldn't there be a code tho') and/or a door blend malfunction. The later is typically a mechanical problem so usually no code involved. Sometimes that's as simple as a servo control cable that's become disconnected from the door or the servo is broken. GOOD LUCK!
