I bought a new car in the month of April 2019 but from the past few weeks, I have been experiencing very very hot air coming from all the vents.

The temperature is high to an extent wherein it becomes unbearable and I have to switch on AC (currently it's pleasant outside in my city so AC was not required).

I recently measured the temperature and it was greater than 44 degrees Celcius/108 degrees Farahenite. And I am sure I experienced hotter than this.

So bit worried and wanted to seek an opinion from the experts. Sharing some data:

AC unit type: Automatic Climatic Control

Route: Office to Home

Distance: 6 KM

AC status: Off

Re-circulation mode: Off

Windows: Rolled down

Temperature: 43 degrees Celcius/108 degrees Fahrenheit

  • Have you got the heater switched to hot? – Solar Mike Aug 29 at 18:08
  • Solar, I correctly remember, the temperature knob was at 21 degrees – Anubhav Ramesh Mulchandani Aug 30 at 1:38
  • If the a/c is off, as you state, then you can set 15 degrees but it won’t happen... – Solar Mike Aug 30 at 4:57
  • The automated door(s) that mix cold and warm (or hot) air (and also exclude one or the other, perhaps) is called the blend door. Some cars have one, some 2 or more. Some are mechanically actuated, some by electric motor or vacuum. Sound like it might be malfunctioning... – Jimmy Fix-it Aug 30 at 6:04
  • Jimmy, thank you for giving some insights. This may be a reason but I cannot have a look at it as the car is with the service center. The irony is that both the dealer and the manufacturer are considering this behavior as normal. Could you explain more about blend door? – Anubhav Ramesh Mulchandani Aug 30 at 12:22
