Good day,

Recently , I noticed the passenger side temperature became warm without any changes on temperature control set at 24⁰C.
I had to lower the temp.to 19⁰C to get it back to cooler temperature.
What could have caused this anomaly?

Thank you and happy holidays!

 

The blend door issue is a known one, apparently you Americans got a 10 year warranty or a recall or something on them too? A search should produce some results. I need to crank mine up to 28*C to get any warmth out of mine but I'm not bothered.
Merry xmas!
