Is it duel climate and blowing hot on one side?

Put both fans on hot maximum temperature. Leave it for a few minutes then turn it down to the lowest temperature.

I had this once and the temperature sensor needed re-calibrating, IIRC, this was the way to do it. I may be wrong though.....

Try as advised above, plus just double check the state of your expansion tank and coolant level. My heater went haywire when I had cracked exp tank and air bubbles in the system.

When one of my previous S40s did this, I just turned it off and left it overnight, was working properly again the next morning and the problem never reoccurred.
