My car has an automatic climate control system. The heater works only when i set the temperature to 32 and if i bring it down to 31.5 the blower fan speed reduces, but the heater does not work. In my opinion the blower works perfectly at all settings but the heater works only in the max settings. Can you please help with this issue?
