My car doesn't overheat but the air and the heat do not work

Hello, although you could have an engine temperature issue influencing heat -- you should check your engine coolant temperature with a diagnostic tool to start with -- it is more likely by your question that you have a climate control system fault that needs to have troubleshooting performed for. If the doors inside the plenum do not turn properly from hot to cold or cold to hot as desired, then you will not get the temperature air flow desired.
