Car not putting out heat
Oluseun, that can be caused by multiple errors. Check to make sure that you have enough antifreeze, check the hoses to your heater core, the top one should get hot/warm. Stuck thermostat could also keep it from getting heat. You also want to make sure that your heater fan works, and that the flap servos are working.
