If your Mazda MX-3's heater is only blowing warm air, it could be due to a few common issues. First, check the coolant level; low coolant can prevent the heater core from receiving enough hot coolant. Additionally, a stuck thermostat may not allow the engine to reach the proper temperature, resulting in inadequate heating. Lastly, a malfunctioning heater control valve or a clogged heater core could also restrict hot air flow.
I believe that you fill it with coolant, as the tank's name suggests.
Too little coolant, or a plugged coolant line.
