The car heater blowing cold air could be due to a malfunctioning thermostat or low coolant level. It is important to check these two components first before seeking further assistance.
A car heater that blows cold air can be a major inconvenience, especially during the harsh winter months. When you’re expecting warmth and comfort, cold air blowing from your car’s vents can leave you frustrated and uncomfortable. It’s important to identify the root cause of this issue in order to fix it.
