Here’s how your car heater is supposed to work:
But sometimes your heater stops on Step 2. Something breaks in your vehicle’s HVAC system or disrupts coolant flow from your engine radiator. Bundle up and head to Midas.
Our Midas Auto Service Experts® take the time to thoroughly explain why your heater just won’t heat, and discuss the best options for your budget. We’ll provide a written estimate before making any repairs. Request an appointment today.
Cold air from your heater is normal for the first few minutes of operation. If the air from your vents doesn’t heat up shortly, you’ve got a problem with your heater or your coolant. Your heating system borrows coolant (water + antifreeze) from the engine radiator, so if there isn’t enough coolant for both systems, the engine gets the available coolant. Another possible culprit: your engine’s water pump is failing to recirculate coolant back to the radiator – again leading to a coolant shortage for the heater.

A diagnostic car heater appointment should cost $80-$100. Fixing what’s wrong with your vehicle’s heating system ranges from $300 for a simple repair (such as a replacement hose) to $1,000 to replace a major part such as the heater core.
The heater core is a small, radiator-like device that usually sits behind your dashboard vents. Coolant enters the core, takes in heat, and then exits to warm up the air being blown into your cabin. Here are some common signs that your vehicle’s heater core needs service:
