Why Car Heaters Fail (And How We Fix Them)
Your car’s heater works by drawing heat from the engine’s cooling system. When any part of that system malfunctions, your heater may stop working properly. Here are some of the most common causes of heater failure—and how we fix them:
-
Low or dirty coolant: The heater core needs coolant to circulate properly. We’ll check the coolant level and flush the system if it’s contaminated.
-
Clogged heater core: Debris or rust can block airflow. We’ll clean or replace the heater core if it’s beyond saving.
-
Faulty thermostat: If your thermostat is stuck open or closed, it can prevent your engine from reaching the right temperature. We’ll install a new one for accurate control.
-
Blower motor issues: If no air is coming through the vents, a bad motor or resistor could be to blame. We’ll test and replace these parts as needed.
-
HVAC control problems: Modern cars have complex electronic HVAC systems. We’ll run diagnostics to detect electrical faults or control head issues.
No matter the cause, our expert technicians will pinpoint the problem quickly and get your heat back up and running in no time.
