Picture this: it's a frigid winter morning in Harrisburg with over 5 inches of snowfall. But, you're ready to brave the cold. So, you hop into your car, expecting the comforting warmth from your heater. However, to your dismay, icy air greets you instead. And a malfunctioning car heater can turn a winter drive into a miserable experience.

The Top Seven Things You can do when Your Vehicle's Heater Stops Working

By troubleshooting the various causes of your car's heating system, you can identify and address the root cause of the issue. So, in this blog, the experts at Meineke on Jonestown Road in Harrisburg look into how to address a non-functional car heater.

Check the Thermostat

The thermostat is a crucial component that regulates the flow of coolant through the engine and heater core. Therefore, if it's malfunctioning, your car may not be getting the signal to produce heat. So, begin by checking if your engine temperature gauge is within the normal range. And, if not, a faulty thermostat might be the culprit.

Inspect Coolant Levels

Low coolant levels can imped the proper functioning of your car's heating system. So, inspect the coolant reservoir and radiator to ensure they are adequately filled. And, if levels are low, top them up with the manufacturer-recommended coolant mixture.

Flush the Heater Core

Over time, the heater core can accumulate debris and sediment, reducing its efficiency. But, performing a heater core flush can help remove these obstructions. So, follow your vehicle's manual for instructions on how to flush the heater core, or consider seeking assistance from the experts at Meineke in Harrisburg.

Check for Air Pockets

Air pockets within the coolant system can hurt the flow of warm coolant to the heater core. So, look to release trapped air by locating the coolant bleeder valve (if your vehicle has one) and follow the manufacturer's instructions for bleeding the system.

Inspect the Blower Motor

The blower motor is responsible for pushing heated air into the cabin. And, if it's malfunctioning, you may experience weak or no airflow. So, check for any unusual noises, such as squeaks or rattles, which could indicate a faulty blower motor. And, if needed, replace the motor to restore proper functionality.

Examine the Heater Controls

Faulty heater controls can also contribute to heating issues. So check if the temperature and mode controls are responding correctly. And, if not, it could be a problem with the control panel or the cables connecting it to the heater core.

Inspect the Heater Core Valve

The heater core valve controls the flow of hot coolant into the heater core. And, if it's stuck or not functioning correctly, you may experience a lack of heat. Therefore, ensure that the valve opens and closes as needed. And, if not, replace it if necessary.

When in doubt or unable to resolve the problem, consult with the professionals at Meineke for expert assistance.
