Why is the heater not working on my Chevy Volt?

If your Chevy Volt's heater is not working, there could be a few potential issues. The most common reasons include a problem with the heating system components, a software glitch, or an issue with the vehicle's electrical system. Let's explore these possibilities in more detail.


Heating System Components


The Chevy Volt's heating system consists of several key components, including the electric heater, coolant pump, and thermostat. If any of these parts are malfunctioning, it can prevent the heater from working properly. Some common problems with these components include:



  • Faulty electric heater element

  • Coolant pump failure

  • Thermostat stuck in the closed position


If you suspect an issue with one of these components, it's best to have a mechanic diagnose and replace the faulty part.


Software Glitches


The Chevy Volt's heating system is also controlled by the vehicle's onboard computer. A software bug or glitch in the computer's programming could prevent the heater from functioning correctly. This might be indicated by error codes or warning lights on the dashboard. In this case, a software update or reset of the vehicle's computer may be required to resolve the issue.


Electrical System Problems


The Volt's heating system is powered by the vehicle's electrical system. If there is an issue with the battery, wiring, or other electrical components, it could prevent the heater from receiving the necessary power to operate. Troubleshooting the electrical system, including checking for blown fuses or loose connections, may be necessary to identify and fix the problem.


If you're experiencing issues with your Chevy Volt's heater, it's best to have a qualified mechanic diagnose and repair the problem. They can use diagnostic tools to pinpoint the root cause and make the necessary repairs to get your heater working again.

Why is my car blowing out cold air when the heat is on?


Low Coolant Level
The coolant (usually a mixture of water and antifreeze) in your engine doesn't just work to keep the engine from overheating: It's also the source of heat supporting the heating system. If there isn't enough coolant in your system, the heater core will blow cold air into your car.



Why is the Chevy Volt being recalled?


As a result, GM will be conducting a recall of Bolt EVs (2017-2022) and Bolt EUVs (2022) to address the risk of battery fires in these vehicles.



Does Chevy Volt have a heat pump?


The Engine Cooling System and Heater Loop The engine cooling system (and heater loop) uses the engine radiator, two 12V variable speed radiator fans, an electric coolant heater pump(12V), a coolant flow bypass valve, a high voltage (360V) coolant heater, and a cabin mounted heater core.
