What Happens When a Chevy Heater is Not Working?

Chevy heaters can work by using electric heating elements or gas heating elements. Gas is more efficient but it also consumes more fuel.

Broken Boiler Motor

This is one of the most common problems in all vehicles. If the motor is broken, the heater cannot work properly. The whole system works on this motor and it cannot run without it. When you find out that the motor has a problem, it is better to replace it with a new one.

Damaged Heater Blower

The heater blower works to move hot air from the inside to the outside of the cabin. When you notice that there is no movement, it means that the blower is damaged or jammed up somewhere. The best thing to do in this situation is to replace it as soon as possible.

Wiring Issues

When the heater is not working, it can be due to a wiring issue. The wires are damaged and they are not making proper contact with the heater elements. This problem can be solved by replacing the wiring harness.

Low Coolant

Low coolant makes your car heater run very slow and this will lead to many issues. This can also lead to a very high engine temperature. If you notice that your coolant is not working properly, it is better to get it checked at the nearest garage.

Bad Thermostat

The thermostat is an important component of the heater system. When this is damaged, it will not let the heat reach the cabin. Replacing it will be the best option to fix this problem.

Leaking Heater Hose

The heater hose is connected to the heater core and it has a very important role in the heating system. It is connected to the water pump and it will take all of the water from the tank.

If this hose is damaged, it can lead to a huge leak and this can affect your Chevy Equinox heater. It is better to replace it as soon as possible.

Dirty Air Filter

When your filter is dirty, you will not get any cold air inside of your cabin because all of the air will be blocked by dust particles and other debris there.

You need to change your air filter regularly because dust particles can build up over time and cause issues in your car’s heating system.
