For the most part, the Chevy Spark is a car that you can trust and that you can depend on. That being said, when the Chevy Spark begins to make strange noises, then you need to pay attention to what it is that is going on with your vehicle.

This can be extremely dangerous if not dealt with quickly and correctly.

One of the most common issues people experience when driving their Chevy Spark is the heater. This is a very common issue that occurs in many Chevy Sparks but is easily fixable.

What Causes the Chevy Spark Heater Not Working?

Low Coolant

Low coolant causes the car to overheat, which in turn causes the heater to not work. You should have at least a full gallon of coolant in the car when it is parked. If you don’t, then it could cause you to have a breakdown.

An overheating car is a very dangerous thing to have, especially if you are driving down the road. This can cause you to have a severe accident or even a fire. You should have the coolant replaced immediately if you notice that it is low.

Heater Fluid Leak

The heater fluid in the Chevy Spark is a type of antifreeze. It protects the engine from freezing, which is why it is there. If the fluid leaks, then you will not be able to turn on your heater, which could lead to an accident.

The fluid needs to be replaced every two years. If it has been more than two years since you replaced it, then you should do so as soon as possible.

Dirty Air Filter

If your air filter is dirty, then it will be unable to breathe properly and could cause your heater not to work properly as well.

A dirty air filter will not let your heater breathe properly and could cause damage to the engine and possibly an accident if you are driving down the road at high speeds or on a highway at night time in bad weather conditions.

You need to have this air filter cleaned out as soon as possible so that you can have proper breathing while driving your car in inclement weather conditions. This can be done by a professional mechanic if you are not familiar with doing this yourself.

Bad Thermostat

The thermostat is the part of the heater that controls how much heat the car can produce. If it is faulty, then it could be not working properly. The thermostat could be worn out, which will cause the car to overheat, which in turn could cause your heater not to work.

If you notice that your thermostat is broken or malfunctioning, then you need to get this fixed immediately by a professional mechanic. You should also get a new one because this part will become faulty after a certain amount of time.
