A car is a vehicle that moves on land and is typically powered by an engine. Most cars run on gasoline, but many models are now being manufactured to run on diesel as well as electric batteries.
A car’s heat works by using a heater core which channels hot coolant through tubes throughout the interior of the car. The hot fluid warms the air inside the cabin. Some cars may contain additional heating strips located underneath or behind the front seats to help keep feet warm during winter driving conditions. Many automobile manufacturers also offer optional heated seats for both driver and passenger for added comfort during cold weather driving conditions.
Reasons why would the heat not work in a car
The reason why would the heat not work in a car is because it might not be turned on or it might be broken.
Switched Off
First reason why the heat might not work in a car is because it might not be turned on. In order for the heat to actually work, the switch has to be turned on.
Broken Heater
The second reason why might heat would not work in a car is because it might be broken. If there is some problem with the heater core or if thermostat fails, then there will not be any working supply of hot coolant throughout the vehicle and therefore no heat will escape from inside of a cabin during winter driving conditions.
Fixing Heat Problem in Car
The main switch that controls the heater might not be turned on - There may not be any coolant in the system, so check to make sure there is some before you decide anything else - You can replace or clean out the cabin air filter if that’s what’s causing the heat problems
If those fixes do not work, then it’s probably best just to take your car into a professional service shop as soon as possible. Don’t try to attempt any fixes yourself unless you’re confident that you know how all these different parts of the system work and how to fix them.
When the heater core breaks, it typically means that it has rusted through or cracked somewhere. Replacing this part of the car is not cheap, so you should definitely take your car into a professional shop because there are likely other issues with your car that will be uncovered by examining the heater core.
If your blower motor has fried, then replacing it is much easier than fixing any other problems in this system. This part typically costs very little compared to doing extensive repairs on the rest of your vehicle’s heating and cooling systems. This is why many people recommend just replacing the blower motor first rather than trying to do anything else. The blower motor works easily enough that most people can do it themselves.
If there is no power getting to the heater core, then you will know within a second of turning your car on because there would be no air coming out at all. That’s probably the easiest problem to fix and is also among the cheapest because this job typically only requires checking two or three different fuses in your vehicle.
It can be frustrating when the heat suddenly stops working while you’re driving your car on a cold day, but hopefully, this guide has helped inform people of why their car’s heating system may not be working and what they should try doing about it if they want to attempt to repair it on their own without taking into a professional service center for repairs.
