As the leaves start to change color and the temperatures begin to drop, the one thing you don’t want to face is a broken car heater. A long commute in the cold winter months without a working heater can be a miserable experience. But before you panic and go spend hundreds of dollars on repairs, try these five fixes for a broken car heater:

1. Check your coolant level:

A low coolant level can be the cause of a broken car heater. The coolant circulates through the engine and the heater core, which then warms up the inside of the car. If the coolant is low, the heater core won’t be able to warm up effectively. So, check the coolant level and refill it if necessary.

2. Check the thermostat:

A faulty thermostat can also cause heating problems. The thermostat regulates the flow of coolant to the engine and the heater core. If it’s stuck open or closed, the coolant won’t flow easily through the heater core, and the heater won’t work. You can test the thermostat by running the engine and watching the temperature gauge. If the temperature seems to be fluctuating, the thermostat may need to be replaced.

3. Check the heater control valve:

The heater control valve controls the flow of hot coolant into the heater core. If it gets stuck or clogged, the heater won’t work. You can check the heater control valve by locating it on the engine and testing it with a multimeter. If it’s not working, it will need to be replaced.

4. Check the blower motor:

If the heater is blowing air but it’s not warm, it could be a problem with the blower motor. The blower motor circulates the air through the heater core and into the cabin. If it’s not working, no air will be blown through the heater core, and the heater won’t work. You can test the blower motor by checking the fuse or using a multimeter. If it’s not working, it will need to be replaced.

5. Check the heater core:

If none of the above fixes work, it could be a problem with the heater core. The heater core is a small radiator that warms up the air before it’s blown into the cabin. If the heater core is clogged or leaking, the air won’t be warmed up, and the heater won’t work. You can test the heater core by feeling the hoses connected to it. If they feel cold, the heater core may be clogged or leaking and will need to be replaced.

In conclusion, a broken car heater can be a real headache, but there are several fixes you can try before calling a mechanic. From checking the coolant level to testing the blower motor, these simple DIY fixes can help you get your heater back up and running in no time. However, if none of these fixes work, it’s best to take your car to a professional to diagnose and fix the problem. Stay warm and safe on the road this winter!
