my car heater fan is not working

Your vehicle works with a radiator that eliminates heat from the engine giving a smooth and calm ride without damaging the parts. It causes the coolant to freeze over time quickly.

Those are also relatively easily to replace on your car with simple tools and a little research.

. The heater core gathers the heat in the system and pushes it inside the cabin in hot air when heating. Most cars should have a fan behind the condenser and it should immediately turn on when you turn on the AC. Other possibility and very common also is the cabin heater regulator they ofetn go located in the middle of the car looking into the engine compartment has 2 pipes one in one out feel the pipes see which is hot etc and get back to me.

Just as your engine needs enough gasoline to run your heating system is the same with coolant. A problem with the switch which turns the fan on or off might also be the source of the problem. The fan inside your car then blows heat off of it to give the cabin heat.

The pollution in the vehicles conditioning system is one cause why your car heater is not working. One of the main reasons your car heater isnt working is leakage in the radiator. In the case of the latter cleaning it with a coil cleaner will be sufficient.

Broken Wiring or Bad connection. If it doesnt turn on then the condenser wont work optimally. The leakage in the radiator drains the water causing damage to the engine.

The coolant level should be at the top of the radiator neck. According to the Popular Mechanics website a common cause of a cars heater not working is a buildup in the heater core. Using a 5050 mix of anti-freeze and distilled water top off the radiator and fill the coolant reservoir tank to the.

Check for blown fuses and replace them to restore normal functionality. To determine if this is the problem when the engine is cool remove the radiator cap. Coolant System Your engines cooling system works in part by the coolant traveling through a heater core that heats the inside of your car.

The radiator cools down the heated parts and gives. There are some very thin tubes in the heater matrix and if it becomes blocked the coolant may. It generates the motor heat that stops the heater from functioning.

If the thermostat is jammed open causing the car to overcool there may not be sufficient temperature in the coolant to provide sufficient hot air. Final Thoughts On My Car Heater Is Not Working The good news is that if you have a newer car problems with the heating system are rare. Hi its ounds like the fan has failed the fan blows the heat into the vents without it it will just remain in the heater core.

The coolant needs to be flushed and replaced. Get a new resistor here. Test or replace the thermostat as mentioned above if you suspect this to be the cause.

The heater fan is responsible for dispersing the air throughout the cabin. The heater fan is responsible for dispersing the air throughout the cabin. Grime or other sediment accumulate in the core and restrict the flow of heated coolant that serves as the source for the heater.

Without the heater core your car cannot heat up. Check the wirings going to the radiator fan from the control unit or relay. If your fan stops blowing on one speed but works on another then you have a bad blower motor resistor.

All power to every one of the electrical working parts of the car is supplied via fuses. If the fan is not working even when the car is overheating there might be a wiring issue or a bad connection. A damaged radiator can leak and prevent coolant from reaching the heater core.

Even if every other part of your cars heating system works properly you wont feel any warm air if the fan doesnt work. Here are some things that could be causing your heat not to work. Thanks again for your question.

The heater fan is also sometimes an issue. Low coolant level is the most common cause of poor heater output. Basically its a small radiator that hot coolant flows through.

A blown fuse might just be the reason your car heater fan is not working.
