How a heater works on a jeep wrangler

When it is cold, heating is our best ally on the road to go to work. And when the latter is no longer activated we notice it ardently. Therefore before finding out what the problem came from, it is necessary to understand how it works on this jeep wrangler, at least its principle. The heating uses the engine block temperature to warm the personalised tour, then in most cases the cooling system. So it's a two in one. Also, the emission system, so that the hot air comes into the cabin has a double system. There is a ventilateur which emits hot air when the car is driving slowly or is stopped, then it is the speed of your automobile which allows hot air to be sent when you are traveling at high speed. It's pretty clever isn't it?

Recurring heating problems on a jeep wrangler

Broken thermostat

The concept is easy, if the thermostat which regulates the temperature does not really understand the temperature of the water circuit, the entire circuit is affected. Even if the thermostat of this jeep wrangler does not work properly, the heating will still work. Because the natural temperature of the engine block will increase over time, so the water circuit at the same time, whether the thermostat works or not. Our only annoyance is that you will have trouble adjusting the temperature.

Air flaps blocked on the jeep wrangler

This is a problem that happens quite often. These shutters, which allow you to direct the air or adjust the intensity, sometimes get blocked over time. To remedy this it is simple, remove the cover and look inside how it was done. Activate the mechanisms to see where it is blocking. Put a little WD 40 to lubricate and voila.

Defective fan on the jeep wrangler

As you will understand, the fan is useful only at low speed and the engine off. If your heating does not generate too much air at low speed and you nevertheless hear a sound, it means that the fan is probably faulty. If all goes well, with a high speed the heating of this jeep wrangler will work. If it happens that the fan does not work at all it will have to be changed.

Blocked hoses

Its signs turn out to be relatively obvious. If your heating works and does not create heat or very slightly, the problem probably comes from the hoses. They become blocked over time and no longer allow hot water to access the heating of this jeep wrangler. So, clean the hoses or install new ones.

Air pocket in the jeep wrangler circuit

The symptom will be identical to that of the hoses. If ever air pockets are inserted in the heart of the circuit, hot water also has problems accessing the heating radiator of this jeep wrangler. Then, all you have to do is purge the water circuit.

Conclusion

You now know what could be causing the problem. On the other hand it may be that the problem comes from another place, for example the air duct of this cluttered jeep wrangler, even a defective tap, however it is still rather rare. You can write a comment in case this post helped you. See you soon !
