How a heater works on a Jeep Wagoneer

In winter, heating is essential on the way to work. And when the latter no longer works, we quickly miss it. So to understand what is causing the malfunction, it is necessary to know how it works on your Jeep Wagoneer, at least its principle. The heating uses the temperature of the engine block to be able to raise the temperature of the personalised tour, then in most of the cases of the cooling device. So there is duplication. Similarly, the fan device, so that the air reaches us also has a double use. There is a ventilateur which sends the air when the car is running at low speed or is stopped, then it is the speed of the car which makes it possible to send the air when you are driving faster. It's pretty clever isn't it?

Recurring heating problems on a Jeep Wagoneer

Broken thermostat

The notion is easy, assuming that the thermostat that regulates the temperature does not really measure the degree of heat of the water in the circuit, the latter is affected. Even if your Jeep Wagoneer's thermostat no longer works properly, the heater will still work. Quite simply because the temperature coming from the engine block will gradually increase, then the water circuit too, even without a thermostat. Our only concern is that you cannot really change the temperature.

Air flaps blocked on the Jeep Wagoneer

It is a dysfunction 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.

Faulty fan on Jeep Wagoneer

As you can imagine, the fan is effective only at reduced speed and stopped. If it happens that the heating does not send air at reduced speed but that you still discern a sound, it is good that the fan is probably defective. If all goes well, thanks to more speed the heating of your Jeep Wagoneer will work. If it turns out that the fan really does not rotate it is better to change it.

Blocked hoses

Its signs are fairly obvious. In the event that your heating works but does not heat or very little, the malfunction certainly comes from the hoses. These become blocked over time and no longer allow hot water to reach the heating of your Jeep Wagoneer. In this case, wash the hoses or replace them with new ones.

Air pocket in the Jeep Wagoneer circuit

The symptom is the same as those of the hoses. If it happens that air pockets are inserted within the circuit, the high temperature water also has problems reaching the heating radiator of this famous Jeep Wagoneer. In this specific case, it will suffice to purge the water circuit.

Conclusion

You now know what could cause this malfunction. On the other hand it is possible that the problem comes from another place, for example the air duct of your obstructed Jeep Wagoneer, or a defective tap, but this remains unfortunately more rare.
