Especially now, in the colder season, the functionality of the heating fan is very important. And of course, mainly because thanks to it, we can not only heat the interior of the car to the required temperature, but it also happens that the windshield is also defoggered quite simply, quickly and easily. If the heating fan is not working as it should, this is logically a problem. Therefore, let's see how to proceed in the case of a specific exchange, if it is necessary.
The type of car plays a role
We must not forget that the type of your car plays a key role in the given direction. It is logically important to find out in which specific place the heating fan is stored and in which specific way you will be able to get to it. If you are interested in information about where to find specific facts, it must be said that it is ideal to use a service manual for example, which in this regard is the ideal route that will suit you. In the same way, the necessary information can also be found online in a fairly simple way.
If we look at specific cars, it must be said that a large number of cars had and have a fan located in the area under the dashboard, in the passenger compartment. It is here that we recommend looking for it first, as it is very likely that this is the specific place where you will also be able to find it exactly.
Start by disconnecting the fuse
Now we can go down a specific path, which involves dismantling the existing fan. If you follow our specific advice, it must be said that the first thing to do is definitely the duty of disconnecting the relevant fuse. That is, one that is connected to the fan as such. Once the particular fuse is disconnected, you can get down to the next job. Naturally, the reason for disconnecting this fuse is to ensure that the fan is not energized, so you don't have to worry about it possibly starting. Of course, there is also an alternative procedure, which is connected to the fact that you will be able to disconnect the car battery. If this procedure is easier for you, you can.
Begin disassembly
If the heater fan is located in the mentioned space in front of the passenger, it is ideal to proceed with the disassembly by first removing the lower cover under the dashboard, just as it is ideal to also remove the passenger compartment. Of course, don't forget that it depends on the specific type of your car. The disassembly procedure should be the same for most of them. And such that you first find the individual screws, which you gradually dismantle. As soon as all the screws are removed, it should happen that you can release the specific compartment, as well as the cover itself under the dashboard, in a fairly simple way. Once that happens, you should have pretty good access to the fan in question. Thus, the initial procedure associated with disassembly is over.
Disassemble the fan itself
Once you have much-needed access to the fan, you can start disassembling it. Don't forget one important thing here, naturally, that the given fan will be part of the block of the heater itself. And that in this case means that you also have to dismantle it from it. However, it does not have to be a big and unsolvable problem for a whole range of cars. Naturally, this is due to the fact that the fan itself just needs to be turned, thanks to which you will be able to easily release it. This is also one of the reasons why we recommended having more space for subsequent work during the initial disassembly.
Also, once the fan itself is enabled, don't forget that it is still attached to your car. And so it must first be disconnected and only then comes the most important step, when you carefully remove it from the car, sometimes with a little force. Once removed, it can be tested.
Since the primary goal is to replace the heater fan, it is ideal to first determine if the current one is actually faulty. You can find out quite simply by connecting it to the source. Here, pay attention to the fact that it should only be a source that has a voltage of 12V. Once you plug it in, either nothing happens or it spins. If there's one thing we definitely recommend, it's to be careful and protect your fingers, because any spinning will happen very quickly indeed. Safety should be the first priority in any given procedure. If it spins, it is more than clear that the specific problem is somewhere in the connection itself to your car. Here it is already a good idea to contact an auto electrician, who may not only have the necessary equipment, but may also have the necessary experience.
Fan replacement
If you really find that the current fan is not working, it is clear that you cannot do without a replacement. You can buy another either new or used. Do not forget that it should be the type designed for your car. Once you have it, proceed in reverse to assemble it. We recommend testing it first before placing it in the car. Of course, first you need to connect it, and only then focus on its proper seating in place.
Once it's in place, it's a good idea to first plug in the fuse and classically test if everything really works the way it's supposed to. If so, it is a good idea to turn off the fuse again for your greater safety and then install your dashboard covers in the classic way. Once done, the fuse can be put back in place. At this point it will also happen that the heater fan replacement should be fully done and it should be working as well as you want it to again.
