Body grille in the rear and rear ventilation flaps serve the so-called forced ventilation. Visible visually, they are mainly found on vans, but occasionally on other vehicles. In most cases, they are already in series where they are needed. However, a replacement of a rear ventilation may be required if it is defective. Additional built-in rear ventilation is used to transport animals in case of odors or moisture in the rear.
The forced ventilation
Forced ventilation is any type of ventilation that is outside the control of the vehicle occupants. So you can not turn the air flow from the rear ventilation on or off. The reason for this is that it serves to remove moisture and exhaust fumes that penetrate into the rear of your vehicle. A shutdown would result in accumulation of moisture or toxic gases in the cargo compartment of your car. In this area, there are no people on the move who could be bothered or damaged by the draft. Only a few car models, you will also see the side of the rear window grid, for forced ventilation of the interior, find.
From a mechanical blockade, or the expansion and closure of a standard installed forced ventilation is strongly discouraged.
Even if it is only a trunk or the loading area of a transporter, forced ventilation is not built in without reason or as a pure decoration. The exhaust gases not only damage your health during loading and unloading, but can also damage the cargo. In places where moisture accumulates, it quickly molds. Molds often release poisonous spores into the air and can also spread to the cargo. In addition, there is the risk of moisture damage to moisture-sensitive cargo. Furthermore, it also serves to equalize the pressure. If, for example, the tailgate is closed, the compressed air created by closing can escape through forced ventilation / forced ventilation.
Body mesh or fan in the rear area
It is especially important to install or replace a forced ventilation of the rear if you notice that exhaust fumes or moisture collect in the rear of the vehicle. The first you recognize very easily the smell. However, the accumulation of moisture can go unnoticed for a long time. You recognize them by the formation of wet spots that can not be explained by the ingress of rainwater during the loading activity and also do not dry up quickly. If it remains unrecognized, it comes to the formation of mold or in the course even rusting. First, check if an existing vent is blocked or broken or if there is a leak in the vehicle. Caulking or removing the blockage may be the better solution. However, a defective fan must be replaced. Another reason for installing a ventilation may be the transportation of animals in the rear. Especially large dogs are often better accommodated there than in the back seat. However, you need enough fresh, not exhaust-laden breathing air. The replacement of the ventilation can, with a little manual skill, usually be done by yourself.
But make sure that you buy the right spare part for your car and assemble it well, so that it does not come loose during the ride. If you want to install a completely new rear ventilation, you should have that done by the professionals in your workshop.
