In your Volkswagen, a wiring harness is basically an assembly of cables in which wires that transmit the electrical energy of the car are housed. These wires are necessary because they will transmit all of the electrical power to all of the different components in the car.
The wiring harness in your Volkswagen is designed to last a long time. No one wants their car to stop receiving electricity since it is necessary for almost every system of your vehicle. However, the wiring harness in a VW is known to malfunction from time to time, so it’s prudent for VW owners to know the signs of this type of failure.
Volkswagen owners must first recognize the purpose of the wiring harness. This housing is important for protecting the wires of the car, preventing exposure to the outside elements and to unnecessary friction.
When these wires become exposed, they are a big accident waiting to happen. Exposed wires can interfere with how well they transmit information to sensors that alert the onboard computer to all sorts of important data and commands. If wiring interference or degradation occurs for long enough, the wiring may cause certain systems in your Volkswagen to fail and it could leave you stranded.
When the wiring harness is in place, all the wires stay protected by its housing. The wiring harness will need replacing over time, but it can usually do its job for a long time. While protecting the wires, the wiring harness can also significantly reduce the chances of accidental fires in the vehicle.
The wiring harness will be affected by normal wear and tear after being in use for a long time. This wear will often show up in the form of the harness being stiff. While the wiring harness may still perform its job and be in good shape, it may get softer and bend easier. This makes breakage less likely. When the harness stiffens, it is easy to break.
External factors often cause the wiring harness to stiffen. Extreme weather conditions may cause the rubber material to contract and expand, affecting the flexibility of the product. One hot day is not enough to cause damage, but over the years, this constant shift in temperatures can ruin the wiring harness and eventually make it crumble and expose the sensitive wiring.
VW owners can look for some of the common signs of wiring harness failure. The first sign that you may notice is that the car will not start when you turn the key in the ignition. When the wiring harness is not able to send an electrical current to the fuel, the necessary spark and ignition sequence will fail, and your VW won’t start.
Another indicator that the wiring harness does not work is flickering or dimming lights within the cabin of your car or of the headlights, fog lights, blinders, and taillights. Often the rear and front lights rely on the power of the car battery. When there is a problem with the wiring, the lighting will be inconsistent and may make driving at night difficult.
Failure to fix the wiring harness may result in the front and rear lights not turning on at all and making it impossible to drive in bad weather or at night.
A damaged wiring harness makes it dangerous to drive. Your lights may not work properly and there is the potential of a fire in your car.
