Wiring harness failure is an inconvenience your Volkswagen might eventually develop, and it can be caused by many factors, including age, harsh conditions, and poor maintenance. This issue can manifest through many symptoms, including engine misfires, difficulty shifting gears, stalling, or even failing to start completely.
If you suspect your Volkswagen might have wiring harness issues, the best thing to do is take it to a qualified automotive specialist. At Carotech Automotive in Los Angeles, we specialize in Volkswagen and other European and Japanese cars and can properly diagnose the problem and fix it efficiently. We can also take preventative action by keeping a regular maintenance schedule and regularly inspecting the wiring to avoid this type of problem altogether.
Let’s talk about the wiring harness, how it works, and how to know if it’s failing.
Wiring Harness 101
A wiring harness is a flexible component used to direct current to the components in your car’s electrical system, transmitting signals from the driver to the vehicle and external parts. It is made up of connectors, terminals, wires, covers, sealing components, and labels. Think of the engine as the heart of your car and the wiring harness as the nervous system, connecting all the electrical components in one.
The wiring harness is in charge of carrying electricity from the battery throughout the car’s entire electrical systems and components. It is essential to your Volkswagen’s general functioning, so its failure can be a serious issue that can cause electrical system failures and engine performance issues.
Signs Of Wiring Harness Failure
Over time, your wiring harness can wear out, and they usually become damaged with use, though other environmental factors may also play a part. This can lead to a variety of symptoms that can be hard to detect on their own, but together can indicate a wiring harness issue.
One of the most common wiring harness signs is suffering a sudden loss of power. You might notice a dead battery, dead windows, or your radio shutting off unexpectedly.
Another sign to look out for is how well your engine is performing. If you notice it isn’t accelerating as it used to or it’s consuming more fuel than normal, it’s important to have your car checked as soon as possible.
You might also want to watch out for flickering dashboard lights or a burning smell coming from the engine. This can indicate that the wires in the harness are overheating, most likely due to a short circuit or exposed wiring.
Causes Of Wiring Harness Failure
Wiring harness failure isn’t uncommon in Volkswagen cars, and it can be caused by exposure to heat, vibrations, moisture, corrosion, and poor-quality repair work. This can be prevented by performing regular checks on the wiring harness’s condition to make sure that no exposed wires or tears in the insulation exist.
Why You Shouldn’t Ignore A Failing Wiring Harness
Ignoring wiring harness issues can result in more than just electrical glitches—it can also lead to a complete loss of power, leaving you stranded, or cause components like airbags or ABS systems to malfunction, which is a serious safety risk. Also, intermittent electrical faults can be time-consuming and expensive to diagnose if left unchecked.
