What Causes the Intermittent Failure of the Light Combination Switch in Haval H6?
2 Answers
Haval H6's light combination switch sometimes works and sometimes doesn't due to poor circuit contact. Below are the specific details about the Haval H6: 1. Vehicle Positioning: The Haval H6 is positioned as a compact SUV, available in Blue Label and Red Label versions. 2. Powertrain: It is equipped with two engines: a 1.5T and a 2.0T. The 1.5T engine has a maximum power of 124kW and a peak torque of 285Nm; the 2.0T engine has a maximum power of 145kW and a peak torque of 355Nm. 3. CVVL Technology: The 1.5T engine features CVVL technology. CVVL technology primarily allows for adjusting the timing of valve opening and closing, valve lift, and duration, ensuring that the engine can obtain sufficient air intake under different operating conditions, thereby improving the engine's efficiency.
I've been driving my Haval H6 for over three years and have also encountered the intermittent issue with the light combination switch. To be honest, it's quite annoying. The most likely cause is oxidation or dirt buildup inside the switch contacts. Frequent use allows dust to get in, leading to unstable contact, especially in humid weather. Another possibility is loose wiring connections; excessive vibration can loosen or corrode the connections, causing unstable power supply. I recommend first checking and cleaning the switch, using alcohol swabs to clean the contacts. If that doesn’t work, replace the switch. Additionally, aging circuit boards can cause intermittent faults, which is related to the Haval H6's design. I’ve heard some batches have quality issues, so keeping an eye on it during regular maintenance can help prevent problems. In short, don’t take it lightly—sudden failure while driving at night is dangerous. Get it fixed promptly to avoid turning a minor issue into a major one.
