What is the reason why only one speaker in the Envision has sound?
3 Answers
Envision speaker only has sound in one side due to: 1. Circuit failure; 2. Other speakers getting wet. The Envision is a mid-size SUV under the Buick brand, equipped with two engines: one is a 1.5-liter turbocharged engine with a maximum power of 124 kW and a maximum torque of 250 Nm; the other is a 2.0-liter turbocharged engine with a maximum power of 191 kW and a maximum torque of 400 Nm. The front suspension of the Envision uses a MacPherson independent suspension, and the rear suspension uses a multi-link independent suspension.
I've driven quite a few cars and encountered the audio issue with the Envision several times. If only one side is working, the main reasons are usually a faulty speaker unit or loose wiring connections. For example, a broken voice coil in the left rear door speaker or an unsecured connector in the right front door. Another common factor is a blown fuse—check the audio-labeled fuse in the engine compartment's fuse box. Misconfigurations, like an overly adjusted left-right balance in the audio system, can also cause this. For troubleshooting, first try a soft reset of the infotainment system or adjust the balance settings. If that doesn’t work, you’ll need to remove the interior trim to replace the speaker or repair the wiring. Audio issues don’t affect engine safety but can dampen the driving mood, especially on long highway trips where good music matters. Regular maintenance, like dust removal to prevent oxidation, can reduce sudden failures. Avoid DIY electrical tinkering to prevent worsening the issue—leave it to professionals for peace of mind.
As a car enthusiast, I'm quite familiar with electronic systems. The issue of one side of the Envision's audio system being silent often stems from settings problems or loose connectors. Try adjusting the balance back to the center point in the entertainment interface. On the hardware side, it could be due to amplifier channel failure or vibration-damaged cables. I've also encountered cases caused by voltage fluctuations - an unstable alternator can cause speakers to burn out quickly. The diagnostic process is simple: power on and test different audio sources to check for consistency and rule out settings issues. You can carefully check connectors behind interior panels yourself, but leaving it to professionals is safest. While music enhances driving pleasure, avoid excessive volume to prevent hardware damage. Preventive maintenance includes regular cabin cleaning to reduce moisture damage to wiring, ensuring more enjoyable journeys.
