Why can't the power sliding door of the GL8ES open automatically?
2 Answers
The reasons why the power sliding door of the GL8ES cannot open automatically: the controller malfunctions, and the switch fails. Below is the relevant introduction of Buick: 1. Configuration: Equipped with an ultra-luxury audio-visual playback system that can play CDs, VCDs, and MP3s, an advanced intelligent driving assistance system, an FDM high-definition streaming media rearview mirror, a cruise control system, a third-row flat-folding seat, dark UV-resistant glass, and many other high-end configurations; 2. Powertrain: The new generation GL8-ES is equipped with a 2.0T variable cylinder turbocharged engine, featuring Tripower variable valve management technology, intelligently and smoothly switching between "four-cylinder high-performance mode," "four-cylinder economy mode," and "two-cylinder ultra-economy mode," paired with a 9-speed HYDRA-MATIC intelligent transmission.
Last month when I was driving my brother's GL8 ES, I encountered this issue too. Later I realized it was actually due to incorrect operation method. For this type of power sliding door, you need to first unlock the vehicle, then wait for the indicator light near the door handle to illuminate before sensing with your hand. Another common situation is trying to open the door before the vehicle comes to a complete stop, or having the door track jammed by mud and sand. In my case, I cleared the pebbles from the track groove and it worked fine. Also check if the automatic door opening function was accidentally turned off in the central control settings. If you've recently installed dark window tint, it might interfere with the sensors - it's best to visit the 4S shop to adjust the sensitivity.
