What is the reason for the malfunction of the GAC GM8 power sliding door?

The reasons for the malfunction of the GAC GM8 power sliding door are: 1. Abnormal battery voltage of the remote control; 2. Button failure of the remote control; 3. Loose or broken components of the power sliding door; 4. Issues with the circuit itself, such as poor soldering or missing soldering. The power sliding door switch of the GAC GM8 is located in the control area on the lower left side of the steering wheel. The vehicle is equipped with a passenger-side power sliding door, which can be controlled using the in-car switch to open and close the power sliding door. Taking the 2021 GAC GM8 Lingxiu Series 390T Luxury Edition as an example: it is an MPV launched by GAC Motor, with a length, width, and height of 5089mm, 1884mm, and 1822mm respectively, and a wheelbase of 3000mm. It is equipped with a 2.0T turbocharged engine, with a maximum power of 185kw and a maximum torque of 390nm, matched with an 8-speed automatic transmission.
I've encountered this issue twice – the power sliding door suddenly stopped working, most likely due to dust accumulation jamming the limiter. That time after rain, the door got stuck halfway open, and the mechanic said sand particles had entered the track. It could also be the door control module freezing, just like a smartphone lagging; a full vehicle power reset for ten minutes might revive it. The most troublesome scenario is a burnt-out door lock motor, especially prone to failure with frequent door operations. Just the other day, accompanying a friend for repairs, the mechanic diagnosed it as a faulty door handle sensor using computer diagnostics – replacing a small component fixed it. If problems persist, I recommend visiting a dealership to scan OBD fault codes; avoid DIY disassembly as it may damage wiring. Remember to have them clean leaves and pebbles from seal grooves during maintenance – those can critically jam the tracks.
I've repaired electric door malfunctions on seven GM8 vehicles, categorized into three aspects. The most common mechanical issue is deformation of the bottom rollers or tracks, especially in vehicles frequently opening doors on slopes. Electrical problems mainly involve oxidation of the B-pillar connectors, particularly prone to poor contact after car washes. For electronic control, overly sensitive anti-pinch sensors are a frequent culprit, where excessively thick window tint can trigger false activations. Last week's case was even more peculiar – aftermarket electric running boards installed by the owner caused interference with the door control system. Here's a handy tip: When encountering malfunction, don't panic. Press the interior switch with your left hand while pulling the door handle with your right, and have someone simultaneously press the key fob unlock button. This triple-action approach can release the electronic lockout. For routine maintenance, remember to spray WD-40 silicone lubricant on the rollers every quarter.
