What to do if the headlight height of Trumpchi GA6 cannot be adjusted?
3 Answers
If the headlight height of Trumpchi GA6 cannot be adjusted, it may be due to rust on the fixing screws. Here are the steps to adjust the headlight height of Trumpchi GA6: 1. Find a wall and park the car 10 meters away from the wall; 2. Measure the height from the ground to the center of the headlight and the distance between the two headlights; 3. Place a horizontal masking tape on the wall 0.1 meters lower than the headlight height, ensuring the tape is at the exact center of the car; 4. Turn on the headlights and adjust the vertical adjustment screw until the headlight beam is centered on the tape on the wall; 5. Continue adjusting the vertical adjustment screw until the headlight beam is pointing straight forward.
I've driven a Trumpchi for ten years, and the GA6's headlight height adjustment issue really requires opening it up. The most straightforward cause is the height adjustment knob inside the car being stuck—give it a few hard turns to see. If it clicks but doesn't move, chances are the internal adjustment module is broken. Alternatively, pop the hood and crouch near the left front wheel to feel behind the headlight. There's a small white square motor connected by a wire—that's the key to height adjustment. If you hear an odd buzzing sound, the motor might still be working but the gears could be slipping. Replacing this part isn't expensive; you can get the whole assembly for around 200 RMB on Taobao. But be careful if you've retrofitted HID lights—I once messed up the wiring harness and blew the fuse three times, which was a nightmare. I recommend checking the No. 25 fuse under the steering wheel first. It's located in the panel above the driver's knees—use small tweezers to pull it out and see if the filament is broken.
A friendly reminder from the auto repair shop: Last week, we fixed the same headlight height adjustment issue on a GA6. Focus on three key areas: First, check the square box next to the battery in the front. Lift the black cover to reveal the headlight height adjustment module—the connector is prone to water splashes and rust, which can cause malfunction. Second, ensure the small knob near the driver’s left leg is turned all the way down. Some people accidentally block its movement when installing floor mats. Third, use a flashlight to inspect the inner wheel well near the mudguard. Many cars accumulate debris after driving through puddles, blocking the motor’s cooling vents, which can lead to motor failure due to overheating. A word of advice: Don’t force it. Driving at night with improperly adjusted headlights is extremely dangerous. If this happens, turn on your hazard lights immediately and use a flathead screwdriver to manually adjust the gear screw behind the headlight under the hood—you can see the beam height change in the rearview mirror. Get it repaired first thing tomorrow morning.
