The Chinese source identifies model-year 2020–2024 Mercedes-Benz GLE167 / GLS167, and the pictured installation sequence is headed GLE. It describes a lighting adapter, but provides no kit part number or option-specific compatibility evidence. Confirm the cover and adapter for the actual vehicle; this guide does not establish universal fitment, a no-cut installation guarantee or an audio-performance improvement.
Connector reference: “No. 6” below is the blue module connector described by this source. It is not an instruction to use pin 6. The photographs provide no pinout or wire-function legend; confirm the actual module/adapter combination before connecting it.
GLE installation sequence shown in the source
- Use a trim tool to remove the trim cover at the door-panel handle.
- Use the T30 tool specified in the source to remove the two door-handle screws indicated by the arrows in the photograph. The source supplies no reassembly torque.
- Use a trim tool to remove the factory cover at the door's A-pillar position.
- Route the ambient-light unit wire through the speaker gap and secure the light unit to the cover's light guide.
- Connect the illuminated-cover adapter to blue connector No. 6 on the factory module.
- Clip the illuminated cover back into position and refit the door trim to complete installation.
Troubleshooting references requiring product confirmation
Source inconsistency: the title and installation steps identify tweeter covers, but both troubleshooting entries explicitly refer to illuminated midrange covers. Their applicability to this tweeter-cover kit has not been confirmed. Obtain the correct kit troubleshooting instructions before using the checks below; they are retained as source references, not as confirmed fault diagnosis for the tweeter covers.
-
None of the vehicle's illuminated midrange covers illuminate: check whether the factory door-panel ambient lights are also off, and lock the vehicle and let it sleep for 10 minutes. The source also calls for ambient-light unit bus addressing/learning, but gives no tool, menu or procedure. Check that adapter connector No. 6 is secure. Restore factory connector No. 6 and check whether factory ambient lighting operates normally.
-
One illuminated midrange cover does not illuminate: substitute a working No. 6 adapter and check whether the light illuminates. The source associates a successful substitution with an adapter fault and calls for a comparison of the adapter pins; otherwise it attributes the problem to the light unit. These conclusions have not been verified for the tweeter-cover kit and should not be treated as a conclusive diagnosis.
