The source guide covers replacement illuminated speaker covers for Mercedes-Benz C-Class 205, GLC 253 and E-Class 213 vehicles with existing ambient lighting or a retrofitted 64-color ambient-light system. It illustrates two different connection routes. Confirm the vehicle's equipment, cover-light version and harness before installation; do not assume that one pictured door or connector layout applies to every listed model.
1. Components and preparation
Before removing the door trim, identify the left and right covers as shown in Figure 6. Inspect the foam in the replacement trim and keep the internal white foam in place. The source explicitly says it does not need to be removed. Lifting the larger door-panel foam layer to access clips, as shown in Figures 4 and 5, is a separate operation.
The illustrated removal sequence involves electrical connectors. Use the applicable vehicle procedure to make the circuit safe before disconnecting or reconnecting them. The source does not specify power-disconnection details, refitting torque, adhesive selection or complete terminal assignments; confirm those details for the actual vehicle and kit before proceeding.

2. Door-trim removal
2.1 Front door
Read Figure 2 from top to bottom. The source shows T30 screw removal, release of the lower and upper door-panel clips, the outer clip positions, lifting the panel evenly, and disconnection of the interior handle cable and midrange-speaker connector. The last photograph identifies blue connections No. 5 and No. 6 on the illustrated door module. These are connection identifiers in the source, not individual terminal numbers or a universal pinout. Verify the module and harness before disconnecting them.

2.2 Rear door
Figure 3 shows T30 screw removal, release of the lower and upper clips, and disconnection of the interior handle cable and midrange-speaker connector. The final photograph again identifies the illustrated door-module connections as No. 5 and No. 6. Confirm the rear-door arrangement for the actual vehicle; do not transfer the photograph's connection numbers to another module version.

3. Cover replacement
3.1 Front door
Figure 4 shows lifting the larger foam layer, releasing the upper trim's retaining clips and disconnecting the seat-control switch connector. It then shows removing the existing door-panel light unit, removing the adhesive securing the existing speaker cover and replacing the cover. The final photograph shows releasing two speaker mounting points to create a gap for routing the wire.
Figure 4. Front-door cover replacement and wire-routing example. Confirm the method for securing the replacement and refitting the speaker; the photograph provides no tightening or adhesive specification.
3.2 Rear door
Figure 5 shows lifting the larger foam layer and releasing the upper trim's retaining clips, removing the door-panel light unit, removing the existing cover's securing adhesive and replacing the cover. Its final photograph shows releasing two speaker mounting points to route the wire through the resulting gap.

4. Cover orientation, foam and connection route
Check the internal white foam and leave it in place. Use the cover's indicated left/right orientation before refitting the trim.
- Existing ambient lighting: the source shows an adapter at the existing door-module connection identified as No. 6. Confirm that the actual module and adapter match the illustrated version. No. 6 is not an instruction to insert a wire into terminal 6.
- Retrofitted 64-color ambient lighting: the source shows the cover connecting to the added lighting module, using the harness supplied for that system. Do not substitute the existing-lighting connection route or guess the added module's terminal arrangement.

If the module, adapter or lighting system differs from the example, obtain the correct instructions before connecting. Restore all disturbed connectors, cables, speakers, foam and trim using the verified vehicle/kit procedure, then check operation.
5. Troubleshooting
Make the circuit safe before removing or substituting components. The checks below describe the source's fault-isolation suggestions; a single result does not establish a confirmed diagnosis.
5.1 Vehicles with existing ambient lighting
- Cover light and existing door ambient light are both off: the source suggests a 10-minute locked-vehicle sleep cycle. Restoring the original wiring with the adapter removed can help determine whether the adapter or added wiring is involved. If the original system is still abnormal, investigate it and any other added adapters; do not conclude that the original signal is faulty from this check alone.
- Existing door ambient light works but the cover light is off: inspect loose connectors, bent or deformed terminals and mismatched wire/terminal positions. A confirmed matching, known-good adapter can help isolate an adapter problem. If the symptom remains, inspect the light unit and its connections before assigning a cause.
- Multicolor operation does not match, but single colors work: compare the cover-light identifiers. The source specifies 16 for E213, 17 for C205 and 18 for GLC253. These are light-unit identifiers for the illustrated product, not model years or terminal numbers. Confirm the appropriate replacement version if the identifier does not match. Figure 7 shows the identification location.

5.2 Vehicles with retrofitted 64-color ambient lighting
- All ambient lights and cover lights are off: check whether the added ambient-light system itself operates normally.
- One door's added ambient light works, but its cover light is off: inspect loose adapters and bent or deformed adapter terminals. A verified matching, known-good light unit can help isolate a light-unit problem.
- One door's cover light and ambient light are both off: inspect the added module's connectors and check whether that module operates normally.
- A mixed color is abnormal: check red, green and blue individually in the single-color controls. If a color is absent, inspect the light unit and wire/terminal alignment. If all three are present, the source suggests checking whether the added system needs color synchronization. It does not provide that procedure; obtain the instructions for the exact lighting system rather than inventing a synchronization sequence.
For support, provide the vehicle model/year, existing or retrofitted ambient-light system, cover-light identifier and the affected door, figure or step.
