Interior button releases but does not close. I can pull it to open, but it does not push (to close). The trunk mounted buttons open/close fine. My question: Is the interior button designed to push? Or do you have to pull it aain to activate the closing sequence. I can't push it so I'm guessing that it needs replacement. The vehicle is new to me. The manual states that I have to push it

Per the first illustration, the button is for opening only. Quite disappointed this closing feature was not included in this year of AMG (WDDDJ77X87A084699) Can you confirm for me using the vehicle number?

Thanks

According to data card this VIN should be equipped with optional remote trunk closing code 881 view marketing brochure here: http://www.auto-brochures.com/mercedes_benz.html perhaps a discussion with whomever you purchased from is in order.

Good info. Do you think changing the button to a two-way type will work. The current button may have been a replacement part done error before I purchased the car. Otherwise I plan to pin-out the connector to see if it will activate the closing. At this point I'm assuming that the number of pins in the connector are the same for both versions of operation.
Thank you

Bought a used switch in preparation for this job. Upon removal of the original trunk switch I found it to be clogged with a hard brown material (food?). Cleaned it out and blew it with compressed air. It now opens/closes the trunk perfectly. Now onto replacing the rear shade (won't go down). Been trying to find a thread on the topic. Can you redirect me?

Hey other members,,,,,, I have a used trunk switch for sale. You just pay the shipping😊.

Thank you for your guidance Konigstiger!

Check f20 @ rear SAM (behind left trunk panel).

Try this. With the assistance of another person, apply gentle pressure to the scissor arms towards the center of the main cross bar. At the same time guide the main cross bar down. As the entire unit starts to collapse, it should go back inside fairly easily.

Bad motor, MB only offers roller blind assembly part # 2198100020 if replacement needed.

Konigstiger:
Quite a learning curve taking out the rear shelf. Spent about 40 minute figuring out how to "operate" the rear headrest release levers. After that, the other took 1 minute. Same issues with "raising the read shelf" to remove various items. I did take the time to paint the faded shelf and speaker screen back to flat black. No one will know but me

Well, I got the shade removed only to find that it worked ok when supplying independent 12V power. Checking the wiring found 12V, after a brief delay, when pushing the dash switch. Is this delay normal? Had to sometimes push the switch multiple times to get it to provide the 12V. BUT..... the shade does not move up/down. This applies to both the original and used shade I purchased.

Where do you think the problem is? The switch or maybe the relay? I don't think the switch is available separately (only as part of the lower dash switch assembly?)

Your thoughts?

Checked the wiring runs and all appears OK. I also reset the grounding post wires. I did not check the dash control panel connector (the panel that contains the seat heater/hazard flasher/sunroof /etc).

At the K74 module I noted that the brn-wht wire has a constant 12v, no matter if I pushed the dash switch. I would think that it would switch 12v power to either the red-wht or the brn-wht wire each time it is pushed (correct?). I eventually replace the K74 module,.... to no avail..

So now I believe that the dash switch needs replacing (your thoughts?). When shopping for used parts I note that the color of the wood trim surround does not match mine. Can the wood trim be transferred over the the used part? also, can the switch be replaced seperately or do I have to buy the whole assembly?

Switch block (2118218858) can be transferred to your wood surround. MB does not offer buttons separately but here’s the reverse side of block, attempt to open and swap switch. I never attempted this. Before purchasing, check switch block may be contaminated like door switch was.

Used part did not solve the problem. Going back to pin-out procedure to recheck circuits.

Konigstiger,
There are two unconnected yellow wires with connectors at the back of the CD player assembly that I can't figure out where they go. I assume because of the yellow color they are related to the security system. Can you provide the circuit diagram for this?
