Mercedes Benz recalled many vehicles manufactured between 2001-2011 for potential sunroof issues. However, the recent Mercedez car has a robust sunroof and is less problematic.
But it’s a piece of equipment that ends up being a liability, and you need to spend the hard-earned money on its repair many times.
So, if your Mercedes sunroof isn’t working read on to learn how to fix this problem.
How Do You Reprogram A Mercedes Sunroof?
Most of the time, a simple trick works like magic. So before diving deep, you must try to re-synchronise the sunroof.
- First, lock the car doors and access the forward button of the sunroof attached to the roof. Do not leave until it closes all the way. Hold the switch for five seconds.
- Now press the tilt switch and hold it for five seconds.
- Afterwards, press the open switch, which will begin sliding backwards slowly. Hold the open switch for an additional five seconds.
- Once more, close the sunroof by pressing the forward button and holding it for five seconds. That should reset the Mercedes sunroof.
- Check If the Mercedes sunroof opens with one touch of the button.
If not, then read the next section to troubleshoot the sunroof problem.
Pro Tip: If the sunroof does not close, try disconnecting the battery for at least ten minutes. The battery disconnection will reset the operating system.
Why Mercedes Sunroof Won’t Close All The Way
1. Misaligned Sunroof
The Mercedes sunroof can get tilted on one side. The misalignment is a significant hindrance in smooth movement on the sunroof rail track.
Over time the guides on the rail track break or the plastic pieces over the sides move from their place or get broken. In either case, the sunroof would tilt on a side or rise from a side and refuse to move.
In either case, it would be hard to reposition the sunroof glass on its track. It would be best to look for breakage in the track as a solution.
If so, you must replace the whole track to fix the Mercedes sunroof.
2. Mechanický problém
The sunroof track in Mercedes may have broken wire, a plastic piece, hinges broken from the rail track, or a nail that stops the sunroof from moving ahead.
The motor and all the other electricals are fully functional, but you need to do a detailed visual inspection for potential mechanical problems.
Thoroughly check for dust, debris, stone, wire, or anything that’s getting in the way of the sunroof.
4. Špatná pojistka
Mercedes’ sunroof motor has an attached fuse that prevents extreme overload in adverse situations.
If your Mercedes Sunroof won’t close all the way, checking the fuse should be the first step before applying any hack.
Using a multimeter, you can DIY-check the fuse and replace it if it’s bad.
5. Rusted Sunroof Track
The Mercedes rail track is prone to rusting if it’s not cleaned for a long time. The rusted track would prevent the smooth sliding of sunroof glass on it, and eventually, it will stop working.
Hence it’s best to periodically clean it like the rest of the car parts and remove the rust with the help of a WD-40 solution.

Vyrostl jsem v malém městě v Novém Mexiku a tam začala moje láska k vozidlům. Tam, kde jsem bydlel, nebyly žádné zpevněné cesty, takže jsme museli jezdit po prašných stezkách, abychom se tam dostali. V dnešní době mě stále baví co nejčastěji vyrážet do přírody. Ale teď s sebou beru i přátele, kteří také rádi tráví čas venku na motorkách a terénních vozidlech.
