GUIDE Replacing the sunroof shade W204
I couldn’t find any tutorials on removing the sunshade aside from people just saying “remove the whole headliner”. That’s way too much work so I took some time messing with junkyard cars of the same model and figured it out.
This is my first guide, let me know what you think.
1. First thing to do is to tilt the sunroof up. Either by using the button or by manually turning the sunroof motor.
2. Remove the sunroof drip rail. This rail is used to catch water that seeps past the sunroof seals. It’s held on on either side by clipping into each side of the sunroof arms. Simply pinch each side and push out gently. They can snap if you’re not careful. This drip rail is also used to catch the sunshade and drag it open along with the sunroof when you open it, it also keeps the shade from being closed while the sunroof is open. Think of it as a dual purpose locking mechanism
I broke mine the first time from frustration and not knowing what I was doing.
This clips onto the sunroof arm
3. Remove rubber curtains on each side that covers the sunroof arms and components. You can do this by simply peeling them off. Don’t just yank them, they’ll tear if you’re not careful.
4. Open the sunroof and pull the sunshade closed. It should be easy since the drip rail is not catching the sunshade anymore. You should be able to see the top of the sunshade.
5. Remove the sunshade. The trick is to bend the shade upwards so one side releases from the guide rail. Use one hand to push up on the middle of the shade and another on either end to push inwards, helping to bend the shade, and up to get it off the rails.
6. There’s three guides on each side of the shade. Free the first and slide the shade forward, rinse and repeat for the remaining guides. The sunshade should now be free from the guides.
7. If you have a replacement sunshade, do the reverse and reinstall, otherwise fix the damaged one. Trim the ripped fabric and straighten the guides as best you can if they’re all bent up. You can tape the guides with some heavy duty tape to smooth them out and let them slide on the rails easier. Use something better than tape if you want a more durable solution.
8. Reinstalling them is a little trickier. You still want to bend the sunshade to place it back on the rails but you need to be careful as to not damage the guides again. I used a plastic trim tool to help guide them back into place on the rail.The guide rail is shaped like a really long letter “E” the sunshade sits on the very bottom indent of the “E” not the top, if it sits at the top, it’ll collide with the sunroof and the drip rail.
Damaged guides on one side of sunshade
The guides on one side of my sunshade was heavily damaged from the previous owner derailing it. That one side started colliding with the drip rail and all the rubber seals up there and tore it up bad. Eventually the sunshade started catching and would ruin the sunroof motion when opening, causing the motor to click and misalign. This can be fixed by walking the sunroof closed, just tap the button to close it inch by inch. Holding the button down won’t help. You can also pull the sunroof closed while you press the button to help the motor out. When it’s fully closed just hold the button to close the sunroof several times and it will reset itself.
I’ve seen other sunshades from different models that had metal clips as guides on the sunshade, this required lubing to maintain them, I don’t see how this would apply to this car without the lube seeping onto the sunshade fabric so I just did a quick wipe down of the guides.
You should be fine without the drip rail as long as you don't use high pressure to wash your car. I never had a leak from rain or hosing down the car.
