1994 W140 Sunroof Will Not Close

Hello:

The sunroof of my 1994 W140 stops two inches short of closing, however it opens fully.

I have tried pulling it closed with my hand while pressing the close button, no movement forward.

I have tried the manual procedure in the trunk, no movement forward.

I have tried driving over bumps, railroad tracks, etc. while pressing the close button, no movement forward.

I have searched the forum. Most sunroof issues seem to pertain to the opening of the roof, not its closing. The ones relating to the closing discuss problems with the air deflector not lowering. I do not believe that to be my problem because the sunroof does not get close enough to the deflector for it to lower.

I have also tried holding the deflector down while pressing the close button, still not movement forward.

I hope that I do not need to remove the interior headliner for this repair, as that would be a shame.

Please advise. Your insight is welcomed. Thank you very much.

Most likely some thing is in one of the tracks that guides the lifting angles, disassembly is the only way to find out.

for disassembly will i need to follow the following? the need to remove the headliner of my entire interior would be very unfortunate.

1. Remove the four corner interior pieces and 2 interior pieces between both doors.
2. Remove the rear view mirror, notice mirror is mounted using spring tension, so there is no screws. To reinstall the mirror, sweez the ends of the pins with plier and the tiny pin will hold one side of larg pin back. Then place the mirror back where it belongs and push up with end of screw driver or something similiar.
3. Remove all surrounding pieces around the rear view mirror and sun visors.
4. Remove the 2 back seat ceiling mirrors, they pop into place so you'll have to carefully pry it out. Then there is a screw inside that holds the headliner up, remove that.
5.Open the sunroof about half way and remove the silver strip at front of opening, then remove the front ceiling piece. Take notice which side of the silver strip is front so you can reinstall later.
6. Now the way to remove the headliner is to pry it out from the back windshield, once you've got the back out, the whole thing should be push to the front and it come off the sunroof opening. I was not able to take the headliner out of the car, so I laid the front seat down and left it in the car.
7. You should see the sunroof pan and the bolts that holds in onto the roof. Close the sunroof, you have to plug the switch back by the rear view mirror.
8. Remove all the bolts including the one holding the cable which opens and close the sunroof. But don't remove the cabel. You'll need some help or something to hold the pan up.
9. Once the pan is loose, remove the 4 rubber hoses which carry the water out of the pan.
10. Once the pan is lowered, you'll see the tar link padding on your roof. Scrap it off with a plastic scrapper, a little heat will make it soft, too much will mess up your paint.
11. Be careful not to damage the foam surrounding the pan, if you damage it, water may escape onto the headliner when vehicle is moving.
12. Make sure to remove all that tar crap and wipe the roof with some paint thinner to clean all the glue. Make sure you place some newspaper in the pan so all that crap will fall on the newspaper.
13. If the sunroof shade that slides back is damaged and some of the fabric is torne, you can glue it back. I got some Locktight glue from Walmart, it's heat resistant and very good. I even glued the rest of the vinyle interior that had falling of. You may have to cut some fabric strip about 1.5 inches wide and 1 foot long to glue on top of the existing fabric on the shade to help hold it down. Of course all of this glueing is done on the top side of the shade so it can't be seen from inside the care when done.
14. After everything has dried, over night, put everything back and clean any dirty spots with water and soap rag.

I found this for the W123: http://www.peachparts.com/Wikka/W123SunRoofRepair. Can someone tell me if the W140 process is / looks (visually) substantially the same. Thank you.

Hello:

Does anyone know how to pry the sunroof liner from the metal panel?

I see the four white plastic rivets, but cannot figure out how to seperate the two panels. I was trying to use a butter knife, but such that the interior headliner of the car is narrower than that of the sunroof liner, but liner does not have any slack to be pulled down, and only one of the rivets appears to be loose, but even in its state, there is not enough room down form me to remove it from the socket.

Thank you, JD.
