Default sunroof fix

Iíve been searching all over for sunroof fixes... my sunroof jammed at an angle the other day and now i think itís fubar. if i try to close or open it i get clicking... i removed the glass, liner, and motor and it appears the drivers side rail is stuck.

is my only option to pull the headliner and replace the cassette? anything else i can try? iíd be happy just getting it back in a closed position so i can bolt the glass back in and have it be closed instead of stuck open. i canít seem to move the track by hand on either side tho

really donít want to pull the headliner any ideas?

thanks

You've got either one of or both of the plastic guide pieces broken on either side (two different pieces on each side.)

In order to inspect, remove the glass from the top.

Here's a great DIY that I used:

Thanks for the link, that shows me how to remove the "wiper" in the roof cavity. I still think my problems are greater than the sunshade. My sunshade and accompanying pieces were all intact and in the track. It seems to be the actual glass track that does not want to move and makes the obnoxious noise. The drivers side is stuck forward causing the wind deflector to be pushed down on that side. When actuating the sunroof with the motor still installed the passenger side moves just fine and the drivers side just clicks and doesn't go any where. Maybe if I get the "wiper" out I'll find some shit jammed back there...

Good excuse to go carbon fiber roof!

I kid, hope you find a solution. I doubt it's electrical in your case, but I had sunroof issues once on my old E46 and following the reset procedure I found on the forums solved it for me. Might be worth a shot.

The reset procedure is simply holding down the switch for 10-20 seconds while it goes through the motions... mine cant go through the motions at this point. I need to un-**** it.

Sorry I'm no help to your issue, but once I heard my sunroof getting "crunchy" while opening/closing, I simply closed it shut and unplugged the motor, done with that and not going to deal with it.
hope you find the solution.
I'd do the carbon fiber sunroof panel and have it match painted for weight reduction, but it's probably not worth it on a street car.

Default Re: sunroof fix

I had the same problem awhile back.

In my case the cassette frame was broken in the right front corner. Not sure what to call the internal part that pulls the sunroof from the motor but the cable/chain is coming out of the cracked cassette when moving the sunroof back. works fine to lift the back part of the sunroof. I was lucky enough to close the sunroof and disconnect the motor and leave it alone as a future project.

My suggestion would be to take the motor off and see if you can manually close the sunroof. I am not sure if it works but it is a lot easier to go this route than to take down the headliner.

I have the motor out and i canít move the tracks. The passenger side is about 1/2 way back and the drivers side is almost all the way forward. I can get the passenger side to move but the drivers seems stuck. Iím going to try to clean it really good and get some lube.

any idea how to move the tracks with the motor disconnected? is it possible to move them independently?

Default Re: sunroof fix

Looks like you are in for some headliner fun. The cassette plastic frame breaks and then the cables do not run properly. Can't open or close manually either.
I picked up a replacement from any E46 sedan or couple at a pickNpull. I think I paid $30 for the entire cassette. Removing it took maybe half hour. I also learned how to properly remove the headliner while removing the cassette. It was invaluable when it came time to carefully remove the headliner. I took the entire headliner out the passenger door. I then replaced the cassette, installed the glass and made everything work properly before reinstalling the headliner. All the pillars have to come out. I suppose you could just lower the headliner but that just makes the job more annoying and difficult to adjust.
I should also note that I did not reinstall the blank panel under the glass. It is just a good part to cause problems all over again.
