Sorry, I figured out later that what I ment was: without drilling holes in my roof (At the 4 corners of the sunroof)

Hows your hardware look? Are the rubber gaskets around sunroof glass attaching hardware all in good shape? What do the front sunroof tabs look like? Are they nice and tight? Do they tabs have the factory coating on them?

Easy answer? Get rid of the sunroof?

Hardware is brand new from fierostore. They were mint when I installed them and the sunroof always leaked.

Edited for specifications: -New tracks, new seal, and new tabs

I actually though about it, but don't quite like the idea of having to repaint a roof. :/

I wanna say that I read somewhere that for some odd reason GM decided not to drill these holes on the fiero, they drilled them on other GM cars with moonroofs. I also wanna say that till now nobody can say why it is for sure that they dicided such. Perhaps it was trust in the seal, perhaps it was cost cutting? I would love to find out which it is...

Ok so I've tried a couple of things:

First I took out the weatherstrip I had, ripped it (It had a little crack at one of the corners and I pulled too hard.) Cleaned all the tracks from old weatherstrip adhesive and then I've begin the testing:

Notes:
All hardware is properly fixed, I used spacers under the latch to lower the glass (The way the adjustment is done by the Fiero Manual). The latch has been replaced for one that the little pins weren't bent. I have an other brand new weatherstrip that i've been using for the tests, has never seen rain and was never installed.

Tests:

#1 I put the new weatherstrip in place, at some place it was sealed, at other places there was no friction at all.

#2 I placed shoe laces against the roof pannel, on the tracks and under the weatherstrip. (It's like if you would install the weatherstrip normally, then pry the side of the seal to insert the shoe lace without removing the weatherstrip from the track.)
Result: Nothing changed, the restrictions were the same everywhere as the test #1.

#3 I placed shoe laces between the tracks and the weatherstrip to raise the whole weatherstrip an make it balloon a little more.
Result: Nothing changed, once again the restrictions were the same everywhere as the test #1 and #2.

#4 I placed speaker wire the same way as the shoe laces in test #3. Wire being more rigid and a little bigger, it should make it balloon even more.
Result: Because the glass is on a pivot point (The front fastners on the glass), the glass was toutching the weatherstrip at the front too early to be able to reach the end of its rotation. In other word, the glass couldn't even fit! Then I've tried removing the front wires and then the glass could be inserted but couldn't rest properly on the weatherstrip. I removed the sides which helped for the placement but now I had a huge gap on the side because the back was raised.

I ended up removing everything cause nothing was working, put the weatherstrip like it's supposed to be normally but then I noticed strange things. The weatherstrip makes good contact in the front half of the sunroof and only on the 2 corners in the back. To show you what I have to work with, I took 2 pictures that is very explainatory of my problem. Keep in mind that this is a BRAND NEW weatherstrip, never used!

Here's the biggest gap I have:


Now, you can see its a big gap, but wait for the next picture....:


YOU CAN SEE THRU THE WEATHERSTRIP AND THE GLASS! :O It's deffinitely not normal. I have the same problem on the other side of the weatherstrip. The back though only misses a little bit of friction, not too much but the side are just bad!

Now I don't know what to do anymore, anybody has ideas or something?

Good luck, I've been fighting gap issues for 8 years now ever since installing a new seal (2 in fact, one from Fiero store, one from GMPartsDirect) and nothing anybody has said has had any effect. My friend's sunroof that fits fine in his car, has the same gap as mine when installed in my car.

As much as you're not helping my moral, as much it tells me not to keep my hopes up too much. :/

Oh, and I tried with 3 different sunroof glass, and it wouldn't make any difference.

So if it means it's not the glass, not the hardware, not the seal... (Cause I tried more than one of each) Then the only thing left in the equation is the tracks, the roof pannel or the frame itself. Right?

You could also try what I read awhile back here on the forums. Someone threaded a 1/4" or 3/8" soft nylon cord through the seal. (the seal is hollow) They said it work like a charm.

Good Luck,

It looks asthough your not getting that gasket seated properly,
when i got my fiero store gasket i had to trim alittle material
off of eack outside corner for it to seat right. it kinda looked
like they didnt quite trim it correctly
