Leaking Sunroof

Shopping thread moved to talk.

eBay, perhaps?

You might give some of that flowable silicone sealant a shot before blowing the cash on new weatherstripping. Grab a tube from any auto parts place for less than $5 and use the screw-on tip to get it as far in there as you can. It's worked for me in the past for leaky windshields and such. Just make sure you get a nice, even, solid bead in there. You might have to re-apply it a time or two right after it cures because it can sometimes leave little gaps when the silicone flows down or gets sucked down into the joint, but otherwise, it wouldn't hurt to try before spending the big bucks.

Also, you can buy some of that butile ribbon sealant like they use for windshield installations, unbolt the sunroof, scrape all the old gunk off, carefully lay a bead of that stuff around the top and bottom halfs (or heck, even a thick bead of RTV might work), and see if that works.

Anything more than $50 for weatherstripping is kinda nuts, IMO ... but then, my car's kind of a beater, so I'm not quite so anal about details like that.

You dont have to unbolt the sunroof- just pinch the tabs at the back and lift it out.
The whole sunroof comes out.

who said anything about unbolting?

I don't think the silicone will work...i'm nearly positive it won't since the seal on the glass has probably rotted and is falling apart...mine was.

I got my new weatherstripping kit (glass weatherstrip + the part that goes on the car to glass) as a kit from 50resto.com. Here is a link: http://www.50resto.com/products.aspx?searchkey=sunroof&category=MMUSTANG, Scroll to the bottom of the page. Mine for the glass was trim to fit (no big deal), but the one for the body was NOT trim to fit (I got the $89.00 kit.)

HOWEVER, if you don't need the inside weatherstrip (my old one was fine), I would suggest not getting the inside (car to glass) one...at least not from 50resto. The one I got was about an inch short and it doesn't fit all the way around, so there's a gap that's noticeable on the inside of the car. I'll reinstall my old one and trash the new one when my headliner goes back in. The glass strip has been on for about 4 months and seems to be fine so far.

The hole for my factory sunroof is a little off, so the weatherstripping (new or old) doesn't fit right up against the corners very well, so water gets down in there. The car was designed for that however, which is why it has the drain holes down in there to drain water to the ground if it gets past the weatherstripping. HOWEVER, I found that, although my drain lines are working, water was seeping inside the car and leaking around my trim. You know the little yellow things that the little prongs for the sunroof slide into? Water was getting in there and leaking down into the car. I found that out after I pulled my headliner and went and washed the car and watched where the water came in at. I then removed the yellow things and used silicone on them and put them back. I have yet to get the car back out as I broke a piece to the sunroof, but I will have it back out shortly and I anticipate no leaks.

You may have a similar issue. Unfortunately, you have to remove the headliner to get at the yellow things. I can take pics if you need me to.

while we are on the subject, does anyone know if a sunroof was an option on the '93s. I have one in my hatch (leaks like hell, pisses me off), and people tell me it couldn't of been a factory job because they didnt have that option in 93. etched into the glass is some name plus 1992 so if its not factory it was sure as hell done as soon as the car was bought..

My Mustang Red Book indicates that there was a flip-up sunroof available on the 1993's as well. Who told you there wasn't?

Here are some pics of mine (mine is factory 100%):

Here's the glass w/ new weatherstrip:


If your "hole" cut in the roof is rolled and looks like this, it's probably factory:


Here are the yellow things I'm talking about that the water seeps in through:


As you can see, I removed mine, scraped the gasket, and reinstalled w/ silicone:

Note, Be sure and get a good amount of silicone on the bottom portion...I think that's primarily where the water gets in.

50resto is GREAT, but the body weatherstrip in their $89.00 kit was not long enough. I didn't trim it at all, I just put it on:

Note:The Glass weatherstrip is great. Mine was trim to fit, which is not a big deal. 50resto has super fast shipping and generally is a good place to get parts. This is the first issue I've had and I DID NOT contact them as I'll just reuse my old one since there's nothing wrong with it.

They were a factory option but maybe your car didnt originally come with one and a previous owned had an aftermarket one installed.
Ive seen aftermarket sunroofs on fox bodies before.
The glass is a different shape and size than the factory sunroof.

ill post some pics in a bit, its looks like ass because the previous owner tried to seal it up with same caulk and it looks awful plus it still leaks (and i cant open it).

I guess mine was an aftermarket piece, then. Totally different design. I was under the impression, before, that I'd been running a ruined factory sunroof before I yanked it out and put in an all-new (and larger) one...

This is the reason so many of us argued with dealers back then. The two I bought new had to be hardtops, one I ordered, but the dealer had my second one, just like I wanted, but with a sunroof. He gave me 17 reasons why it was so hard to get one without, but I didn't want to get rained on in five years, made him search, get what I wanted. Those things are a hole in the roof, no matter how you cover it.
