Default Air Leak

This may work.
Your rubber seal has probably hardened up.
Go to a drug store and buy a bottle of glycerin. It is very inexpensive usually comes in a 500ml bottle and is a clear thick liquid.
Rub a fair amount of the glycerin on all the seals around your sunroof, use an ample amount, so the rubber is soaked.
Let it soak in for 1/2 an hour or so, then wipe off any excess.
Glycerin is the best thing for rubber seals, you can do the same to all your rubber seals on the car, doors, trunk, hood etc.
If you do this glycerin treatment about twice a year your rubber seals will stay soft, seal properly and last for many many years.

Glycerin is the best thing for rubber.

Well i know you didn't search Because this is a common problem. The seal never really works well ... or for long when trying a repair. Replacement is usually the option. One out of 1,000 were able to make a small difference adjusting the sunroof slightly. For more info:

and good luck.

i wouldn't worry about the slight problems.... worry when its a big problem. i.e. you find yourself with three wheels one day

little to none.

you can remove the trim and slightly persuade the sunroof to close tighter by adjusting the mounting screws.

hope i dont get flamed, but here goes.
if i use the tilt option on my sunroof, then close it- i can hear air getting in, or at least wat sounds like it, kinda like a soft whistle.
if i open the sunroof just a little, then close it back (vs. up and down with the tilt) it seals tight and i dont hear anything. is it just me ?

Default Sun Roof adjusments.

There are a number of adjusments that can be made to the sunroof glass.
Up, down via shims, sideways and front to back.

What this site needs is a place to go for the manuals on these cars.

I spent $250 on the workshop manuals for my 93 SC 400.
It was my 1st purchase after I bought the car.

Has saved me the cost of the manuals at least 4 fold in the 3 months I have owned the car.

The 1st thing you do when you purchase a car that you do not want to be paying a dealer mechanic $90 an hour to fix for you is to purchase the workshop manuals.

It is the best investment you can make in your car.

I have just the opposite. If I tilt up a little bit after closing the sliding type it's sometimes quieter. Of course, then it won't slide open again because it's not smart enough to untilt first, and usually I'm not smart enough to remember either...

Default Adjustments

Will have to scan the Workshop manual for those.
Not sure how to post the scans here so bear with me.

correct, i have posted about this before. The problem is that when you adjust the mounts (shims) you really don't get much for your time since the rubber is deteriorating, but hey,..... if you have a day to blow it'll net you a few extra weeks or so without windnoise.
