I'm trying to figure out why my sunroof is adding so much noise to my cabin. There is a significant noticeable difference between sunshade open vs. sunshade closed, which leads my sunshade to always being closed. This is in my 1997 Buick Park Avenue Ultra. I distinctly remember doing the sunshade open/closed test in my 1998 Aurora and noting that there was no discernible noise level difference (I did the same test in my Jeep and also notice no noise difference). I already replaced the sunroof seal and readjusted its parked position with absolutely no difference, and I believe the part number is exactly the same as the Aurora.
Can someone post up what the markings on their sunroof are so I can compare? Maybe I'm better off stealing the glass from an Aurora, as I can't think of anything else that would lead to the described issue. I even tried stuffing a jacket into where the sunroof retracts in case the sound was coming from the roof area, but the sound seems to be coming right through the glass.

Strange, but the sunshade will be an insulator from light and sound. If it's making wind noise - water may be getting in also...  What markings are you looking for? |

My Cadillac SRX is the same way, sunroof is real loud with the screen open, it's an aftermarket type that is in a bunch of Cadillacs. There were also a few Auroras that had aftermarket dealer installed sunroofs. Maybe your Buick is an aftermarket roof?

Try taping around the edges and see if that helps. Clear packing tape would probably be a good choice. That would indicate something still isn't right with the seals. You can do the credit card trick - slide that around the edges and see if there's any gaps. Also, it takes time for a new seal to conform properly, but you can speed it along with a heat gun ... Next step would be to liberally apply silicone lube. Rub it on thick and work it in with a finger. Repeat as needed. Worked wonders for my door seals.  |

I don't have any reason to believe the sunroof is aftermarket. Everything looks factory and it seems to function the same as the one in the Aurora. How might I tell?
I tried taping the seal on the outside and driving around. I thought it seemed to make some amount of difference, so I replaced the seal. I think it was in my head.
There is a etched stamp in the glass toward the back of the sunroof. Mine says:
TEMPERLITE
AP Tech
M2L4 A23
DOT-376

X2 on the silicone grease! Once yearly on the door, trunk, and sunroof seals.
CF5 is the RPO for factory sliding glass roof...

I don't recall the sun shade being open or closed making any difference with road noise on my '98 but it sure does on my '95. That car had a massive water leakage problem when I first got it but it was corrected when I took it to a glass shop and they repaired the drain lines. I still have a moisture issue with the trunk that has killed a CD changer and two sets of rear speakers and left rust on quite a few tools.

I just had oak leaves stuck by my wipers creating road noise for me.

On the very rare occasions that I moved the shade back, I didn't hear any difference in noise between the shade open & closed.

I just checked and I have the CF5 RPO code. So it looks like its factory.
Human, would you be able to compare the markings on your two sunroofs to the ones I posted? That's interesting that two of the same car would have such varying degrees of road noise coning from the sunroof.
It just doesn't seem right for a Buick which is why I think there's something fishy.

No way to check the '98. I haven't owned it since 2009 when It was totaled and I let the insurance company take it. I have no idea of its fate after that. I bought the '95 three years later to replace it and in some ways wish I hadn't. One thing I can say with certainty is that '98 was all around a much tighter car than my '95 is. Of course, the '95 is now 21 years old (manufactured in December 1994) and the '98 was nine years old when I bought it and eleven years old when it was wrecked, so the one I have now is twice as old as the other one was when I owned it.

Maybe you and someone with a '98 or '99 Aurora could chime in and post up what the markings on their glass or verify if they match the ones I posted?

Could I get someone with a classic with a moonroof to post the markings on their sunroof glass? Preferably a 98/99. I'm still trying to chase this down.
