Sunroof Seal
I found that there was a TSB released in 1996 for the early model
sunroof seals, replacing the original sunroof seal with a newer
one-piece design. The part number is 12371670 and it lists for around
$71. I ordered mine through www.gmpartsdirect.com for $42 plus shipping.
For you do-it-yourselfers out there, it took about 30 minutes to
install. Remove the 3 phillips screws from the front edge of the sunroof
and slide the trim ring back. Open the roof to the vent position and
remove the 3 phillips screws on each side of the glass... the glass will
lift right out. The old seal pulls right out of the channel that runs
around the edge of the glass panel, but there is quite a bit of adhesive
along the side where the two ends of the seal join up. You've gotta
scrape all the adhesive out of the channel before installing the new
seal. Once that's clean, press the new seal into the channel... no
adhesive is necessary. You'll need a rubber mallet to set the seal
properly. Once it's in, reintstall the glass panel, but only lightly
tighten the 3 screws on each side, as you'll need to cycle the roof
closed a few times as you adjust the glass height and position. The
panel should be flush with the top of the car, and the back of the glass
should be just a little higher than the front - about 1 mm or so - to
keep wind noise down. With the roof closed, you should be able to slide a
business card all the way around the sunroof (between the roof and
glass panel) with only slight drag. Once you have it all adjusted,
tighten it up and cycle the roof a few times to make sure everything's
OK.
For me, it was $50 and an afternoon well spent. Wind noise is gone
completely, and now that the drain hoses are fixed, it stays dry, too.
If anyone would like full instructions from the shop manual and/or the
TSB info, let me know.
