Really does sound like your aft drain holes are clogged. When I had a 740, during heavy rains, I could actually hear the water gargling through those drain holes.

 

Hey many thanks rspi, I'll look into it. Also, in the last rainfall the sunroof leaked on to my head for the first time- which is good!, gives me more info. Thanks again.

 

$5 silicone gel around seal should do it. Way cheaper that way. Dries clear.

 

[QUOTE=rspi;192311]They have drain holes forward and aft, all 4 corners. If something gets in the drain holes, water wont drain out when it seeps in between the seal and roof frame.

You could have a seal leak along the glass edge like I did. It may be dripping on your shade, then leaking into your light assembly. Is your roof liner wet? Check that next time it rains.

It's pretty easy to take the glass out and install another one that has a good seal. I purchased a sunroof with a good seal from a salvage yard for $50. When I went to pick it up they asked $100 for it but I reminded them they told me $50 so they honored that. The problem was that the mechanic gave me a roof for a 850.

I would suggest taking a good look at your sunroof while it is raining, slide the shade all the way open, and see if you can see water dripping in on the glass edge. If you can not see water dripping in, it is likely a drain hole problem. If you see water dripping in, it is likely the seal.

 

I’m new to having a Volvo 1997 960. I recently had an issue while working all day with a lot rain accumulation in my drivers side floorboard. My mechanic ran air through the sunroof channels. No rain in the front. I was sitting in my car, during and I kept hearing a slight feint dripping sound. I couldn’t figure it out? However, I go to pull off tonight, and I hear water stream wrapping against seat. Look back to discover anything the car surges forward, a stream of water comes down in the corner of the backseat, on the passenger seat side? Are there more channels he didn’t know of, or could it possibly be leaking from the back window seal? Let me know if you have any suggestions etc.through experience and troubleshooting the issue.

Location of the leak from falling onto the seat.


Possible entry point of leak?
