The car's been sitting in the garage drying out for a couple of weeks. We had a big dump of rain a while back, and when I came out to the car there was a huge puddle of water on the passenger footwell, and the roof lining in the front left corner was soaked. There was even a couple of drops of water on the outside of the passenger-side 'face-level' vent - as if it had been dripping down there from the roof lining above. Bummer.
So, with the battery disconnected, and the doors open, things have more or less dried out. With a couple of hours to spare this afternoon I thought I'd see if I could find the leak.
I'd read about a leak which can develop in the roof seam/weld just above the windscreen, so that was my 'target'. I took off the roof finishing strip on the passenger's side, and...... no real sign of a leak there.
Then, as you can see, I removed the windscreen side trim, and the upper windscreen finisher. There was nothing immediately obvious until I investigated the windscreen itself. Ahhh.... says I, closely followed by f**k.
The windscreen is no longer even vaguely attached to whatever sealant was used.
What you're looking at is actually the inside of the windscreen. I think it's possible this was leaking a bit!!
I wonder if, in use, the force of air against the screen is pressing it against the seal, so it doesn't leak much. Sitting stationary = lots of water...
So, on the plus side, I got this far without damaging anything except for a couple of the upper finishing strip clips, and I've found where the leak is most likely coming from.
On the downside I now have to decide what to do about this. At some stage I think the windscreen's been replaced as it's not a heated one, though I do have the heated screen button. I reckon this also meant the screws under the side trim were not nasty lumps of rust.
I'll now need to remove the windscreen plenum chamber to check if the heated wiring is (still?) in place, and perhaps when it's all stripped down to that level, maybe take it to the glazing guys and get them to bond it in.
Ho hum. At least I've found a leak, though that's not to say that there aren't others......
Edited just to ask.... is there any way to check for sure if the car should have a heated windscreen, of if this one is original? I've been deciphering my VIN no. and came up with something that looked like a build sheet. This said "no htd seats/screen" - which seems conclusive - but as I say, it does have the switch for one on the HEVAC panel. Would they have fitted the wiring and switch on the production line, and then fitted a non-heated screen??
Thanks as always.
