Just thought I would make other aware of an issue that apparently common to the Focus range.
I have a Mk 2.5 Titanium, and recently when washing it a drip of water has appeared inside the windscreen from under the interior mirror and was running down to the dash. At first it was only when I washed the car, but got worse so even when it rained it would happen.
At first I blamed the aerial on the roof, and I sealed it 3 times, but still it leaked.
The next stage was the carpet on the drivers side started to get damp.
I called Autoglass as the only other place it could leak was the windscreen, who were really unhelpful. They said they could not remove the screen as their sealant was incompatible with all others and I would need to pay for a new screen at a cost of £799 because I have a rain sensor and it's heated. Sod that! I even asked could I take a hammer to it then get then to fit a new one on the insurance? No, because you've made us aware of it now...bunch of w***s!
Next I called National Windscreens, guy was really helpful and he dispatched a technician to remove the screen and refit it for a cost of £75. When the guy arrived, he said he knew exactly what the problem was. Apparently there is a wire that is connected to the heated screen at the top of the screen in the centre. Through time it "wiggles" about and causes a gap in the sealer and hence the leak. He pealed back the headlining and sealed the gap, all for £40.
So anyone else who has this problem, or maybe just damp carpets in the front should check this, and gibe the helpful guys at National Windscreens a shout.....
