GTV6 footwell leak: source partially identified but not entirely...
I've got leaks in my GTV6 footwells when it rains. Which I'd like to avoid, especially on a car prone to rusting out...
I have identified the main source of the leak, but cannot find how to stop it.
I experimented by covering up the two black plastic air vents between the bonnet and windscreen with duct tape (obviously not whilst driving) during a period that we had a bit of a wet spell.
During that whole time: no leaks, footwells dry.
So... Does anybody know the routing of whatever piping is under there; how it's getting from the vents to the footwells?
I had a similar problem with my Giulia. Turns out the same culprit - rain drainage between windscreen and bonnet - had a pipe that was routed directly down, through the firewall into the cockpit, then bent back outwards, through another hole in the firewall into the engine bay then straight down. In that little section that was within the cockpit, the pipe had perished and the water was dripping down. I'm not usually a duct tape bodger but in this case it has worked very well.
Back to the GTV6 - any ideas?
