Do you have those extra pics?
Have identical problem in my 2010 ute. My passenger-side pillar was FULL of water. I pushed my finger through the vertical face of the pillar (easily) when discovering bubbles; I reckon 3-500mls of water fell out.
Everyone's been scratching their heads. Doesn't appear to be anywhere water can get in.
Now I know there is, so thanks. The most promising idea so far has been a/c leak/condensation through firewall, which I'm pretty sure isn't physically possible. Am planning an a/c leak test just to be sure anyway..
Does water from exterior flow straight over that grommet from windscreen/whatever? Or across?
Wouldn't take a big leak to fill up like that over time. But a waterfall flowing straight into the top of the grommet every time it rains...
Was there any indication of deeper structural damage ie chassis or firewall?
Typical Ford. The cost of a cable tie to secure the cable might've saved some stress and $$ on repairs..
What was the repair cost, if you don't mind saying..?
Thanks for any help. Was starting to think I was gonna have to sell it for whatever I could get just to be rid of it.
