I have an R plate astra estate which is letting water into the passenger footwell. As far as I can see possible sources are the roof bar penetrations, the screen, the air intake grill below the screen, the screen washer hoses, and perhaps the drain from the aircon (since I havn't been able to find it). It's not losing coolant so I don't believe it is that (also it doesn't taste of antifreeze).
I have removed the seat. lifted the carpet, cut out some of the "underlay" in an attempt to dry it all out and trace the source. I am still getting some water dripping down at the door pillar side, and from what I still think of as the transmission tunnel, both probably still draining from the saturated foam.
Does anyone know of any sealing weak spots or drain points which can get blocked in Astras? It looks relatively complicated to expose the bulkhead region where water from the air intakes drains from.
Thanks!
