I have an 06 Vectra C (Facelift) with Climate Control. I have discovered that my drivers side footwell front and back is full of water. Bulkhead drains are clear, pollen filter changed but was dry. Found what I think is air con drain on bulk head near to power steering fluid resevoir (slightly drivers side of centre). Did appear blocked and let go of a lot of fluid when squeezed. Any ideas???
