Hi I have a 2006 RX300 3.0I Auto Petrol and have got a problem with wet carpets on the passenger side of the car in the back. They have started to get wet in the front as well. Don't have a sunroof and not sure where the water is getting in to the car. The rubber round the door's are good, the window's are shut and not leaking. Has anyone got any ideas where I can look? Please help, the carpets are starting to get marked where they can't dry out at the moment with so much rain we are having in the UK.
