'92 940 GL with 218,000Km. In heavy rain or going through the car wash (with under-body spray) there's no indication of any water ingress, but twice now in light rain the carpet behind the driver's seat has become wet and the car ends up smelling like a wet sheep until I dry it out. I asked Volvo to check it out and they did the obvious (without unbolting anything) and found nothing. Since the door sills don't get wet I suspect it's coming from below, but there's an exhaust pipe I can't see past; however, you'd think the problem would be worse in heavy rain if it was coming from below, wouldn't you. Has anyone experienced anything like this?
Cheers
Andrew
