Interior problem
1996 BMW 840 V8 Two Wheel Drive Automatic 62000 miles

i just bought the car from a dealer and on the day that I got it home, while it was standing on my driveway I noticed all windows were steamed up on inside. When I investigated I found condensation was dripping from all windows and the carpert on drivers side was soggy with water. The car was subsequently checked out by another dealer who tells me that its definitely not the sun roof leaking and nor is it the drain holes underneath the hood where the pollen filters are as all of this was checked while somebody pressure washed the car. Any ideas as to how the water came to be inside the car?

Check the heater core. Sounds like it is leaking and needs replacing?
