Hello I own a Volvo 740 and after each rain there has been up to 1 inch of water on the rear passenger side floor. Likely on the rear passenger side because of the grade in which it is parked. I have searched for the answers to no avail. I did manage to find check and blow out the sunroof drains which helped none.
Where else may there be blocked drains besides sunroof.
Thanks

Same problem. In my case water was leaking past shield over HVAC fan inlet. Could not figure out how the water got from passenger front to Driver rear. Answer: thru hot air duct under carpet.
Sealed shield with silicone--no more leaks. (except that **&$* sunroof. Pollen plugs the drain tubes.

Thanks. Found the leak. Left of drivers footwell behind vent. Fixed up with silicone rather than ordering new seal.
