i had this problem the watr is geting in from behind the polen filter housing. to fix this isue remove the polen filter and unbolt the housing(2 bolts) get a tube or sealent and seal all round the hole and then replace the housing and bolt into place this should stop the leak.

A Comon fault on the mondeo as someone has already replyd is the pollen filter housing letting in water
its located below the black plastic pannel below the window wiper arms on the left hand side of the car

Apparently the pollen filter (on the bulk head under the bonnet) can sometimes have a faulty seal causing water to leak into the passenger compartment. Try changing the filter or make sure it is sitting correctly in it's housing
