sounds serious fordgirl.
any codensation from the air con should be drained outside.
does the water smell . could be coolant from the motor if there is a leak in the heater pipes.
if it is from the motor it will smell like coolant ( take the cap off your coolant tank , RHS under the bonnet) and see if it smells the same.
have you checked the coolant level , because if it is leaking that much coolant , the motor will cook.
has it been raining there where you are??
could be a leaking windscreen. might need to be resealed.
should save the water in some bottles to show the guys at ford how much it is leaking.
then if they wont fix it you will have something to throw at them anyway.
