Water Leak on front floor and rear driver's side on 2005 Chevrolet Malibu

I have a 2005 Malibu that I have encountered floor leaks. Up until the storm on Thursday night into Friday in N.J. was concentrated to the rear driver's side. On Friday morning I had a puddle on my passenger front and some water by the accelerator pedal. Any input or help to resolve this would be greatly appreciated.

It is best to look for water leaks when everything is dry. First is the door seal or door, damaged in anyway? I have seen the seat belt having damaged the door seal on many vehicles. Do the doors close flush with body? Ensure the door seal makes good and uniform contact with the door (particularly important if the vehicle has been involved in an accident. You may need to pull back carpets pull back the carpets and sit inside the car (you may need a flashlight) and get a friend with a garden hose to spray water around the door jams to determine if the water is entering the doorway. Then spray water around the windscreen moving around the circumference of the windscreen. Look around the windscreen area and look up from the floor mat area (as best you can) to determine if water is leaking in around the windscreen seal. Is there any rust around the windscreen area or body work? If you have a sun roof there is a drain tube at each corner of the roof to channel away water. A blocked drain may cause water to fall from the sunroof area Water can also come up through the floor pan as you drive through water on the road, if any rubber bung or “seam sealer” has been disturbed or is missing.
it is your heater core-when you use your heat does it leak more or foog up windows?
The windows do clear when the heater is on. What I do hear by the windshield is a sound that is like bubbling or running water. Any thoughts or suggestions on this problem.
