Sounds like you may have a issue with the heater core its located under the dash and when they leak crack they have to be replaced they leak on to the floor and cause you to loose your heat
Sorry that was my first guess on the matter please let me earn 4 thunbs up 2 hurts my rating. Have you inspected the seals around the windshield there is a good chance it could be leaking causing it to go behind the dash and to the floor or the seal around the drivers door.
I am confident I can work with you until we come up with the correct fix
I will have to check windshield already check door seal I have spayed asealer around steering column
Also if this has a sunroof it can leak from the drain which is a line that goes down past the windshield
No Sunroof
Any bodyseems in the wiperarm Area that could open up
It could leak where the wiper arm goes on there is a hole under the wiper arm which if got rusted or something could cause this issue. You will want to remove the wiper arm and put water there in the hole see if it goes into the car.
thanks for giving me 3 thumbs up I am glad I helped!
thought had it fix but still leaking

The heater core would leak on the passenger side. Look for a plug missing on the firewall. Or if you or someone added any electrical gadgets and ran wires thrue the dash or firewall and didnt seal them.

New Heater core It only does when it rains
All ready replaced Heater core it leaks only when rains
no it comes up from bottom I have answered this its a drain channel under floor board gets plugged and then water has no where to go but up into the car you need to drill under the car into the channel to allow drainage.
