You have a leak in your air conditioning compressor Your system works on the reheat principle All air passing through the system is cooled and reheated before it enters the cabin this sould be dehumidified air but it passes through the heater core and sence the air is not dehumidified you are getting condansation as the air flows the heater core that is heated by the engine heat and the water is from condencation because of the leak in the ac compressor The unit is a press fit in the center of it and fials unfortinatly a lot with this disgien of compressor

Water leaks in above and behind dashboard passenger side..onto floor board when it rains. Took it to dealer last time..charged 80 bucks told something was clogged but they would not tell me how to remedy...

There is only one thing that will cause it if you have a Sun roof and that is the water drain pipe from the roof to the wheel arch were it drains out and this bunged up,so blow it out with air compressor or high water pipe.
IF no to sunroof then its the windscreen leaking at the top and you might not beable to see it it will be at the top But dont try and fix it as the screen has to come out to do the job correctly.
But if only leaks water on floor and not on top of dash it could be the vent under windscreen were the wipers go and the vent drains the rain also to the left and right side of wheel arch, then they can be blocked and overflowing into the air box for the heater because that is where the air comes from when on FRESH AIR for heater..So check them out and do as required it shouldent cost you anything unless its the screen out..Job Have a goodday Let me know how you get on Ron

Water on the front driver side floorboard

It's not the air conditioning because the problem happened after a rainfall. The air conditioning would cause a wet rug while the air is on and it is very warm and humid outside. Then I could see a plugged drain causing the issue. It may be a leak around the windshield area or sunroof if you have one.
Start your car and put your fan on high. close the windows and doors. Spray a soap and water solution around the outside of the car starting around the windshield area. Look for bubbles forming. When you find the bubbles you found your leak.

Water under driver side floor

It may be due to the air conditioning hose being blocked. Therefore the water must be backing up into the vehicle, under the carpets and into the back seats instead of flowing out

You are correct. The water that you are seeing is the condensate that is drained out on the street when the A/C is on. Look at the passenger side of the car, under the dash, close to the center. You will see a black rubber tube coming out of a box, and it will poke thru the firewall, towards the front on the passenger side. Remove it, expect to see water drain out on your floor. Clean it by running water thru it with a garden hose or something like that. Reinsert it and poke it back thru the firewall. This is very common for the drains to plug up.
