Water leaking from a/c

Check the door drain vents in the bottom of the door ensure they are not blocked, when it rains the rain travels through the door at the window seal and escapes through opening,
. Open the door and check underneath. If blocked water fills the door and gets into the car. Also if the car has a sunroof water may be coming through there. If not this try going through a car wash while in the car and seen if you can see it hear any water getting in my

Chances are, it's coming in through the rubber somewhere on your windshield.

Check the rubber for splits and perishing. Any car accessory shop will sell a liquid sealant which you can try to fix the leak.

it is leaking from the outside air intake there is a hold there to clean it on on the passenger side top grill by windshield ask me more will explain

It sounds like the heater core went out on the car, The heater core is located inside dash on the passenger side. It will leak more when the heater is turned on.

Sounds like maybe the ECU had taken in some water. Is your ECM located behind the engine on the firewall? There are two large fuses located on the passenger side wheel well in the engine bay. They are two large (2" plastic covers) over them.

I had a similar leak on a 1995 Accord. I traced the issue to the plastic liner behind the door panel. The seal was broken at the bottom and water would leak from that to the rubber weatherstrip at the bottom of the door that seals at the plastic threshold molding. You can't really see it good until the door panel is removed. The water would drip until it puddled up enough to run over the threshold molding and under the driver's seat. This caused the floorboard behind the driver's seat to be soaked after a rain. I have resealed the plastic lining but of course it hasn't rained since. I'm confident this will solve my problem and hopefully provide you a new place to look for yours.

You could have a leaking windshield seal, and its running down the inside of the dash and onto the mat. Has the windshield been replaced?

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.

the ECU is located on the passenger side floorboard underneath the consold and carpet

Here is what all dealers do to find water leaks, we spray a fine mist of water on the car near where the water might be comming in with a spray nozzle, someone gets inside the car and look for the leak, there is no other way, and I have been doing this 30 years.
