Water leaking in floor board when a/c on in mazda mpv 2001

You probably have a plugged drain outlet for your under dash heater/AC unit....system is designed to drain moisture from AC evaporator core via the drain outlet...drain outlet is located under the hood

Thru the firewall and is a (approx) 1/2" dia rigid plastic tube. Sticks thru, toward the rear of the engine, about 1". It's located so that it spills (nice!) onto the most rear engine/tranny mount. There's evident rust to prove it. Try to remove it and the water should pour out . Try to locate the drain by looking where the arrows are pointing to on the pictures I am supplying

I had the same water leak issue with my 2005 uplander LT. I seal around the drain tube with RTV and I actually put a flexible plastic tube on the drain at the firewall to make sure water wasn't coming in. Although this is a known common problem. It did not fix my water leak. What I found is the body seam weld at the driver's side kick panel down by the parking brake pedal was leaking. Pull the carpet back and have someone spray the windshield with a water hose and look for leaks in this area. I had to loosen the driver's side fender to pull it away enough so that I could RTV (sealant) all of the seams in that area. I have not had a water problem since.

Where is ac drain hose

Passenger side firewall, down low. Easiest if you pull the inner fender well to see it, unless you have it on a lift.

There is a TSB on an elbow for specific model years, AC drain TSB 07-13-5

Picture of it through the passenger wheel well, with the inner fender removed. This is with ths TSB p/n : F3LY6A614A installed

This is before the elbow is installed

The drain line is plugged on my 2007 corolla lwhere is the drain hose?

What drain hose? If it is for the AC, in the engine compartment on the passenger side, the is a black plastic box on the firewall where the AC / heater blower fan is. At the bottom of this box is the drain hose. The box houses the AC evaporator and when the AC is running, water condenses on the evaporator and is drained through the hose.

There is water the fills the floor of the passenger side of the car when the air conditioner is running

The AC condensation drain is clogged, when the AC is on water is condensed on the cold AC evaporator core (this part is what cools the incomming air), this water drains out the bottom of the heater/AC air duct, the drain is at the bottom of the firewall under the hood on the passenger side, run a coat hangar up into the drain to clear it.

The front passenger floor gets sopping wet after I drive and turn off the truck after having had the a/c running. It only does this if I had the a/c running. What's going on? 2003 Dodge Dakota 6 cyl. Aoto...

That sounds like the AC condensation drain tube/hose is plugged up.

The AC evaporator/core condensation drain tube is located on the passenger side of the fire-wall towards the bottom of the fire-wall, (it resembles a heater hose that is coming off from the fire-wall and it connects to nothing, and it is just to drain the AC condensation) and it is easily viewed from under the vehicle. Use long pipe cleaners folded in half to clean out the AC drain, and be very careful that the AC evaporator/core, or the heater core is not damaged from using any hard or sharp objects to clean out the AC drain.
