Wet Floor from Air Conditioning Unit

Hi,

Our D4D Prado is barely a year old but has an intermittent fault. The day after we took delivery of it, we returned it to the dealer as the floor on the front passenger side was getting wet with air conditioning condensate. The dealer's people couldn't really find anything wrong with it but thought the condensate rubber hose was routed incorrectly.

We didn't notice anymore leaks for about 11 months and then we found the floor well and truly saturated. The padding under the carpet took a couple of weeks to dry out. It is inconvenient to take it to the dealer so I put a hose clamp on the condensate hose where it comes out of the a/c unit. There were no leaks for 3 to 4 weeks but it is leaking badly today again.

I took the cover off underneath the glovebox again and found the condensate was not leaking out of the hose connection but out of the bottom of the left-hand side of the a/c unit and dripping onto the hose and thence onto the floor. I thought there might be a blockage in the hose or where the hose pushes onto the a/c and this was causing the condensate to back up before leaking out of the side of the a/c unit. But, in the end, I could not find any problems. The strange thing about it was when I put the hose back on and started up the car, the leak had vanished.

Has anyone had this problem and, if so, what was the solution, please?

Regards
Glenn

Not 100% sure how the A/C drains are with the Prado, but in my Commodore I am forever getting wet feet. If you look around in the transmission tunnel area you should find the hoses. Ensure they are located to the metal work correctly so not to leak into the footwells. Also poke some wire or a screwdriver into them from underneath to ensure they are not blocked.

Could be as simple as a bit of shrapnel floating around in the AC unit and intermittently blocking the drain outlet????

If its possible, stick and airline up the end of the drain and give it a blow.
If it was after a few years I would say that its dirt or algae/ crud build up, but from new it points to a bit of left over plastic or similar from manufacture.

I would keep logging the fault with the dealer tho.

When you pull up somewhere, do you end up with a puddle near your front passenger wheel after running the AC??? We get a faily decent puddle in the carport, like about the size of a beer carton..(patent pending on the standard of measuring)

I get ants blocking the hole up in the ol lux all the time thus the wet carpet. A bit of wire usually fixes things.

Definitely a warranty issue. Don't be put off by the dealer not being able to find anything wrong.

It leaks so there is something wrong. Make them find the problem and fix it.

Had the same problem with my Prado, took it to Toyota, turns out all they did was to run some sealant over the joins in the aircon box, problem solved, turns out the water was leaking from in between the air con box housings, I was just lucky I had mudgrabber mats fitted, they court all the water & the carpet didnt get wet
