Rain entering cabin

[Walshie]

I have posted about this problem before but haven't been able to sort the problem.
To recap, I have rain water entering the passenger footwell at the front of the car ( right hand drive) I have poured water down the front drains and this runs out ok, I have put an air line down them to make sure they are not blocked, I have replaced the missing rubber grommets to the drain holes. I have had the door membrane replaced even though the door card was dry, I have re sealed the cabin filter casing and have now run out of ideas.
Is there anything I am missing.
The water is entering from behind the dash but not through the screen, it runs down the bulkhead and onto the carpet. The carpet under the seats always remains dry so it isn't the rear drains.
Fed up and at the moment defeated.

HELP

Are all the frunk cowl covers properly installed and present? Battery drain working properly? Fuel overflow draining properly?

A/c evaporator drain clogged ?

No not clogged, and car gets wet when sitting outside the house not being used.

Can you replicate by using a hose? If so I've heard of folks putting dry food coloring in certain areas then doing the hose test and seeing what color water shows up.

Are you sure it's not getting in somewhere round the side windows? I had to get my passenger side windows adjusted to stop water getting in past the front edge and running down the inside front of the door.

Are both of the door liners in good shape and in place? I am talking about the ones between the metal door and the inner interior panel.

Could the seal around your windshield be the problem?

No, I have water tested from below the windshield line, the water drains away ok from the skuttle panel through the drains but some ends up running down the cabin side of the bulkhead at the very front.

[Walshie]

I have tried with a hose and also more specific placement of water to try to locate point of entry. When pouring a jug of water in the skuttle tray, it drained down the drain hole but then seeped through where the heater box passes through the bulkhead. I do not know what is the other side of this and how to get to it.

Just so you know you aren't alone. I get water behind my passenger seat, every time it rains. Drives me bat******************** crazy. Did the hose test, made sure all drains were free and clear, checked seals, and yada yada yada. I finally just gave up, and keep the carpet pulled up behind the seat. If it rains, I keep a small white towel under the carpet. It soaks up the water, and when the weather is nice, I leave the top down during the day and it dries out nicely.

Not the fix your looking for, but I feel your pain!!!!!

Best of luck!

check the front wheel fender liners... perhaps water splashing up from the tires.

Thanks, it is very frustrating, I am starting to feel that way. I have bought a storm cover for when the weather is bad.

Unfortunately no, it leaks when standing outside the house not being used.

Hi need for Speed.
From this it looks like there is 4 drains fuel filler, one either side of battery and no 3 that I didn't know about, is this correct

[Need_for_speed]

I count 6 total: 2 behind the seats, 2 in front (near battery), fuel and a/c.

Oh ok no 3 on the schematic is the AC drain. I take it this is only a problem if the AC is running and not while it is sitting unused.
