Re: Scuttle Drain DIY fix

I haven't noticed any exhaust fumes but I'll try and get a picture of the hole so you can see what I'm talking about (in case it's nonsense).

Re: Scuttle Drain DIY fix

If the weather's decent this weekend I might try having a look around the blower unit in case I can see any moisture.

Re: Scuttle Drain DIY fix

Brian- I will take a photo of mine today if I can so you can compare . As you can see from the original post I am no Patrick Lichfield so they will probably be upside down!!
When you stand back and wonder at which frenetic Italian designed that! as I did , you have to think about what has to happen in this scuttle area. Intake air / get rid of water, simple. The flap valve solution is a pretty simple way of allowing this without allowing "stuff" from the under the car to access the inside of the car. It is probably a cheap way as well, but I will bet a bee to a bulls foot if you had to get one from a dealer it would be ~ 20

Re: Scuttle Drain DIY fix

Well here goes- got a photo with some of the c**p showing what will happen if you park under a tree.
The rubber flap valve can be seen,just under the bottom of the pollen filter with the red drain pipe going down into it. At least you can see one end of it under the mound of decaying rubbish.Click image for larger version

My other post was wrong there is only one flap valve, on the passenger side , the scuttle is shallower on the drivers side to allow for the master cylinder and steering column etc.

Re: Scuttle Drain DIY fix

Just noticed that the red pipe is a bit too longand it is holding the bottom o the flap valve open. the grey bit at the bottom of the pipe is the road surface under the car!!! I will shorten it a bit so its just in the top where there is more room and it will still direct the water past the lip on the bottom of the pollen filter frame. This is where the short original tube was directing the water before the fix.

Re: Scuttle Drain DIY fix

Can someone tell me what the upper end of the tube is connected to. There's no pipe in mine at all and I'm plagued by misting with heater on but aircon off.

Re: Scuttle Drain DIY fix

There will be a small hole in the scuttle where the water gathers on the passenger side. If you can't see it then rub with your finger - it's probably full of mud. This hole is the back of a short stumpy connector on the underside. The original tube just pushes onto it from underneath and (I think) is just held by friction. If you're going to use something a bit wider (a very good idea) then it will need some kind of packing and/or clamp to stop it falling off.

Re: Scuttle Drain DIY fix

Duncan - if you check out my first post you will see the photo I took of my "fix". he small hole in the scuttle is plain to see so you know where to look.
My guess is that the "flap " valve under the pollen filter is blocked as well and needs to be poked out with a screw driver. Water is collecting at this lowest point but not escaping and moist air is getting into the car via the pollen filter.

Re: Scuttle Drain DIY fix

I see the small hole just above thw orange pipe. Mine definitely does not have one, clean plastic all the way along. Took pics to check inside, nothing, nadda, zilch. Mine must be different. Drain hole on both sides is clear and when I put hose on window there are no drips near the pollen filter!

Re: Scuttle Drain DIY fix

So if you squirt water on the windscreen where does it go?

Are you by any chance the owner of a rare-as-rocking-horse-poo UK facelifted Croma? Does it have blue or red Fiat badges?

...or is it an older Croma, in which case you need the other forum section. This forum is for the one that looks like the picture in my avatar, i.e. like a posh van.

Re: Scuttle Drain DIY fix

2005 blue badge. Water drains where wipers are. I can categorically state no drain hole in plastic below windscreen. Just had windscreen replaced, I was shocked that it was in stock, windscreen guy cleared scuttle hole on drivers side but I still get misted windows when heater is blowing to screen, only clears with aircon on. Maybe problem with heater matrix in which case I'll stick with aircon on to clear screen.

Well this is a conundrum and no mistake. One thing is really puzzling me was when you said the window screen man cleaned out the drain on the drivers side?? Is your car LH drive????
If the water is getting away then it may be the flap valve in the bottom of the scuttle that is blocked . This will cause water to lie in the area just under the pollen filter and damp air will be drawn into the car.
I have loaded the photos of mine earlier in the thread this should give you an idea of where to look. Check it out and clean with a screwdriver to ensure water can get away .

Re: Scuttle Drain DIY fix

Drain flap under pollen filter was always clear. Didn't know there was one on drivers side (rgt side) until windscreen guy told me about it. Did see the puddle but he cleared it for me.

Re: Scuttle Drain DIY fix

So which way do the wipers go? Is the unwiped bit outside the arc of the wiper on the driver's side or he passenger's? Is the big wiper on the driver or passenger side?

The reason I ask is that I would have thought that a LHD scuttle should only fit LHD wipers.

You've got a very special Croma there. As theorised earlier by Tarquin, it's probably on the left as the car would tip that way if parked on a road camber pointing the right way.

I think we Croma anoraks need some photos!
