Hi, passenger footwell is now nearly as wet as the drivers side! I'm 99.9% sure it's not the pollen filter covers that are leaking and fairly sure it's not the screen. 100% sure it's rain water, so where else can it be getting in for me to seal up!
Cheers
 
Been there, done that!
Try the plastic plugs for the scuttle screws, the seals on the back are as useful as a chocolate teapot. There are a few of them sitting over the hevac intakes. I had water in both sides for a couple of years, replaced and sealed them all with silly cone, havnt had water in for nearly 2 years now
 
Glad it's not just me!! I'm not sure what you mean though.. the covers for the screws that bolt the plastic cover to the bulk head at the bottom of the screen? Seal them up and should be sorted?
 
They are square plugs/nuts (AWR 1675) that the screws holding the air intake plenum screw into. If you remove the plenum cover then pull them out and you will see thin gaskets these perish. I bought a pile of new plugs/inserts but put a smear of silicone instead of the gasket. When I refitted the plenum grill (replace the foam at the same time) I dabbed a bit of silicone on the screw. Although the plastic plugs have a blind hole I had found a couple that had split. Easy fix and worked 100% for me.
If you replace the foam mesh on the intake take a look at datateks solution with perforated ally, I am going to do that next time!

Thanks! That makes sense!!
To take the plastic off from under the wiper arms, does the trim front the bottom of the screen have to come off? I've not got RAVE without hours of work
 
Yep, some of the screws are underneath it.
The main leak culprits are the fixings over the pollen filter openings, although I replaced/sealed them all to make sure.
Be careful with the lower windscreen finisher removal, use a flat trim removal blade, the little white plastic clips for it are obsolete, I think I bought the last stock from Belgium
 
Common cause on many cars is the weather sheet that should be attached to the inner side of the door - as in between the door card & the door itself. Sometimes missing or damaged.
These can be plastic sheet usually fixed with a sticky plasticine type material or preshaped items & cover the apertures in the door.
Rain runs down the outside of the car windows & into the door where it drips off the bottom of the window. It SHOULD then run down & out of the drains in the bottom of the door BUT if the sheets are missing it can drip onto the back of the door card & then runs down the door card onto the carpet.
Can affect rear doors as well.
The sticky plasticine is this: https://www.ebay.co.uk/i/362775850164?chn=ps
 
Cheers both
It's definitely under the screen/pollen filters because the filter is wet and it drips down the accelerator pedal

Not a job for now, guess what.. is raining!!
 
Clean out the drains one at either end of scuttle panel. Cannot be seen until pollen filter boxes are removed.
 
+1 on wammers comment, I did that when looking into my wet floors. A job worth doing but after I reassembled everything it still leaked, that’s when I stumbled onto the leaking plenum nuts, a very tiny piece causing a very big PIA but sooo easy to fix!
 
Thanks. I've got no cover and looks like it's going to take more than an hour so it's going to have to wait until a slightly dry day. Until then I've got a bailing bucket!
 
The plastic trim at the base of the windscreen can, with care, be slid off from one end, then it doesn't break the fastenings. You have to remove the A post trim to do it. coating all the heads of the screws on the valence with silicone cure rain water leaks on mine. I have also replaced the foam on the heater air intake with perforated metal, the foam doesn't last long in the sun here.
 
"The plastic trim at the base of the windscreen can, with care, be slid off from one end"

There is one screw holding it in
 
Yours must be different to mine then, no screw, just the clips. Luckily I have spare clips so I just used my trim tools to pry up the trim although I never damaged any, I got replacements due to an earlier windscreen replacement that had been bodged and loads were missing.
 
Just a thought but have you checked the AC drains underneath, my passenger side carpet was wet a few years ago. Cleared out the drains getting an arm full of black wet gunk in the process but cured the issue. Took less then 5 mins, raised the suspension to wade height and put two wheels on the kerb and crawled underneath with a bit of wire coat hanger.
 
I would agree that is worth doing but I think kermit said his pollen filters were wet so I would say the water is coming in from the top. Might have a bit of each though so still worthwhile cleaning the tubes.
