Passenger footwell wet with water

Afternoon All,
I have an issue with water entering the passenger footwell (RHD) of my P38. I did do a search a few weeks ago and found an issue with the Pollen Filter covers. The car was serviced and so the filters (which the passenger one was found to be wet) and covers were replaced and sealed with a rubber silicone. At this time the carpet had dried out, we cleared the air conditioning and sunroof drains which were clear and we even replaced the plenum filter with a mesh backing.
The last few days we have had a spot of rain and have noticed the windows misting up again, I have just been out to look at the carpet and again it is wet. Excluding the pollen filters is there any way the water could be getting back in? I ran a google search and someone said something about a hole above the pollen filter covers but I cannot find any images/more information on it.
Below is an image of where the carpet is most damp (please excuse the dirty carpets).

Thanks in advance.
 
Does it smell off coolant? It's not just the pollen filter covers that want sealing, the actual housing where it bolts to the bulkhead can leak, it did on mine. Also the pollen filter drains get blocked.
 
It does not smell of coolant, just water. The pollen filter covers have already been sealed and the drains have been cleared (they were already clear). I will check the housing in the morning. Thanks.
 
It is not the pollen filter drains it is the air con drains you want to look at.

Underneath the car - each side of the gearbox, you will see a rubber grommet in the chassis housing/floorpan, I use a nice piece of heavy duty nylon strimmer cable, and stuff that up each grommet - you will get wet! Usually when mine block, about 2lts of water comes out...

Do both, because even the drivers side blockage causes water to drip (exactly where your photo shows) into the passenger floor pan.

Good luck

He said the aircon drains have been done:)

.....I can find nothing in my owners manual about not working below 5C, that refrigerant should work down to well below 5C, must Google the refrigerant.

Have to say I have just looked through RAVE and can't see the 5degC thing....but I am almost 99% sure I have read it .....

Also the system won't work below 5degC to prevent the Evap from freezing....

The system has a logic circuit built in to compensate for if the vehicle is standstill, moving etc...so the HEVAC ECU can compensate for 'odd' ambient temp readings...

Hard to read, but I see nothing about it not operating below 5C, only limits to rate of temperature change and compensation for under bonnet temperatures.:)

The Evap won't freeze on a modern system as the heater matrix is always hot when running. Certainly the aircon will not operate for that very reason until the heater temperature is adequate.:):)
The 5C thing is bandied about a lot, I can see nothing that confirms it. Older refrigerants were problematic at low temperatures as were older heater designs.

The speed with which mine demists all windows in the ****ing rain once the engine is hot confirms that it's working even at 0C. The windows in the Trannie by comparison are impossible to keep clear in wet weather.:):)

Think I'll have to admit defeat as I can't reference it to back up my arguement...:eek:

As for demisting...in this weather we have been having..I don't run A/C and don't have any issues with misted windows....but then again (fingers crossed) I don't have any leaks....plus I rarely let the temp in my car get above 16 on the dial as I prefer it cooler....no issues with misting even with a screen covered in snow/ice/frost!

The aircon is smart enough to operate on it's own under certain conditions if I understand it correctly.
The aircon will fail more quickly if not used and it makes the best part of bugger all difference to fuel consumption on such a big heavy car.
Cool air holds less water so if the temperature differential across the glass is lower you will have less of a problem. On a non aircon car, it is normal to apply heat as the hot air will absorb more moisture.
My car is dry except when I get in soaking wet, without aircon, misting is almost inevitable and we have had so much rain the last few months I'm considering building an Ark:rolleyes:

True I admit the system is 'smart' enough to apply conditioned air as necessary....I do run it for half haur every couple of weeks to keep the oil circulating and lubing the O Rings to prevent them from drying out....

With regards to my original post...it is doubtful the 'smart' system will run the A/C long enough to build up an amount of condensate to soak the carpets considering the current weather, in my eyes.....

As for MPG, Admittedly the difference is minimal, around 0.5mpg by my calcs (I am sad and log my MPG on my iPhone and on fuelly....:eek:
 
Ant and Kieth shush a minute :) this bloke still got wet carpet... Took me months to sus this. If all else fails there is a screw that goes through the plastic facia directly above the pollen filter cover, which if not sealed will leak rain water directly into the duct by the bucket full. I have pics and even a bloody video of water pouring in here but on my other pc. So check and overseal with silicone sealant.

Talking about the air con. I wonder what genius at Land Rover decided that when it's switched off the red light is on and when it's on, the light is off? :D

I said it would dry the carpets if used (and the drains are clear). Keeping the insides of a Rangie dry is of the utmost importance with all the badly sited connectors and electronics. You would be surprised at the amount of condensate build up if the drains are blocked, in humid conditions I would reckon on up to half a litre an hour, plenty to soak the carpets when there is an overflow.
