MK3 focus drivers side wet floor

[Voipboy]

Hi all,

So I have a problem with an annoying leak on a MK3 focus drivers side.

The front and rear carpets were wet, however since sealing the rear flaps and replacing the light cluster grommets the rear seems generally ok.

The front carpet is wet where the air vent to the rear seems to be gathering moisture - it's visible on the plastic housing and the carpet lining around the area also wet though I have to say almost feels a bit sticky to touch? I was concerned it may be coolant but the level is not changing so doesn't seem to be leaking.

Could this be the dreaded heater matrix or another issue unrelated? I've ruled out a leak from the bulkhead as the carpets are not wet at all under the pedals, however nor are they wet directly under the centre console on the drivers side which if it was a leak from the matrix I'd expect?

 

Any idea? I'll add some photos also...

 

Thanks
