If you take the lower dash panel off you should be able to see the joint of the heater matrix and the pipes to see if the o rings are leaking.

If the engine cooling system is not losing water, then it could be condensate from the aircon. The drain tubes get blocked

There is a good write up on Range Rovers on the o ring replacment.

However a couple of tips from when I did mine, tigten the screw on so there is still a little movement in the plate and then squezze it togther with some long noze ppliers to get it all lined up and then do the final few truns.

I also put a a nut on the pack of the plate as i could feel the thread in the cast alloy plate starting to go, in fact the nut means you and get it nice and tight with a spanner on the back of it.

i always change the phillips screw for a small nut head bolt then you can use a socket and ratchet makes a good tight fixing though have also come across one with stud lock and i had to remove the dash as the screw rounded off! and the bracket snapped

He thanks for the tips, how long does it take just to change the o rings.

I think it is just the o rings that are leaking as it only seem to be damp on the drivers side, plus it doesn't mist thescreen up when running like a old car i used to have when the matrix went.

Is it a common thing on a p38 for the matrix to give up, My mate has just changed his on his classic.
