For some reason I seem to be getting a build up of condensation after a while of driving that is isolated to around the area of the windscreen near to the air vent that blows onto the windscreen. I get this even on a warm good day?

Can't work out why this could be happening anyone any ideas?

Possibly a leaky heater matrix. Also check the ducting under the wing for damp 'n splits, think they have foam inside for sound deadening on late Mins.

maybe a slight water leak from the heater matrix. because the heater uses fresh air, even with the fan turned off, air still flows through the heater, and if its leaking (boiling hot water, so its as steam) then this will appear as condensation. You might not notice any coolant loss as it could be very slight.

Alternatively, if its like mine, water leaks in round the windscreen seal. if its a warm day, or using the heater, the area behind the dash gets warm so the evaporating water forms as condensation on the screen.

you can buy a product from the same people that make rainx .

you use it polish the inner windows and it stops them fogging up. Its called No Fog

Very handy stuff I used to use it in my MX5 as they were really bad a steaming up.

That is good stuff, i've used in on my crash helmet visor.

I used to coat the inside of the visor with slightly diluted washing up liquid. That seemed to help a lot with condensation.

Remember that you still will need to check to see if you have a leak somewhere. lol

Also Frost do a bean bag thingy that you put in your car to take the condensation out, every 3 months you bung it in the micro to recharge it.

here is a link to Anti Fog

Thank's everyone. This forum never ceases to amaze me at not only how helpful and knowledgeable everyone is but also how ready they are to share this. Makes a change these days. It's probably the nicest place on the net.

I think I will have to check the heater matrix as even on the hottest day this year it was steaming up and that of course is not logical.
