Lick the window ! Lol probably best not to try that while you're driving,
apart from the funny looks you'd get it'd probably be a bit dangerous!

Maybe running a finger through the moisture on the screen then tasting the
tip of your finger would be a better/easier option!

But you're right about what you say about leaking heater matrix.

Also using "recirculate" is a bad idea, especially if you've been using the
aircon. Recirculate simply blows the moist air in the car (and any moisture
that has collected on the heat exchanger if you've been using the aircon)
onto the windscreen making it steam up, better to put it onto the fresh air
setting. Or if that doesnt work you'll just have to switch off the blower
and open the windows, and get the leak or faulty recirculate/fresh air knob
