Large cars are prone to this cheapest thing to do is drive with windows down for a few mins.

Assuming that everything is working right, and you are still experiencing the problem, Kleeneze, Lakeland plastics and some auto shops sell something which could help:

de-misting fluid/wipes, which are a water reppellant liquid, and effects last about 6 weeks per application. (They are also sold for keeping bathroom mirrors from fogging up).

Check that your heater matrix isnt leaking, if it is it will be sending damp air into the car, which will mist up the windows severely

Turn your heater blower on
