Sorry to hear about your issues which obviously need dealer attention. Apologies if you already know this, but keeping the air con / climate control on all year round will help to minimise condensation within the cabin and will clear condensation from your windscreen in a fraction of the time compared to when it’s off.
I only mention this as it amazes me how many people think that air con / climate control is just designed to keep a car interior cool in the summer and don’t appreciate that it should be left on all year round, with just the temperature adjusted. Aside from the fact that if these systems are turned off all winter the seals can dry out and perish (so the coolant leaks out), these systems reduce humidity in the cabin which, in addition to stopping condensation, reduces driver fatigue.
