Now the mornings have turned a bit nippy I find an old problem has returned. Thick condensation on the rear window. As in unusually thick, 10 minutes plus of the screen heater on and it's still not clear.
I've checked the carpets and interior of the car and they are all fine. No evidence of water leaks. After 3 years of owning the car I'm beginning to think it's just a "feature" as it has always done this. Does anyone else get this?
