Hey guys, The warm air from my heater in my Glanza V tends to fog up the windscreen no matter what the weather is outside, and even after then it takes ages to clear! Do any of you guys know what the problem is? We've heard it could be the cabin filter or something to do with the air con - which has been removed anyway! If you could help I'd be forever thankful as I kinda need warmth now it's getting colder! Thank you in advance!!
