Cars Q&A

I have 02 months old i 10 hyundai Sportz model.Yesterday I drived it in Uttrakhand( Roorkee to Bareilly) at 4 A.M. I faced a lot of problem with respect to its wind screen. Snow like vapour are getting(condensed) inside and over it. Even it is coming again and again after every 05 minutes. I tried with different modes like with or without AC, opened the window to normalise temerature,used wiper but no heal. During return next day, there was heavy rain. I again faced the similar difficulties.No clear front vision to enable me to drive even at 40 km/hour.When opposite side vehicle throw long beam then it got worsed as rainbow like forming on screen. I am driving Fiat, Maruti since last 15 years , no such problem I have faced earlier. Please advise.
