how to avoid when rainin the water comes to the windshield and i cant see.

Hard to understand your question, but is the water your talking about, coming through the windshield seal onto the inside of the window? Or is the windshield fogging up?

if it it because the wipers arnt doing there job and smearing then go to the parts store or walmart and get a bottle of rain-x take it and apply it to your windshield and the rain will bead rather then stick. I use rain-x window wash and most times when it rain I can drive with out my wipers. it is awesome stuff. if it is fogging inside the window put on the defrost and flip down your visors to give extra heat to the window. \

It needs a silicon re-seal. Go to a windshield service & ask for an estimate. Don't do this yourself you'll make it worse & or break the windshield. Use pro's.

In the Hummer H3 when you hit puddles water hits The windshield, in other cars it doesn't happen.
