Have recently found alot of water condensation on the inside of the front screen.Its not fogging like you often find on cars in winter but streams of water.Never had this before,any ideas?

 

You could try blowing your hooter

 

you have a water leak into the car somewhere this causes lots of water on the inner screen maybee its a water leak into the boot through the rear lights if not then you must search for it in the cabin area
hope this helps you
