Wet Windscreen - now erratic electrics

I've had all the various drain mods done - and so after finally getting a dry car - my windscreen every morning is completely soaking - as wet as it could be. No other windows suffer from this. And now the electrics seem intermittently dodgy - speedo, trip computer, fan, wipers cutting in and out in wet weather.

Your help would be much appreciated
