Ok im a bit fed up now with this prob

its a skoda favorit ( I know its fuckin shit scrap etc ) so keep your comments to yourself pls, as its my daily!
ive been seeing water on the floor mainly, coming from under the dash. we sealed the windscreen so its not there, can there be a problem near the mudguard or battery? and when im driving through water, theres water coming from the floor! can it be that theres not a mudguard cover!
many thankx lads, cause its a nightmare!
