How do I repair this problem

There is water leaking into the passanger side floor. It appears to be flowing from the Blower Motor ane Duct work under the dash. It really sloches out with a right turn.

I just bought this Seville SLS. Fine car, no doubt. Washer fluid pump doesn't pump. Could intake port be clogged, or is it a relay/pump issue?
