You probably have a plugged drain hose for the blower motor/cowl. You can fix this yourself. Open your hood and look on the firewall on the passenger side, behind the engine. You'll see the drain hose coming out of the firewall and pointing down. It pulls out kinda like a grommet. Pull it out and unclog it. Installation is reverse of removal. The hose isn't cut that clean so at a glance it may look like you broke it but look closer and you'll see that it was molded that way.
