2006 Dodge Caravan Replacing washer fluid hoses

Hey guys!

I've lost pressure in both the front washerfluid sprayers. When I spray I've noticed a fountain of fluid coming out of the grill between the hood and the windshield that houses the supply hose. I'm guessing that the line has probably cracked due to very cold temperatures. I've located and removed the six screws that hold the grill in place. I've removed the bolt that holds the wiper blade in place but can't seem to get the wiper arm off so I can remove the grill to access the crack in the line, is there a trick to this? Also, I've been told that there may be cliips locking it in place. Any advice on removing this grill?

Thanks!
