SL/R230: How do I remove rain box beside battery&ID Coolant Leak Hose?




How do I get this rain box out? It is stuck at a windshield pan drain spout. You can kinda' see the drain spout location by the round mirror. The box is behind the battery at the firewall. See pics. Is there a usual suspect hose behind the rain box that leaks coolant? The windshield drain pan has a spout that is poking down onto the edge of the box. It kinda' looks like I have to remove the windshield wipers. Is there a seal at the drain pan and windshield
?
