So more fun with the grenadier 
It rained here yesterday, 18 hours is of steady but not hard rain. Driving to work I hear water in the cabin, ok fun fun.
I’m at home now and well yep there’s water, it’s contained to the front passenger footwell. Pulled the rugs the plugs, drained the water. Heater in cabin to dry it out. Rubber floors are soaked weight 10lb so I’m drying them out with a heater in a small bathroom. Checked door and window no leak, checked for any reason for water, cabin filter is dry. But then decided to open hood and pop off cabin filter inlet for a look and I see this situation. Inlet door is half open and I can see clear into the truck, or if it’s in recirculate same deal. Now there’s a big funnel lip around the air intake so if water got in it would have been while driving? Or so much water it flooded over and in?
