Hola,

The last couple days I been getting ~ 2-3 inches of water in the passenger side only. I tape the sunroof and clean the drain tube behind the heater core but the water just kept coming every time it rain. Today, I removed the cowl that covers the wiper motor and to my surprise just to the left of where the cabin filter is located there is a drain tube. I had ~ 4 inches of mud and leaves. The metal slopes the water towards this drain.

Next time you are replacing the cabin filter make sure to clean this drain.

I did this work on the 93/ 850 that mainly sits outside year round.
