I've seen a lot of posts for problems with the 2006-07 models leaky water deflector but can't seem to find anything on the later models, mine is a 2010. It's definitely rain related. It rained hard here last night and the passenger side floor is drenched. I need to replace the blower motor resister but don't want to do it until I've solved the water leak. I'm about to remove the cowl and investigate. Any feedback would be greatly appreciated.

 

Windshield seal.
Sunroof seal or drains.
Door wiring pass-thru grommet.
Door weatherstrip.

 

Did the fan start running on high ONLY; that indicates a bad resistor.
AC drain clogged. The AC runs in defrost mode with no warning light.

 

Leaf or other debris built up in the cowl area.

 

After pulling off the cowl, the drain on the passenger side was completely clogged (the driver's side was getting there), the oval drain was partially plugged, and the seal around the AC drain tube was deteriorating. Cleaned out the debris and sealed around the drain tube.

 

I had completely forgotten those drains!
