Hope someone can help me. I have a 2009 V70 R Design. After alot of heavy rain I am hearing water running from side to side when turning below my dash board. There most be a channel blocked. Does anyone know where I should look?

 

Not on something that new. Maybe someone else will come in and help.

 

What is wrong with going to the dealer for this particular issue. Should fall under warranty, am I right?

If you are saying you hear water within the dash itself, I would suspect a leaky windshield since it only occurs under heavy rain. If it happens in the footwell, then possibly a clogged sunroof drain. But these are just guesses.

 

This is a common problem with ALL cars. It happened to my 1972 Gremlin "X", all the way up to my 2007 Mustang GT, and it usually shows itself after a lot of wet weather and air conditioner use.

The drain hole(s) for your air con box under the dash have sludgy bug filled crap in 'em. This is preventing the condensate water from draining out. Get a coat hanger, gun barrel cleaning brush, or sumthin', crawl up under the car and look for a small hose or hole coming out of the front floor pan/firewall near the foot well area. Stick your cleaning tool up in there and see what you can pull out. Don't have your face under the hole when you do this.

 

The air box inlet is in the passenger side under the cowel, you need to replace the foam seal and I took and extra step and put "dum dum" around the air box trumpet to keep excessive rain water to over flowing the edge and leaking through my new foam seal.

IT will also stop that awful whistle from your passenger side when driving at highway speed.
