i have a 2004 QX56 that I have had for many of years with no issues…I tried to start it with no avail so I replaced the battery…no luck! Had the starter checked and it was fine….I have noticed that the carpet in front is VERY wet and a rusty drip mark running down the driver's side dashboard…I have had the windshield replaced a few years back after a branch shattered it but have never noticed any leakage…It has been too cold to do anything thus far as we are in Ohio but I need to address this as I need to sell to keep boys in their family home…(It is not the primary vehicle as I usually drive my truck as it is needed for my business (although not nearly as nice). We are a "do it yourself" type family as it is a financial necessity, plus I try to keep my boys educating themselves in these types of things…but is this an unachievable quest? Any insight or suggestions of any type would be greatly appreciated! Thx in advance, Cindy
