Well...my driver's side anyway...But seriously the door was shut all the way, the window was closed, sunroof was closed (and obviously sealing as no seats are wet) just the driver's floor is soaked and has a big puddle...Help me out here where should I look from here? thanks in advanced for any help

 

Look- all these units have drain plugs & holes that will whip away the water,but only if you keep them clear! Start looking at the vents! Clear all debris,then look into the windshield vent tubes as well! This is unfortunatlely a common Blazer issue. Search this site!More problematic in WA/OR/MN/WI-New England-or with the live oaks in the Carolinas!
