2010 FFH with 130K miles in Virginia AC works great I have been noticing a damp carpet (and maybe a slight smell) in front passenger's footwell. Bottom of floormat when lifted up had condensation underneath, and carpet underneath was damp. I first thought this was occurring after rain, but I also thought it actually occurs after long road trips with AC on. For maybe 6 months now off and on dampness in that area. I just now pulled up/back carpet under glove box area. Had to remove plastic trim piece along bottom door edge seal area also (pulled up and wiggled free). Sound deadening cloth/under pad is soaked. Pool of water at base of footwell. Carpet underpad soaked all the way back to seat mount. Area is drying out now (I propped up carpet with plastic containers) in sun and directed fan as best I could. (I would prefer not to have to take the seats out ? ) This is a common problem on all cars (all makes) in that the AC condensate drain gets clogged up and water backs up into cabin. Also, gasket around drain through firewall may deteriorate and water drips back on drain pipe and through firewall. I searched internet for pics of AC drain. It should be on opposite side of condenser heater core plastic box low point. Some internet posts show a stub pipe coming out. Difficult to see on hybrid because ABS module is in way of view. Some have added a right angle elbow to direct condensate downward and silicone around firewall hole. Is there an easy way to get to drain and clean out? Anyone else had this problem? I even thought of cutting 1/2" hole on bottom of box on cabin side, and then seal with plug. I tried finding same topic on this site, but no luck.
