Water seeping through passenger side of vehicle and soaking mat and floor. AC works fine while driving straight or right turns but sounds like water flowing to passenger side when taking left turn. Is this something I can do myself of is it major and needs to be taken to shop?
The drain tube is plugged. Look under the hood on the passenger side of the firewall for a rubber tube hanging down, typically about 4" long. Squeeze the end to open it up to see if anything will dislodge and water comes pouring out. It not, you'll have to remove that tube and stick something into the drain to clear it.
