Have 2007 pontiac g5. Noticed floor on passenger side damp. Went and was running ac on high due to hot weather and when came home app. 90 minutes late the was more water on passenger side floor. Carpet very wet

Make sure the drain tube from the evaporator tray is not plugged.. Should see a small tube through the floor under the inside unit. If you don't see water dripping out under the car when AC is running, the drain is plugged.

Run a large pipe cleaner or wire up the A/C evaporator drain tube, which is located along the firewall on the passenger's side of the car. Be prepared for water to come gushing out.
