Yet another "my floor is wet from the A/C thread." I just had the A/C in my truck recharged. It's been non-functional for 6 years. I've been using it and I have water running out the floor duct on the passenger side. I figured the drain was just plugged up form lack of use. I blew air back through it and attached a piece of rubber hose to it to extend it away from the firewall. I've heard that sometimes the water can run back along the bottom of the factory drain line and drip on the floor. Well, still no change. The factory drain has water dripping from it, but there is still water leaking out the floor duct. What do I do now?
