I've been using the AC more and more now that the heat is finally here. I have yet to see any water dripping from underneath the truck while/after it's been on. Does anyone know where the drain is located at. Nothing leaking through on the inside, but I would imagine the system should be dripping something in 90 degree heat with high humidity. I've also been hearing a lot of gurgling/ the sound of water running gently while the system is on, especially while the compressor is running(no it's not the coolant system noises, go that fixed a while ago ) Hopefully someone can help on this.
