    2008 Mack Pinnacle is leaking water on passenger floor when AC is on. It takes a hot minute even once I turn the ac off to quit leaking. It’s definitely water not antifreeze. When I get out of the truck you can see it leaking underneath so does that eliminate that the tube is not plugged ? The condensation is just insane under there. What could this be ?

    Drain in the heater box must be plugged. That’s the water that should be a puddle under the truck, not in the passenger footwell.
