Peterbilt 379: I have a 1998 379 Pete The air conditioner doesnt

Customer Question

I have a 1998 379 Pete The air conditioner doesnt drip out the drain tube until I turn off the blower fan and AC switch then the condensation will pour out the drain tube as soon as I turn everything back on it stops again and stays in the heater/AC box eventually it will back up to the point it runs out on the floor. Any ideas ????
