My heater is wofine, and there is no coolant leaking inside the Jeep. There is also no coolant leaking from the heater hoses attached to the heater core. Any help will be much appreciated.
I think that is a drain tube for the tray that is
under the AC and heater cores . It keeps condinsation from the AC from dripping inside and making a wet mess . Sounds like you have a leak started inside the heater box . My 05 drops water out of there constantly because of the humidity in this area during the summer when I have the AC on.
