Heater Core Replaced, Blower Motor Replaced, still see white smoke
Hello Jeep Forum,
Almost a year ago I noticed coolant leaking onto the floorboards of my XJ. Thanks to this forum we were able to remove the dash, replace the old and faulty heater core, and put the dash back in place. At the time when we replaced the heater core everything worked. A few months after we replaced the heater core, I turned on the defroster and white smoke came through the vents (didn't smell like coolant, it smelled like old ciagarette ashes). There was also no air coming through the vents. My logic was that the blower motor had burned up. The Jeep is a 97 Cherokee Sport 4.0. We replaced the blower motor today and the same white smoke is coming through the vents when I turn on the heat and I still do not have air coming through the vents. Can someone please let me know if there is something else I need to replace or do?
