My 98.5 has no heat or defrost at all. Put in a new heater core last summer & I have zero coolant loss. I'm assuming the next thing to check is the blend door but I can't see an actuator under my dash. I know some models were controlled by a cable but I can't find any definitive information as to which ones. One article I read says Dodge started using the actuator in 95 & another says 98 but that not all 98's have them. Can anyone give me the correct information? Also, is there anything I should check before I tear into the dash to try to fix it? If mine is cable operated how difficult of a fix am I looking at?
