00 Grand Cherokee slow coolant leak, low heat
No/very low ac or heat flow from side vents. The highest
speed setting is the only one that works. Defrost and center
vents blow but only on highest setting. Replaced water
pump and thermostat 2 weeks ago. Looses coolant slowly
and reservoir tank stays full, so I top off radiator. Can't pin
point the leak, blows warm air when it's set on heat. AC was
acting the same in summer time, never got cold after I
recharged it. I was thinking about flushing heater core, not
sure if it could be a combination of issues but don't want to
replace heater core unless I had to.
