HEAT IN NOT WORKING

2002 Jeep Liberty • 4WD Automatic • 160,000 miles

My 2002 Jeep Liberty had the radiator replaced about 153,000 miles. Since then, I have had trouble with my heat. It only gets lukewarm. They flushed the radiator and for a short time there was some heat, but now with the cold, not much is happening. What is the potential problem.

It sounds like the heater core could be partially plugged. The engine is probably contaminated too so it will get right back into the heater core unless you get the whole system flushed thoroughly. You may end up have to replace the heater cores but make sure the engine is cleaned out first.
