Heater problem 6 cyl Four Wheel Drive Automatic 120, 00 miles

I have noticed recently the heater on my Liberty is not working correctly. When driving, the heater works better but when idling such as at a stop light or in a drive through line the air the heater is blowing becomes cooler.

What do I check or where do I start? Thanks!

Hello,

It sounds like the coolant level is low or the heater core has blockage internally. Here is a video and a guide to help you run some simple checks to fix the problem.
