Not getting heat in cab

[Paul Scagliarini]

I am not getting heat into the cab. I have flushed the entire system, back walked the heater coil, checked that the door is opening at the fire wall,(it is), i do not have water in the cab or under the Jeep (in case, coil was cracked),I don’t have any more ideas?? Any body?

Have you felt the lines to the heater core going into the firewall to see if they are warm / hot when the engine is up to operating temp?

Couple thoughts, heater blend door or thermostat or even loose radiator cap causing pressure loss?

x2, check if your heater lines under the hood are warm when the engine is up to temp.
