Jeep Information


Model:grand cherokee ltd



help I'm cold in canada! My jeep suddenly has no heat. The lines that go to the heater core are warm and with the blower fan off and you can feel heat inside the cabin on the passenger side under the dash but it only blows cold air with the heater fan on. I assume it has something to do with the digital heater controls not opening something? Any suggestions?

I am growing through the same problem.. I flushed heater core out with clr got a lil gunk out however it ended up being the vacuum line that controls the doors for a can heat. Not sure what exactly it is called though..
