Hi, I have a 2005 Jeep Grand Cherokee Laredo and all it does right now is blow cold air when the heater is on. It worked fine 2 days ago and all of a sudden it stopped working. The two hoses going into the firewall are both hot which should mean the fluid is circulating through the core. I have no leaks under the dash or smell. I took the glove box off and the fan control ( blend door ) is opening and closing properly and there is fluid in the reservoir. Has anybody had this problem ? It seems to be the temp control but I have no idea where to look. Thanks for any help I can get on this.
My resistor went out on my jeep, 2005 jeep grand cherokee. Works only on high, and doesn't blow warm air. Easy fix. It's behind the glove box. The resistor is like a $15 part from cost less auto parts.
