2000 Jimmy Heat is always on
We have a 2000 Jimmy and the heat stays on all the time. Yes the heat control is turned to minimum.GM says that is a normal condition for the heater core to dissipate excess heat from the cooling system all the time, that is pure crap. I've owned 12 vehicles in my life time and only had one do that before, stuck control valve. Couldn't spot one in the engine compartment. Maybe GM is too lazy to check under the dash. Anyone had the same problem and get the run around from GM? Did you get it fixed?
