Heat will not turn off!!
Ok I just bought a 99 Chrysler 300 and the heat only worked on high and then just went dead all together one day so we bought a blower motor resistor and replaced it and now the heat works and the temp controls all work but it will not turn off. The switch or faceplate works just fine i can change the temp and the setting and when I press the off button the screen turns off but the heat stays on. Any ideas what the problem could be
