Recently with our hot weather we had issues with no air . So I charged the system with freon . It worked great for about 10 15 minutes. So quit and went ton to other issues. Weather started cold in the morning so my daughter brought the car back and said there is no heat. So I checked the car over . Now the air won't shutoff. Doesn't matter where the controls are set the air won't shut off. So we are at loss here and wondering if the control panel is bad ? is there any way to check this ? We had some rodent issues and thought maybe they did something ?
