  1. 2011 chevy 1500 lt Heater malfunction,, Temp goes warm and code while running from both sides of dash and body codes b0413-02 b0423-02 b3779-02 b022802 b0423-04 b3779-04 the first time I pulled codes and after clearing system b0423-4 came back. The system will work normal after I pull fuse for module for about 2-5 minutes and then temp goes cold and warm until pull fuse again. Need some help
