From what you have described here this sounds like an internal electrical fault with the heater/ac control on the dash itself.I have seen this control fail in the past before and cause issues like this here needing replaced.With all that is occuring here this sounds like it needs replaced to correct this fault.If you have not had the fault codes checked using a scan tool that can communicate with all computers in your vehicle this needs done.Any codes set will need diagnosed to locate and repair the fault here.I suspect you will need to replace the control panel on the dash.
