This sounds like the common fault of the control head/control in the dash itself.It can fail internally to where no display comes up with it needing to be replaced.What has to be done is to have the fault codes read out/checked with a compatible scan tool or computer plugged into your vehicle that can read all computers in your model.Once this is done any codes set then need to be diagnosed to then help to locate and repair this issue here.
