Defroster puts out cold air doesn't Clair window .sometimes after 10min. It will warm up this happens all the time. And my back up camera some blacks out or projects upside down every other time I back up.

For the defroster issue, air temperature is often related to the climate control settings as well as the engine temperature. If the settings in the vehicle are working properly, it's possible the engine is not getting to operating temperature quickly enough, preventing warm air from starting fast enough. This will need to be tested. Regarding the back up camera, if it is a Ford factory camera, it could be a concern within the control unit causing it to black out or display upside down. Testing is required here also.
