Intermttent cluster failure
I have a 2021 F350 and recently I will get flashing codes on the dash (blind spot sensor blocked and pre collision) after I drive for about half hour or so. Then the windows do t work, heater, heated seats don’t work, and the lights on the control panel flash on and off. Radio works but you can’t use the buttons on the dash to control it. Also the screen freezes but doesn’t go blank. Happens not only when driving but also when the truck is sitting idling. Sensor? Loose wire? Ecm?

Here is the vin number.
It’s all the controls on the centre console tempetures controls, heated seats radio. You can control the radio from the steering wheel though. They work fine then the lights go out or flicker and the heat doesn’t blow seats turn off etc also windows don’t work.

Batteries need to be LOAD TESTED, not just voltage.
A good auto parts store or any auto repair shop can easily do it.
If it has dual batteries, you will need to disconnect one to get an accurate load test as they are interconnected.
A bad battery can screw up many things on these trucks, they are super sensitive to proper voltage and amperage.
Also, check the ground points.
And, if you want the Ford rep to look into a dealer repair solution for you, you will need to send them the truck info by a private message, not just posting it here.
