20019 F350. When temperature is around 0 degrees Celsius, and it is damp weather.
Every time I touch brakes display goes from “trailer connected” to “trailer disconnected “, even though there is no trailer connected. If temperatures get above +5, or, below -5 ( Celsius) the problem goes away. The blinker blinks fast when it says “trailer connected”.

Crawl under the truck and look for the harness that connects the plug in the bumper to the frame, disconnect it and clean it out, then get some water proof stuff for electrical and spray the two parts before plugging them back in. Sounds like there is corrosion in there.

the fast blink on your dash indicator is to alert you of a problem with trailer turn signals, since the truck thinks there is a trailer but can't see a load from the turn signals because there is no trailer the indicator hyper flashes

Take a look at your trailer plugs as well and see if they are corroded or not sealed. Check both on the hitch and the one in the bed if you have the 5th wheel prep package. These are easy to check.
