It seems to only happen after lifttruck sits for awhile. But when you go to start it , it won't crank over. And when you release the key to the wrong position. It says release washer button. Then if you wait while leaving the key on the LCD screen switches to temp and then you can crank it over and start it. The waiting time varies as little as 20 seconds or as long as a couple minutes. but it will not crank as long as it says release washer button. I have looked for loose connections, wiggled wires, and tapped on ECM. It seems to have a mind of its own.
