This has happened twice to me in the last couple of months, 2005 f-250 6.0 the display does not come on at all until I recrank the truck? Now my brothers truck is doing it. I have had electonic problems before with a 97 f-150 and the service department told me they would have to have it hooked up to their computer when it happens. I quess what I'm asking has anybody else had this happen to them and do you know if it leaves some kind of code for the ford place to see if I bring it to them with the ac still working?

 

PS. my brother truck is also a 05 f-250, with the both of us having this problem I fiqure it must be common. thanks in advance guys

Thanks I will try this the next time, and tell my brother this info also.

 

The head lamp trick worked on mine also. FWIW, since I got new batteries it has not happened. With the old batteries it happened about once per month. Coincidence?

 

Interesting...mabe the heat has got to my batteries. I'm going to take it in next week and see if ford can fix it while its still under warrenty.

 

Mine did the same thing. They replaces the head (control) unit under warranty.
