2007 expedition. Remote start was working fine. Now nothing. No lights come on or horn doesn't honk when I push button. I tried locking the doors but nothing still. Replaced batteries in remote still nothing. Any step by step things to try. I'm not completely mechanic illiterate so I can manage some stuff. I'm learning. Just got this last year. So help me out fellas

 

Blown fuse or fuses?

 

Maybe unplug the truck battery for a minute to see if it will reboot something; you never know.
