So went to pick some pizza last night everything fine on the way there, coming back had no headlights (low or Hi beam), Dash lights and marker lights were on.
Switch was dead (did nothing)..marker lights would not turn off and headlights would not come on?
Even shutting truck off and taking key out marker lights would not turn off had to disconnect the battery to get them to turn off.
Hooked up the battery again today to try to see if I could figure anything out....all lights were off until I turned the switch...then same thing...no headlights and marker lights would no turn off...

Thinking it is a relay stuck, but cant figure out which one? there is no relay for the headlights?

Can anyone help?

Oh, also I have had my right rear turn and brake out (not the bulb)...would that be fuse #19?

Thanks
