this is a random issue. the dash lights and radio lights/climate control lights all seem to turn off randomly when driving. it seems to happen only at night, when the headlights are turned on. if i play with the light switch they will flicker on and off but aren't really staying. also, at night, the interior lights won't stay on when i open the doors. (when head lights on) but after they turn off, if i use the key fob to unlock the door the interiors work fine. just wondering if anyone is having such gremlins. i'm thinking i might replace the battery anyways as its 7 years old but i don't think this is the issue. truck also runs just fine regardless of the lights being on or off, and it will still shift into 4wd as well (donno if that would be related) all help appreciated thanks!
