Got a 2000 sterling. Problem Im having with it is that the headlights only seem to work when it’s warm out. Bought the truck last summer no problem. Cold temps this winter and the headlights,signal lights aren’t working when it’s cold. Bring it in the garage and let the truck warm up over night and no problem. Let it sit outside over night. Temps below freezing. Nothing. The lights in the dash when you hit the switch (key off or on) will light up automatically without functioning any of the controls (Dimmer light,signal lights) But nothing actually lights up in front of the truck. Brake lights and such are good. Anyone ever ran into this?
