hey there hew here to this forum. i have a 98 explorer 4 door with the v-8, the headlights will come on when i turn the vehicle on to go to work in the morning, (the switch is off), they stay on till they time out when i get to work. When i leave work at 330 in the afternoon the DO NOT come on. any idea's on this, I have replaced the headlight switch, thinking about the dimmer switch but not sure if that will fix it.
