The headlights on my 1997 Dodge Ram 1500 are causing problems. The headlights have been going out just about every morning for about 10 seconds. About fifteen miles into my commute. Then they come back on and seem fine. The other day when it was real cold, they wouldn’t come on at all. The next day they were fine.
This is a classic description of an intermittent open connection. This can be caused by a loose connection, rusty or corroded connection or a break in the wiring harness. Looking at the wiring diagram I can see there is no relay for the headlights and should make it easier to narrow down. Start by checking the connections. You may also want to perform the “wiggle test” on the wiring.
