Help with electrical problem
2002 Ram, 4.7
Yesterday, I pulled into a parking lot and my dashboard lighting, gauges, horn, turn signals, hazards and wipers went completely dead. The truck continued to run perfectly fine, though. Appears to me to be an electrical problem. But I have no clue what's going on, and wouldn't know where to even begin looking.
I've had the truck for 2 years. No recent modifications have been done. After it happened, I got home and disconnected the negative from the battery. It seemed to me that maybe it was a temporary glitch and the disconnection would reset itself. I left it off for about an hour or so, and everything went back to normal.
This morning its happened again. Only this time the head and tail lights are also dead. The power windows function fine, along with the cigarette lighter and radio. The negative's been disconnected for a few hours, and no change.
Any help is appreciated. Thanks.
