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. 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. But, this morning its happened again.

Any help is appreciated. Thanks.

prehaps a relay is going
if a relay heats up to much it will cut off.
look in the fuse box and see which one
works for the cluster panel directional etc.
also i think the drivers manual shows where
its located to.Good Luck.

 

my 2001 did this once already..the dealership replaced the entire insturment cluster. worked well up until about a month ago now doing it again. I have pulled the fuses and pulled the negative cable has not changed. I am thinking it is the ECM.
