I have a 1995 LS 3.0 liter that recently started blowing the brake light and running light fuses.. Sometimes they will last for hours and other times instantly... I replaced the brake relay, headlight switch, and checked every possible connection. Does anyone have a solution?

 

Problem solved... I replaced the 2 black relays under the hood that were clicking when I switched the lights on... No more brake light or tail light fuse blowing issues.

 

good job, this gives us more info for reference for others who may have similar problems in the future.
