421stang Posted October 26, 2021 Share Posted October 26, 2021 Ok, so I have a 1999 f350 v10. I keep popping the brake light fuse but it only pops with the key on engine running. It will not pop any other time. I have also popped the blinker/hazard fuse a couple times but that is rare. I have noticed that when ideling in park applying the brake the ideal will drop and then the fuse pops. Ideling with the blinker on the ideal is up and down with the blinker flash. All this happens even with the tail lights completely UN plugged and removed. I had a flaky vss at the dif that started at the same time but since replaced and no longer an issue. Any help would be greatly appreciated. Thanks everyone, 421stang Quote Link to comment Share on other sites More sharing options...
