Try turning the hazard switch on and off several times real fast. A bad connection in the combination switch can cause that problem. Check your brake light switch to make sure it has current.
Hi,
If I understand you right based on your post/description, the signal lights would still turn on even if any or both of the flasher relays are removed. Should this be the case, then the signal lights are not getting the power from the flasher relays but from the brake light circuit.
Perhaps your concern is not with any of the flasher, but simply missing or loose ground more particularly with the rear lights. Perhaps you could try determining which of the wires for the brake lights and signal lights (as they come out of the light assembly) would be ground . A test and even possibly a temporary workaround is to hard wire a second ground connection from the determined ground wire of the lights and attach it to any conveniently located bolt or screw to the body. it may be to your advantage to do this on all the rear lights assembly.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
SOURCE: signal lights and brake lights stopped working
the multifunction switch (turn signal switch) is a major cuase of this. your high mount stop lamp wire is run through the switch.
SOURCE: 1999 f150 turn signals and brake lights out. High mast still work
The signal lights work through a relay but the brake lights work through the signal switch, if both are out I think you'll find the problem is the signal switch.

Check the wires at the connection point and follow them back up to the tail light look for any disconnected wires or grounds. Good luck.
