Question about Ford Ranger
Do they just turn on solid? If that is the the case, it needs a flasher relay. It is located up under the dash on the drivers side. If you purchase one at an auto parts store, you should be able to find it pretty easy. If they don't turn on at all, I would make sure the turn signal switch is plugged in all the way, and or doesn't have any pulled or broken wires going to it. Could be the turn signal switch its self.

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.
