Ranger brake lights stopped working when trailer was hooked up, still don't work
I have a trailer I use with other vehicles with no problem. Just got the 99 Ranger and tested hooking up the trailer to see if lights worked. (To test Ranger harness)
1. Blinker left and right - worked.
2. Tapped brake lights Ė worked.
3. Running lights Ė worked.
4. Flasher lights Ė worked.
Went back to brake lights. They donít work. Then noticed the Ranger brake lights arenít working. In short all lights work on trailer and on Ranger work except brake lights on both. So I unplug trailer. Ranger brake lights still donít work. There is some converter on the ranger harness from a round plug to the standard, so I unplug it. Same thing. I check fuses. All fuses seem to be flash and brake together on same fuse, but all fuses that seem to relate are good. I take out the brake/flash bulb. Both filaments appear good. A brand new bulb was put in. Same thing, turn filament in the bulb works, but brake in same bulb does not.
So the brake lights worked for the tap at the very beginning on trailer and always worked on Ranger. But not anymore.
