if your vehicle lights are working all the fuses will be good. follow the cable from the towing socket on your vehicle , it will most likely go behind one of the rear lights to connect into your cars system,
check your tester where the cables join and you should find the problem. hope this helps.

THERE SHOULD BE SEPARATE FUSES FOR THE TRAILER WIRES. HAVE YOU LOOKED UNDER THE STEERING COLUMN FOR THEM? IF YOU HAVE AND THEY CHECK OUT OKAY, THEN CHECK THE WHITE WIRE ON THE TRAILER PLUG, IT IS THE ONE THAT IS EXPOSED ON THE TRAILER PLUG. IT IS THE GROUND FOR ALL THE TRAILER LIGHTS AND THE MOST IMPORTANT OF ALL THE WIRES. SEE IF THE TRAILER HAS A GOOD CLEAN GROUND AS WELL(WHITE WIRE). HOPE THIS HELPS. PLEASE KEEP ME POSTED. THANKS FOR AN HONEST RATING AND FOR USING FIX-YA. GOOD LUCK

I can only assume your not the orignal owner/purchaser of this '99 Explorer, so im gonna say no if it doesnt have a factory trailer hitch and towing package. did you have an after market hitch installed on this truck? if not, please dont tell me you plan to use the "cheesy" factory drilled hole in the rear bumper (near/below the license plate area)? BAD IDEA if thats the case, the bumper brackets cant handle much of a load at all, bad idea for them to even put that stupid hole there to begin with. Also, if you see there isnt a "factory" harness, you can go to your local auto parts store and pick 1 up designed specifically for that vehicle within a range of model years sharing that same platform, eg. 1997-2001 model years may all use the same harness set. let me know how it turns out and if this even helped you in any way. Good luck.

If it is a factory trailer package then there are fuses for the left turn signal and the right turn signal for the trailer connector. Check your owners manual for the location of these two fuses.
