If you are having issues determining the location of your issue, I recommend using a circuit test, like # PTW2993, to check your wires. If you are sure, you don't have power after the fuses, I recommend checking the power side of the fuses first. If you have power coming in and not going out, you need to replace the fuses. If you have power going in and coming out, but don't have power at your trailer connector, then you will want to check your wires for visual damage and then use the circuit tester to determine where the wires have shorted and replace in those locations.

If you don't have power coming into the fuse box at those locations, check for relays needed. Your owner's manual should be a big help, but if you have exhausted those options, it may be time to take it to a mechanic.
