My trooper is 09 behind the d/s i black metal black box the protects the ecm nxt to that there is a black plastic box which holds fuses even if the fuses are good u might wanna in bolt it and look at the back side for corrosion and burnt wires I think there are relays there to. On mine under the right side dash I have a black plastic box with fuses and relays I would check them as well. Does your hazard lights work normally
