I have a 2001 Infiniti QX4, last week while I was driving my dummy lights all started flicking and I started to smell like wires burning, when I checked the battery the negative was loose so I tightened it, I then realized that my blinkers on the cluster were blinking fast, I changed the flasher and the cluster signal and hazard worked good, I then noticed that none of my outside signal or hazards were not working, I checked all the bulbs all the fuses and there all good, what could it be I hate not having signal or hazard lights, I did not see any burnt wires.
Well you can easily have destroyed computer modules. When the cables loose that makes the circuits work harder which can easily fry computer modules make sure you haven't lost any fuses the fuse boxes everywhere check all the fuses first but if not I'm tired try the computer module you're going to have to hire a mechanic on that one
