Usually anytime gages or lights act funny meaning they are just not going on or off which would be a powerloss, clean and simple. When you have bad or missing ground wire connections, what you get are under-powered dash lights, head lights, parking lights, and gages that look like theyre at the disco dancing to the wrong beat. This means that the components w/ bad grounds have to ground through different methods i.e... through metal chassis contact or worst of all grounding through a circuit that its not supposed to. That is why you have several indictions whichever circuit has a bad ground it is affecting the nearest circuit by grounding through it which scrambles and fights the energy in the other circuit creating your haywire symptoms. Best thing to do is identify your ground circuits and make sure the connections are good. Sometimes adding extra grounds could be your only solution to what can become a big headache. You'll need a wiring schematic and some basic knowledge of how electricity works. I suggest first some elematary reading on simple ciruits and electrical trouble-shooting before attemping repairs, This stuff is in most vehicle repair manuals,but for the most part bad connections are visible once you find the start and end of the circuit it can be pretty obvious. loose screw or bolt, loose terminal connection, or a hard overheated wire that acts more like resistor (like a dam restricting flow of electrons). Electrons flow like water, kink the pipe and u get less water same with electricity. Hope this helps to get You started on becoming aleast a little more knowledgeable when dealing with electrical issues. Tired connections and wiring are always an issue in older vehicles. Learning how to remedy simple wiring problmes is a must. Unless your vehicle has had electrical fires or severe short circuits what you are dealing with are fatigue induced problems. Age in another word.

How do you diagnose and fix the speedometer that only works intermittently on a 1996 Nissan truck?

Hi There, On my 1995 Nissan Pick-up, The speedometer as well as the tachometer would intermittenly stop working. Sometimes one would work then the other would stop working, sometimes both stopped working at the same time. I never knew when it would happen. Then, at 90,000 miles, the Check Engine light came on and everything worked GREAT. It turns out that the wire that sets off the Check Engine light was shroting out causing the problems. It was fixed today for a cost of $160.65. It worked for me, I hope that it works for you. Good Luck!

What part needs to be replaced for a 1989 Nissan Sentra when the odometer and speedometer are not working?

Most of the time, the speedometer cable breaks, and you replace it. The best way to find out, is to unscrew it from the transmission, and see if you can pull the cable out from the casing. If it checks out to be good, then it will be the drive gear inside the transmission, or the speedometer itself.


Why will the speedo work on a 1996 Nissan 200sx but the trip and odometer will not?

The odometer runs on the same electronic gear driven sensor as the speedometer so if the speedometer is working and the odometer is not the problem is in the "Speed head" (speedometer unit in the dash). Mine and several others I have seen break at about 40,000 and will need replacing.


What could cause speedometer problems in a 1996 Nissan Pathfinder?
