SOURCE: 1990 nissan hardbody only shifts into 4th and rev

Injt: From your description, it sounds serious. If you are describing a Nissan 5 speed transmission, here would be my best guess as to what has occurred. Prior to near total self destruction, these symptoms will show up when counter gear bearings have failed.
At first the transmission will just seem a little noisy, but you probably might not notice that the noise is not present in 4th.
As the bearings deteriorates, the countergear will slowly start dropping and the gears will no longer be running properly aligned.
The noise at that point would be quite obvious. You would hear it in all gears but 4th. With the car at a standstill in neutral with it running and the clutch pedal released to where the transmission is turning, it would sound like a bucket of rocks loose, rattling in the tunnel area of the car. When you depress the clutch in, the noise would disappear. The reason you could run it in 4th is because it is the only gear in which the input shaft and output shaft are locked solid with no relationship to the counter gear. The truck/car can be driven in 4th for this reason. (It doesn't need the counter gear)
Reverse gear is a large gear located at the very center of the transmission next to the Steel center section which you would see sandwiched between the front casing and the tail housing. It is not much more than 1"" thick. Because Reverse is right at that location, even though it does need the counter gear to transfer power, it is the only gear in the transmission which is "SPUR" cut and not helical cut. This design gives it a distinct advantage to operate in a misaligned state with greater spacing. It will still make quite a racket in reverse, but it will move. I am 99% sure that this is your problem. Should this be the case, the transmission has been run far too long to consider repairing. It would probably be scrap metal inside. Find a used one or get a re manufactured one.
I have found that the synthetic gear oils have worked well in our Nissan 300Z race cars we use for road racing. They have basically the same transmission. I am partial to Amsoil and Redline. Both have performed beyond expectations on the track.
I hope I have answered you question.

SOURCE: Gas gauge in the dash malfunctioning - 1990 Nissan Hardbody truck

It sounds like the float on the sending unit is sinking. Don't know what the float is made of, but over time, it will soak up gas and start to get heavy. This would cause your problem. I don't think it's the gauge, but if you want to test it, disconnect the wires at the tank. The gauge will either go to full or empty. If you ground the sending wire, the gauge should respond the opposite way it was. good luck

Parking lights plate lights taillights and shift indicator light went out on my 95 mercury grand marquis LS. Not a spot for fuse, and changed lcm please help


But there would be a fuse for those lights, somewhere. The park/taillights and the license plate light would for sure be on the same fuse. Not sure about the shift indicator light, that might be on a separate fuse like for dash lights and/or instrument panel lights. But yes, you need to look at all your fuse panel sites again, there might be more than one under the dash, too, maybe behind the glove box or under the dash on the passenger side.

Check to see if your brake lights and rear turn signal lights work. Do they still work right? If they don't work either, there may be a ground problem with the rear lights. If still no help with the lights, one would need a voltmeter and a wiring diagram of the lights to track down the problem. Things like looking for power along the electrical path from the switch to the fuse panel to the lcm to the bulbs. First find the fuse. good luck.

Dash lights dont work on my 97 blazer


All lights, or just your illumination lights? Illumination: bulbs need replacing. All lights; SERIOUS problem. There is a dash panel fuse on car. check that. Has anyone done any work recently under dash( like installing a radio)? May be they accidentally pulled a connector loose behind dash. Need to pull your instrument cluster to check that. Usually two big connectors with lots of wires going to back of instrument cluster. If no power at all with key on: check under hood at power distribution center for a main big fuse out.

The dashboard lights does not come on,need to hit hard on top of dash then only i\the lights comes on and only half of the lights


Sounds like a contact problem or wiring broken problem somewhere behind the instrument panel.
Or, the instrument panel is defective if hitting it seems to affect it.

Car wont start. the cigerette light windows and dash clock dont work. the car turns over good, just dont start.


I would start near the battery and look for a broken wire feeding the fuse block under the hood. Also, look in the fuse block for a main fuse that could be blown. It would be very helpful if you would find a schematic for your car and see where the wires are connected and where they draw their power.

You are getting power to some devices, but not all devices. You will probably find a broken wire or blown fuse somewhere causing the problem.

Instrument Panel Doesn't light Up!


First check your fuses. If the fuses are good you have to check the wiring around and behind the cd player. There will be a loose, broken, or disconnected wire causing the problem. The wire could be a ground or hot wire. To find this if it is not a fuse will be time consuming but that is what has to be done there is no real short cut in this case.
