Nissan Altima Electrical Issues



  • My best guess is that doing an internet search will show you the location. I also think that you can access the fuses under the dash, near the hood release. (Left side) The lid to the box will normally tell you the location and function of each fuse. I trust you may have the tool to remove. (No big deal, fingers work.)

    Do you have your manual? It should show you which one is for the heater, but if you don't have one, a Google search may very well help as skinsfan3 suggests, or someone here may be able to help. It would probably help to know what year and model your Altima is.
  • yes i do have standard and it is a 2002 altima 2.5 S. please help it is really cold and i have a 2 yr old son i have to take to daycare in the morning

    If anyone knows the answer, I'm sure they'll chime in. Whether you'll hear from someone before you have to leave in the morning just depends on who happens to stop by here. I'd try the google search that was recommended while you are waiting.

    Good luck.
  • I have a 2003 and don't know where the fuses are. I did have an 86mr2 and the fuses were located under the hood. I wonder if your problem is really the fuse? I know that sometimes replacing water in a radiator might result in a pressure problem, causing the heating sytem no become inoperable. I hope it is only a fuse, which should run you about 2 bucks. ;)
  • i did have to change my o2 sensor and i disconnected and drained the radior could that be the problem if so how can i fix that
  • I think that should be addressed in your owners manual, or a shop manual if you have one. Don't forget about an internet search. By the way, I would not fiddle around with a change in the thermostat. In the old days, we used to take them out, but that is a crappy way to solve what should be an easy problem. If you are a do-it-yourselfer, watch out since the thermostats used to be housed in a casting and tightening up would crack them. I wonder what they do these days?
  • I have a 2000 Altima GLE. I was glad to read about your experience because my car is doing the same thing except so far the engine has not stalled, however, if I am on the highway, the cruise control goes right out and the car quickly slows and continues to slow until I accelerate. The car continues to run, but the speedometer, the odometer, etc. is completely blank. After the car is off for a long time, when I restart it, the speedometer, odometer, etc. are working, but if I am on the highway again, or if I use the cruise control, it happens all over again. It sometimes happens when I drive in the city, but not as often. If I can't find the solution, I am afraid the problem may become progressively worse with the car stalling in traffic and other electrical problems. Urgent, Please let me know if the new instrument gauges you had installed has solved this problem!! Thank you so much!!
  • The Nissan dealer where I bought the car replaced the instrument cluster under the extended warranty. (I only had to pay $50 deductible). The cluster consists of different gauges: odometer, temperature, fuel, tachometer. So far I have driven the car over 2050 miles and the problem has not recurred. The displays have not gone out and I have not experienced any slowing down or stalling.
  • the other day i was parked on an incline and my car would not start so i had it towed and they found out after bout 4 hours my spark plugs were i am in the same place 2 weeks later i took them out today after work and only 2 were wet and 1 was burned so i dried them off and installed them and still no start it sounds like it is trying to start but just wont somebody please help me!!!!!!!!
  • I have a 2000 Altima GXE and I have been having problems lately with my lights on my radio fading in and out on occasion.  I also have a problem starting my car sometimes, it is fine when I first start it up in the morning but after that first start it will sputter out if I do not immediately press on the gas.  When I am at a light the RPM's go below 1000 and it feels like it is going to conk out on me.  Now I have noticed that the brake light is on the dash but my emergency brake is not up.  I thought it might be because it was cold and maybe it is just stuck enough to flash the light.  Any help on these problems would be great, I am supposed to go to the shop next thurs. and I want to have an idea of what to expect plus I don't wanna get ripped off. Thanks,Jayson
  • This has happened to me - twice. It is in the shop now - the service manager says it a mystery. I was wanting to know what you found out about your car.
  • Mine (2003) altima would nor start after it stayed overnight for a couple of days. I need a new alternator. No poblem since.

    I have a 2001 Altima. The horn does not work. I changed the horn relay under the hood and it still does not work. I need know if there is a fuse for the horn in the fuse box under the dash board. I don't have the cover for the fuse box where it should be labelled. The owner's manual does not have the fuse diagram in it. If you have the diagram I would love to have it. Also could you suggest trouble shooting steps. Thnx

    I believe you will find what you need via a nt search. That is a good place to look for he factory manual. It is not impossible that the problem may be related to how the wheel cover sits on the wheel. That is just a guess on my part.
  • I have a 2000 Nissan Xterra and my horn does not work either. My fuse for the horn is under the hood near where I found the horn relay. My horn fuse was good so my next step is to replace the horn relay. I checked with an electrical mechanic today and he is my next stop if the horn relay does not fix my problem, but I am assuming I have an electrical problem because my cigarette lighter where I plug in my cell phone charger is no longer working either.
  • My front passenger side window will not go up and I noticed that the dorr locks do not work either. This all happened at 37000 miles 1 thousand after the warranty. Has anyone experienced this problem and if this is a fuse issue how do I find it. The Altima is a 2007 4 cyl
  • Consider yourself luck. My 2003 altimora started locking doors on its own early on. Which means that I have to be careful and remember to take my keys with me. I noticed this happens when I open the rear doof on the driver side, although it now doesd it on its' own.
  • My 2003 Altima has been giving me problems with the main door switch (drivers door). The swith quit operating some windows and I had it repaced for over $170. It worked great (except for rear door behind the driver) for two days and now is having problems again. It is not working the window or the doors locks properly. Any clues as to what may be going on??
  • Welcome to the club. I have a 2003 and the door behind the driver's seat has always managed to lock al the doors, after it has been open for a few minutes. Now It seems that if I close my doors, all of the locks shut. So I have to use caution and make sure I take the keys with me. My latest problem is that the roof light doesn't. whenever I open the driver's side rear door. The other door works. I am abut to try to fix the light problem, but I have no idea as to what is wrong with the electrical and doors. I figure there must be a solenoid somewhere that has gone bad. It may very well be that this is a defect in all 2003 models. I love the car and it has been relatively trouble free over these years
