    Air conditioner problem:
    AC fan does not work. Max/AC does not cool. Norm/AC cools only when vehicle is moving. No air movement when vehicle is stationary. This has happened two times before, but started operating normal again within a few minutes.

      Could be electrical problem. The wirings are frayed or loose and there's a high resistance in the circuit, this should be inspected, refer to certified electrician.

    Airbag light stays on. What are some causes?
    132k miles
    • Nissan Technical Advisor
      The airbag light or SRS - supplemental restraint system appears when the ECM has lost connection with the crash sensor or there's an electrical fault happened after a service in the vehicle interior. By removing the battery negative cable for few minutes the SRS light may disappear but will not resolve the problem and the airbag might not deploy during collision. Bring it to the dealer to have it scanned and fixed and read the TSB and Recall bulletin for your car.

      Are you asking about how to change the transmission fluid? Because you do not remove the pan for the engine oil.

      You mean why is'nt battery charging by the alternator. When engine on and alternator connected voltage across battery terminal post should read 13.5-14.5 volts. If is could be a bad battery.
      2/28/2011 peanut
      no it aint a bad battery .one of my wires that go to the alternator should make the alternator charge and it aint got no juice to it . i need to no why it aint got no juice and how many volts should it have to make it hold a charge.i can hook it it up direct and it well charge but i think 12 volts is to many.and i got another question none of my guages on the dash well work at all like my speed o/gas g.rpm g.and heat g.

      What was your reason for replacing the alternator, to correct this squealing? Is this a kind of squealing noise like a belt makes on some cars, you know what I mean. get me up to speed how this problem came to be please and that helps alot.
      2/25/2011 Bill
      It is described like a capacitor reaching max capacity letting of pressure
      2/25/2011 dorinda
      yes, we were replacing alternator to correct the sqealing, and yes it makes the sound of the belts
      2/25/2011 dorinda
      bill thats what its doing as soon as we hook hot wire it like loses pressure

      The alternator generates direct current for recharging the battery
      and for powering vehicle electrical loads.
      A 12 volts devices such as a starter solenoid or a starter relay may shorted and are the common cause to make the alternator failed to operate. The squealing noise is from the diode rectifiers in the alternator.

      ok so what should i do
      2/25/2011 dorinda

      Is the alternator belt new and is it being held tight at all times by the auto-tensioner. VERIFY that you do not simply have a belt with a very glazed surface caused by slipping or excessive wear. remember, an alternator when it engages places a very heavy load on a drive belt that turns it. Do not assume that the cause MUST be in the alternator circuit.
      2/27/2011 Bill
      I'm not sure everyones on the same page.Dorinda, unhook negative battery terminal clamp and srt aside. Hook up the best you know how the alternator wiring, should be a harness plastic multi-wire connector, a black ground wire ussually near bottom of alternator and a red wire positive connector near top side of alternator. The red,positive one must have an insulating rubber or black plastic piece aficst to stud of alternator that cannot be shorted to ground. Then hook up battery clamp. If you h

      have a voltmeter/ohmmeter, with before connecting battery back up check to see if you have continuity between the positve alternator stud threaded post and the metal case of the alternator, There shouldn't be any, Meter should read high as in infiate resistance, if not you have a ground short in this circuit. Some meters beep in Ohms mode, there should not be a beep.
      2/28/2011 dorinda
      ok Bill, I will try what you said and see if that works. I've got to work the next few days but as soon as i get a free day I will try what you said and let you know how that went.I really do want to thank you for your advise
