Nissan Altima: Altima remote trunk opener problem

    Altima remote trunk opener problem

    Hi all

    My Altima has very recently developed a problem where I cannot open
    the trunk remotely anymore (from the remote or from within the cabin).

    When the trunk is open and I press the trunk open button, the release
    lever does move. When it is closed, nothing happens (I hear a slight
    buzz but trunk remains closed).

    It is opened by means of a assembly that contains a motor and gears.
    Opening this assembly up, everything looks fine. No stripped gears or
    anything. I re-lubed it and put it back together. It still does not
    work.


    It almost seems like the pulse that normally drives this is too short
    (is it perhaps driven by a capacitor that's leaking or something?).
    Looking at this signal on a scope it is not a nice square signal - it
    goes to 12V but very quickly droops to 0 volt.

    When I momentarily apply 12 V to the motor from a external source, the
    trunk opens fine.

    Has anyone out there seen this before? Where is the drive unit located
    for this motor?

    Thanks!

    My first thought is that when its closed, there is a bind or
    misalignment that is more than the solonoid can overcome.

    What year is the Altima, do you have a FSM for it?

    Put downward pressure on trunk lid and have someone operate cabin
    release, remove pressure when you feel it activate. Alternatly put
    upward pressure on it and try the same thing. Lubricate all pivot
    points on hinges and torsion bar.

    The circuit might have too much resistance, if you can trace the
    circuit with the help of a circuit diagram you can disconnect each
    connection and clean and apply dialectic grease and replug.

    read the owners manual, it will tell you how to enable/disable the remote
    trunk release feature

    It is a 2000 -- I don't have the service manual. Just a third party
    manual, which really doesn't show ver much in the way of schematics --
    certainly not the trunk solenoid detail.

    Thanks for the suggestion -- I've tried fiddling with the trunk but to
    no avail. I also libricated all moving parts also.

    When I put my finger on the actuator coming from the solenoid
    (actually a motor with gears inside, btw), I feel a decent amount of
    pressure only when it first actuates. If I actuate twice (one after
    the other) the solenoid hardly moves.

    I'll try to trace the wire back where it came from. Hard to do,
    because it immediately goes behind a panel.

    Thanks again.

    Thanks but the solenoid (motor, whatever it is) is moving when I try
    to open the trunk so it is enabled.

    the solenoid is live all the time, you need to make sure the valet lever is
    in the correct position on the trunk latch

    Appreciate the suggestion.

    I think the valet lever is in the correct position because, when I
    hook independent wires to the solenoid and make them go to a
    motorcycle battery, the trunk opens fine (of couse I just momentarily
    pulse the unit - don't want to burn it out).

    So the basic mechanism works - it just seems like whatever is driving
    this solenoid lacks the capacity to move it properly.
