    Power Trunk Problems in 1997 DeVille

    Hello everyone:

    About a couple weeks ago, the power mechanism on the trunk stopped working. The trunk will not open by the button in the car or the trunk button on the key remote. You can use the key to open it from the outside, but also, the thing that goes up to pull the trunk down when you close the trunk also does not work. I was not around when this happened but my mom said that she had to open the trunk with the key and could not get it to close. Someone who lives nearby where we are had to help get it closed and I don't know how he did it. I'm wondering what could be causing the power motor for the trunk to stop working all of a suddenly. The gas cap door button still works luckily.

    Check your fuses. Always a good place to begin.

    I believe one is under the hood and another in the trunk behind the liner against the rear seat back, but the owners manual will tell you where they are.

    Sounds like you have lost all power to the trunk motor/release mechanism.

    Pull down motor fuse is a 20 amp and is behind the trunk cover in the trunk, drivers side. Not aware of any trunk circuits in the engine bay.

    Re: Power Trunk Problems in 1997 DeVille

    The culprit is probably the switch mounted on the lower side of the latch inside the trunk. These things fail as does the switch on the trunk lid side but this lower one is usually the one to go. It controls "the thing that goes up to pull the trunk down". $20 part and easy to replace. Typically it is only the switch and the motor it controls will not need to be replaced. Hope this solves it for you.

    If I were to go check, what if I can't get the trunk closed again?

    Still haven't fixed the trunk motor. And I'm still wanting to know what I could do to get the trunk to close the thing on the pull down doesn't come up? What do people do? I really need into my trunk.

    Even without it coming up you should still be able to close the trunk. It sounds like it's teh switch but you also need to check for power to see if the fuse is blown.

    if the latch doesn't come up, do I slam the trunk closed then? When you press the trunk release button in the car or on the key fob, it doesn't even open the trunk, but you hear a little noise of some sort back there.

    I would probably never slam the trunk. A person slammed mine once and I almost flipped out at em. You might break something that is not yet broken/not yet your problem when slamming.

    You have to get that latch up to close it manually.
    Try playing with the lever (switch) and it's contacts.
    If worse comes to horrible, you can pull the motor and manually screw out the latch, but the correct length will be trial and error until you get it right.

    Re: Power Trunk Problems in 1997 DeVille

    Funny that this came up. I just replaced the lower assembly. The one with the pull down motor, switch and latch that the motor pulls up and down. There is another switch on the top latch mechanism as well. You can test it by:
    1) Hold the top trunk switch up
    2) Push the bottom switch down
    3) This should pull the latch down
    ***
    4) Release both switches latch should move up.

    The bottom mechanism is quite a cleaver assembly. The latch moves a switch up and down. That switch reverses polarity on the motor to change direction. The other switch on that assembly is pushed by the trunk lid. When down power is put to the motor until the latch pulls the inside switch down. When the trunk is released that switch is opened and power is put to the motor up till the latch moves the other switch in the up position.

    I took the lower assembly completely apart. Watch out for the brushes for the motor you have to move them up (they are spring loaded) to get the rotor back together. I ordered the complete lower assembly because I couldn't find the switch assembly. It cost me $244 from AMAZON.

    On the ones I've done down almost all the way usually works. One problem too is not just that it won't latch if its down too low but that it can be almost impossible to turn the key to open it again.
