Why doesn't pull down switch grab the trunk lid?

You can fold either side of the rear seatback down for more cargo space.
To lower the rear seatback, follow these steps:

Open the trunk and pull one or both of the small handles located in the center of the trunk.
Once the handle is pulled, the seatback can be pushed open through the trunk, or pulled open from the inside of the vehicle.

Sorry ,but you need the trunk open ! What's wrong with your's ? loose your key . trunk release inside the vehicle doesn't work .

Your best bet , have a qualified repair shop check it out . May have DTC'S diagnostic trouble codes stored .
DTC B3267: Trunk Release Output Circuit Low
DTC B3268: Trunk Release Output Circuit High

The rear compartment release circuit consists of the following:
• The intergrated body control module (IBCM) fuse
• The rear compartment lid release relay
• The rear compartment lid lock release actuator
• The rear compartment lid release switch
• The cargo lamp/trunk ajar switch
The rear compartment release circuit operates as follows. Battery positive voltage is applied at all times to the rear compartment lid release relay. The rear compartment lid release relay is energized by either depressing the rear compartment lid release switch, or when the IBCM receives a rear compartment release signal from a key fob. The IBCM then provides a path to ground on the rear compartment lid release relay control circuit, energizing the rear compartment lid release relay. When the rear compartment lid release relay is energized, battery positive voltage is supplied to the rear compartment lid lock release actuator causing the actuator to energize releasing the rear compartment lid. The rear compartment may be released with the dash mounted rear compartment release switch. The ignition must be in the OFF or ACCESSORY positions for the rear compartment to be released with a keyless entry transmitter fob (RFA). The rear compartment may also be released by an OnStar commanded using RFA functionality.

Do you know anything about automotive electronic's ? The trunk release is controlled by electronic control modules . Having the vehicle check for DTC'S - diagnostic trouble code's should be the first step in the diagnostic procedure . Then reading how it work's !

Rear Compartment Lid Release System Components
• Body control module (BCM)
• Remote control door lock receiver
• Interior rear compartment lid release switch
• Exterior rear compartment lid release switch
• Rear compartment lid release actuator
• Trunk release relay

Rear Compartment Lid Release Operation
The interior rear compartment lid release switch receives a signal from the driver door switch assembly (DDSA). When the interior rear compartment lid release switch is activated, the signal circuit is pulled to ground. The DDSA interprets this and sends a GMLAN serial data message to the body control module (BCM) requesting the rear compartment lid be released. The BCM responds by applying battery voltage to the trunk release relay control circuit which energizes the TRUNK RELES relay. The trunk release relay is supplied with battery voltage at all times. With the relay coil energized, the relay switch contacts close allowing battery voltage to flow to the rear compartment lid release actuator causing the rear compartment lid to release. The rear compartment lid release actuator is permanently grounded at G402.

The trunk release relay is located in the rear fuse box located under the back seat.

The rear compartment lid release system consists of the following components:
• Body control module (BCM)
• Folding top cover actuator
• GMLAN serial data link
• Keyless entry transmitter
• Rear compartment lid ajar switch
• Rear compartment lid release actuator
• Rear compartment lid release switch
• Remote control door lock receiver (RCDLR)
• Trunk fuses
• Trunk release relay

Rear Compartment Lid Release System Operation
The rear compartment lid can be released by operating the rear compartment lid release switch or pressing the rear compartment lid release button on the keyless entry transmitter. When the rear compartment lid release switch is operated, the rear compartment lid release switch signal circuit to the body control module (BCM) is switched to ground. The BCM receives the rear compartment lid release switch input and applies ground to the trunk release relay control circuit. This energizes the trunk release relay coil, closing the switch side contacts, allowing battery voltage to be applied to the rear compartment lid release actuator and folding top cover actuator, releasing the buttresses and opening the rear compartment lid. Ground for the rear compartment lid release switch is provided at G300. The rear compartment lid ajar switch, rear compartment lid release actuator, and folding top cover actuator are provided ground at G301. The rear compartment lid will not release until the vehicle speed is zero and in park.

Do you know what DTC'S - diagnostic trouble codes are ?
DTC B3265 01 : Trunk Relay Output Short to Battery
DTC B3265 06 : Trunk Relay Output Short to Ground or Open

Do you know what a relay is an how it works ? TRUNK release relay located in the underhood fuse / relay box.
VEHICLE RELAYS Operation Diagnosis

Hi Jeff,
I was going to say, check fuse/ jump the load side of relay Good post.

If the rear seat has a pass-thru or can fold down, there should be a manual trunk lid release inside the trunk near the lock. Just grab the handle and pull.

There is a valet switch in he center console and make sure it is switched on so it will open. Does it open from trunk switch on the trunk or from the manual key cylindr in the trunk deck lid? If it does not work from the manual key release on the deck lid then the lock in the trunk is faulty and will need to be drilled and removed unless your a lucky one and have the ski boot opening in the center of backseat fold down arm rest ? If there is a opening then use a hanger and grab the emergency release handle at the right rear of the trunk deck lid underneath, it is glow in the dark colored.

If it works intermittently, you probably have a damaged wire -- my guess would be where the wiring harness goes to the trunk lid. The constant motion of use can damage the wires internally. They still look ok on the outside usually, you'll have to check them electrically (with a meter or test light) The other possibility is damage to the harness that goes to the latch from something moving in the trunk and hitting it. Good luck.

Did you get the trunk open? having the same problem wirth my '05 Spectra and it apparently is not covered under the warranty.

Replace thr pulldown switch .

you should replace the trunk pull down mechanisim
