Trunk release clicks, but won't release

Do you have keyless entry ?
The remote keyless entry system performs the following functions:
• Locking the vehicle doors
• Unlocking the vehicle doors
• Opening the rear compartment lid

Rear Compartment Lid Release Circuit Description
The BCM receives a signal via Class II from the PCM indicating the position of the transaxle range switch. When you press the release button on the RKE transmitter, a signal is sent from the remote control door lock receiver through circuit 377 to the BCM. Then, the BCM sends a ground signal through circuit 253 to the rear compartment lid release relay. The relay receives power from the DOOR LOCKS fuse. When the relay receives the ground from the BCM, the relay's internal switch closes sending B+ (via circuit 56) to the rear compartment lid lock release actuator. A ground is always supplied to the actuator through circuit 350. When B+ is received at the actuator through circuit 56, the rear compartment lid releases.

You could jumper pins at the rear compartment lid release relay , this would open it .

Behind the IP compartment, attached to the underside of the cross-car beam . Need to pull glove box out .

Have you got the valet switch turned on?

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.

Hi Annette, Im AL the owner of Big As Auto Repair.

Annette, if you are already able to get inside the trunk, remove the lever that goes to the lock actuator because the actuator may be locked up. Then see if it will open. NOTE: If the lock solenoid is mounted to the latch this will not work. If that doesn't help, then see if you can remove the bolts that hold the latch to the trunk and open the trunk that way so you can see better what the problem could be. Keep me posted at my auto-repair-website here: http://www.bigasautorepair.com/

something push on trunk release switch in glove compartment when you open the glove box it release the switch

Button inside glove box (on left side) disables trunk opening...just push it again and trunk can be opened...worked for my 2007 Avalon. I must have bunped it by accident to disable the trunk and didn't realize the button existed. T

Check it again, maybe you did not reassembled it right.

check to make sure the trunk release on switch in the glove compartment isn't turned off. It's located in the upper left in the glove compartment

My avalon 2002 trunk was not opening. The problem was a little switch in the glove compartment was depressed I puched the switch back in and wala everything was just fine again. A lil black switch in the glove compartment. wish u the best.

We finally flipped the glove compartment trunk switch (found on the left side inside the glove compartment) to 'on' then the trunk switch by the driver seat worked. We could not tell the trunk switch in the glove compartment was an on/off switch, we just kept searching and finding,
