Sounds like the button (switch) has failed, not the solenoid or the actual latch that opens/pops when you hit your remote, remote is just controlling/activating latch by another means. (remote is a different switch controlling the circuit) you may want to look in owners manual and make sure that there isn't a fuse between switch and solenoid that has went bad. the remote may be activating the solenoid on other side of circuit (downstream of fuse)

Can not open trunk on a pontiac soltice. No clicking sound from remote or switch in glove box fuses are ok


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.

My remote is bad and the button on the door of my 2008 saturn aura xr will not open the trunk


How about a key ?

Luggage Compartment Description and Operation (Sedan)
Rear Compartment Lid Release
The rear compartment lid can be released in one of three ways:
• Inserting the key into the key lock cylinder, if equipped
• Operating the rear compartment lid release switch
• Using the keyless entry fob
To operate rear compartment lid with the rear compartment lid release switch or with the rear compartment release button on the key fob, the gear selector may be in any position, but vehicle speed must equal 0 for the rear compartment lid to release.
When the rear compartment lid release switch is pushed, the rear compartment lid release signal circuit to the body control module (BCM) is grounded. BCM then grounds the coil side of the trunk release relay through the trunk release relay control circuit. With this voltage is applied to the rear compartment lid release actuator, opening the rear compartment.

do you know how to do electrical testing ?

Circuit/System Verification
Ignition ON, observe the scan tool Trunk Release Switch parameter while pressing and releasing the rear compartment lid release switch. The parameter should change between Active and Inactive.
? If the parameter does not change, refer to Trunk Release Switch Malfunction.
Command the trunk release with a scan tool, the rear compartment lid latch should release the trunk lid.
? If the rear compartment lid latch does not release, refer to Rear Compartment Lid Latch Malfunction

You may want to take it to a repair shop .

2003 Cadillac deville trunk randomly opens on its own when sitting and not running occasionally what could be the cause.


Do you know anything about automotive electrical testing ? how to read a wiring diagram ? How to use a DVOM - digital volt ohm meter ? You can find a free wiring diagram here http://www.bbbind.com/free_tsb.html

The trunk release is controlled by an electronic control moduel .
Trunk Release Relay
Output Controls
The rear integration module grounds the trunk relay when commanded ON. The rear compartment should release.

This vehicle has a very complex body control system of three different computers

The body control system consists of the following 3 modules:
• The Dash Integration Module (DIM)
• The Instrument Panel Module (IPM)
• The Rear Integration Module (RIM)
Each of the 3 body control modules integrate a number of functional systems under the control of a single module. Each module is connected to the Class 2 serial data circuit, many of the control functions are implemented by Class 2 messages.

. Rear Integration Module (RIM)
The various RIM inputs and outputs are described in the corresponding functional areas as indicated on the RIM electrical schematics.
The RIM functions include the following:
• Automatic level control
• CIGAR relay control
• Class 2 communication requiring RIM interaction
• Content theft deterrent
• Fuel door control
• Fuel level sensor input
• Heated seat control
• HVAC blower control
• LK/CYL relay control
• Park brake relay control
• Rear defog relay control
• Rear park assist chime control
• Retained accessory power (RAP) relay control
• Reverse relay control
• Transmission shift inhibit
• Trunk release relay control
• Various controls for the interior lamps


Luggage Compartment Description and Operation (General)
Rear Compartment Lid (trunk) release actuation is controlled by the following components.
• Rear Compartment Lid Release Relay
• Instrument Panel Module (IPM)
• Rear Integration Module (RIM)
• Valet Switch
• Rear Compartment Lid Release Switch
• Rear Compartment Lid Release Actuator
Battery voltage for the coil side of the trunk release relay is supplied through the Valet switch (with the valet switch in the OFF position) by the ALDL fuse located in the Underhood Fuse (Bussed) Block. Battery voltage for the switch side of the trunk release relay is supplied by the Body fuse located in the Rear Fuse (Bussed) Block. When the rear compartment lid release switch is momentarily pressed, it provides a ground circuit for the trunk release signal of the Instrument Panel Module (IPM). When the IPM senses that the switch has been activated, it sends a Serial Data Class 2 message to the Rear Integration Module (RIM). The RIM then provides a path to ground on the F/TNK DR REL relay control circuit. The trunk release relay is then energized, and battery voltage is applied through the switch side contacts of the trunk release relay to the rear compartment lid release actuator. The actuator is connected to ground through a ground splice pack located at the left rear corner of the rear compartment, near the left tail lamp connector.

Trunk locks not opening


This is very complex if your not familiar with how Class 2 serial data communications work . When you press that trunk lid release button it sends a low voltage signal to the BCM - body control module. Here is how the factory service info. says how it works .
When the vehicle is in park and the trunk release switch is pressed it grounds the rear compartment lid release switch input in the Body Control Module (BCM). The BCM then sends a Class 2 message to the Remote Function Actuator (RFA). The RFA supplies an internal ground for the coil side of the rear compartment lid release relay activating the relay. The rear compartment lid release actuator receives battery voltage through the 15 A trunk release fuse when the relay closes. Ground is supplied by G400.
Your best bet is to take your vehicle to a dealer or some other qualified repair shop that has a factory scan tool or a professional grade type .
You could check the TRK/REL relay in the rear fuse/ relay box .Because you can't test the class 2 data to the rear integrated module. Fuse Block Rear

My fuel cover does not lock with central locking


According to WIS, the remote boot release is directly connected to the PSE via CAN
The pneumatic system equipment makes vacuum or pressure available for the following systems:Central locking (CL), (pressure, vacuum)Remote trunk release (RTR), (pressure)- actuation via remote trunk release switch or via radio
AD80.20-P-2002-02B Remote trunk release, general notes on Models 202.01/02/12/12 as of 1.6.97,diagnosis, advanced information, RTR 208, 210 as of 1.3.97, 210.081Actuation of PSE control module:The remote trunk release switch (N72s15) is connected to the PSE control module (combined) (A37) via CAN data buses. The remote trunk release radio signal from the key is conveyed to the overhead control panel control module (N70) via theantenna. This transmits the signal to the electronic ignition switch control module (N73) via CAN data buses. If a valid signal is recognized there the PSE control module (combined) (A37) is actuated via CAN data buses. The remote trunk release IR signal from the key is conveyed to the respective door control module (N69/1, N69/2) via the IR receivers (A26/1, A26/2). This transmits the signal to the electronic ignition switch control module (N73) via CAN data buses. If a valid signal is recognized there the PSE control module (combined) (A37) is actuated via CAN data buses.
If the trunk lid is unlocked the LED in the remote trunk releaseswitch (N72s15) is actuated by the PSE control module (combined)(A37) via CAN data buses.
Special features on model 208.4 (Cabriolet)The trunk lid cannot be released remotely with the transmitter key.The rollover bar (RB)/soft top operation control module (N52)signals via the CAN interior data bus whether the soft top is lockedor unlocked or the power soft top switch (S84) is operated. As long as the CAN message reads:"Power soft top switch (S84) operated" or"soft top unlocked"the trunk lid cannot be released remotely.
