    the relays are part of the passenger fus box The fuse panel is located under the right-hand side of the instrument panel. Remove the panel cover to access the fuses.

If the lift gate doesn't open it may not be the solenoid. Check to see if someone dropped a coin in the front cig lighter outlet in the console. If so, remove coin, relace fuse in fuse box, and liftgate should work fine. They are on the same electrical circuit. This has happened to me twice.

2009 hhr hatch wouldn't lock so I removed #11 fuse and I found info on it in thr forum. But without the #11 fuse it won't unlock at all. Battery is good. Has anyone had the same issue?


Rear Liftgate Release
The liftgate can be released by operating the liftgate release switch. The gear selector may be in any position, but the doors must be unlocked and the vehicle must be stationary for the liftgate to release.
Pressing the liftgate release switch closes a contact providing a ground for the liftgate release switch signal circuit. The body control module (BCM) will detect the voltage drop and command a ground to be supplied to the liftgate release relay control circuit thus energizing the L/GATE RELSE relay which provides voltage to the liftgate latch. When the doors are locked, the BCM will disable the liftgate release system by ignoring the liftgate release switch input command and not providing a ground for the L/GATE RELSE relay.

Fuse # 10 - 20 amp supply's B+ voltage to the L/GATE RELSE relay located in the under hood fuse/relay box.
The BCM controls this relay from input from lift gate release switch.

Fuse #11 is 11

I have a 2005 GMC Yukon that the rear hatch does not lock. Wouldn't be a problem but no manual key hole to lock it. Must be some kind of lock sensor. Is on the driver door panel or by the hatch?


The rear hatch locking is computer contolled .
The BCM also runs diagnostics on the liftgate lock relay control circuit and will set DTC B3825 as current and also send a Class 2 message to the DIC. The DIC will display REPLACE LIFTGATE FUSE to inform the driver that a fault has been detected in the liftgate lock circuit and that the liftgate is not locked. Faults that will set the DTC and cause the DIC to display the message could be any of the following:
• An open ECC fuse
• An open or short to ground in the liftgate lock relay battery positive voltage circuit
• A faulty liftgate lock relay
• An open or short to ground in the liftgate lock relay control circuit
• A short to ground in the liftgate lock actuator lock control circuit
• A faulty BCM

The liftgate lock relay supply and coil sides receive a constant voltage through the battery voltage supply circuit and the ECC fuse. The normally closed contact is connected to ground and the control side is connected to the body control module (BCM). A lock function will occur when a door lock switch activation, keyless entry lock transmission, auto door lock function or a liftgate lock function has been received by the BCM. The BCM will then ground the control side of the liftgate lock relay. This energizes the relay and allows voltage to be applied to the liftgate lock actuator lock control circuit. Since the other side of the liftgate lock actuator is connected to the normally closed contacts of the door unlock relay to ground, the liftgate will lock. When an unlock function occurs the BCM will ground the control side of the unlock relay and the rear doors and liftgate will unlock.
The power door lock system consists of the following components:
• The driver door module (DDM)
• The passenger door module (PDM)
• The body control module (BCM)
• The driver information center (DIC)
• The rear door lock switch
• The door lock relay
• The door unlock relay
• The liftgate lock relay--utility vehicles with liftgate only
• The reversible door lock actuators in each of the doors and liftgate
• LOCKS 20A fuse (rear lock/unlock relay supply voltage)
• ECC 10A fuse (liftgate lock relay supply voltage)

If i were to guess i would say you mite need a new lock actuator , but i don't guess . You could take the hatch inside panel off an check for B+ voltage for the lock actuation as someone pushes the switch . Or have it checked for codes .

Need to replace the liftgate switch, where can I get instructions to do that?


How do you know it need's a switch ?
Rear Hatch/Gate Description and Operation
The lift gate can be opened by operating the switch on the instrument panel. Battery voltage is supplied to the lift gate actuator through the body control module (BCM). The BCM will pulse the lift gate actuator when a release input is received through the key fob, or the instrument panel switch. Did you test voltages ? Check for BCM DTC'S - diagnostic trouble codes ?
Circuit/System Description
The lift gate switch is an input to the body control module (BCM). The BCM supplies battery voltage to the signal circuit and when the lift gate switch is activated the signal circuit voltage goes low. The BCM controls the lift gate release actuator assembly through the LIFTGATE relay. When the lift gate switch signal is activated, the BCM enables the LIFTGATE relay by applying battery voltage to the lift gate relay circuit and the relay is energized when the BCM grounds the LIFTGATE relay control circuit. When the relay is energized battery voltage is supplied to the lift gate release actuator assembly through the lift gate release actuator control circuit.

Power lift gate will not operate


You have to pull the inside door panel off an check it out , only way !
  • The lift gate latch release is inoperative/does not operate correctly
  • Circuitry
  • Liftgate release switch (integral to the liftgate release handle)
  • Liftgate release motor (integral to the liftgate latch)
  • Power liftgate module
  • SJB
  • Go To Pinpoint Test F .
Normal Operation The smart junction box (SJB) does not release the liftgate unless the doors have been unlocked electronically or the request is initiated from a remote keyless entry (RKE) transmitter.
The SJB sends a voltage signal to the liftgate release switch (part of the liftgate release handle) through circuit CPL45 (BN). When the switch is activated (the handle is pulled), the signal is routed to ground through circuit GD150 (BK/WH). When the SJB detects a request from the liftgate release switch, the SJB provides voltage through circuit CPL10 (BN/BU) to the liftgate latch release motor (integral to the liftgate latch) (vehicles with a manual liftgate) or the power liftgate module (vehicles equipped with a power liftgate). For vehicles with a manual liftgate, ground for the liftgate latch is provided through circuit GD150 (BK/WH).
DTC B2666 - is an on-demand DTC that sets when the SJB detects a short to ground from the liftgate release switch input circuit.
DTC B273A - is an on-demand DTC that sets when the SJB detects a short to ground from the liftgate latch release output circuit.
DTC B273B - is an on-demand DTC that sets when the SJB detects an open or short to voltage from the liftgate latch release output circuit.
    Possible Causes
  • Circuit CPL45 (BN) open or short to ground
  • Circuit CPL10 (GN/WH) open, short to ground or voltage
  • Circuit GD150 (BK/WH) open
  • Liftgate release switch (integral to the liftgate release handle)
  • Liftgate release motor (integral to the liftgate latch)
  • Power liftgate module
  • SJB
Your best bet is to take it to the dealer !

Where is the manual liftgate sensor located 2009 Equinox


The liftgate can be opened by operating the switch on the instrument panel. Battery voltage is supplied to the liftgate actuator through the body control module (BCM). The BCM will pulse the liftgate actuator when a release input is received through the key fob, or the instrument panel switch.
Not sure what your talking about . There is no sensor. there is a relay in the I/P fuse box LIFTGATE PCB relay . an a lift gate actuator motor inside the door . An there is a door ajar switch ,which is part of the latch mechanism. Do you have light lit on the instrument cluster - a picture of a little car with a door open , an maybe a chime sounding ?

2000 explorer rear wiper inop.


Make a preliminary evaluation by checking 7.5A FUSE 12 in the central junction box and 15A FUSE 5 in the battery junction box. If the fuses are OK, the problem may be with the up/down relays, the liftgate wiper motor circuit, the liftgate wiper disable switch, or even the general electronic module (GEM).
