Does it have a power lift gate ? Do you know anything about automotive electrical systems ? How to use a wiring diagram along with a digital volt ohmmeter to test electrical circuits . ?
Power Liftgate
The power liftgate feature will allow the customer to automatically open or close the liftgate by activating the interior open/close switch, the remote keyless entry transmitter, or by manually initiating liftgate movement. The power liftgate uses a power cinch system to latch the liftgate.
The power liftgate system consists of:
- Power liftgate control switch (located in the overhead console)
- Power liftgate motors (located in the rear headliner area)
- Optical sensor and power liftgate encoder wheel (located in the left power liftgate motor assembly)
- Pinch strip switches (located on the body by the liftgate)
- Home position switch (located on the cinch actuator)
- Forkbolt switch (located on the cinching latch assembly)
- Detent switch (located on the cinching latch assembly)
- Liftgate close chime module (located in a unit external from the power liftgate module)
The forkbolt and detent switch are located on the cinch latch assembly and the home position switch is located on the cinch actuator assembly. For information on removal of the latch or cinch actuator assembly, refer to Section 501-14 .
The power liftgate may not operate under the following conditions:
- a low voltage or dead battery.
- a disconnected battery.
- a power liftgate that has been left open for more than six hours.
- a power liftgate that has been manually closed and left ajar.
If any of these conditions has occurred, the power liftgate must be reset before performing any pinpoint tests. For additional information, refer to Power Liftgate Initialization .
Power Liftgate Initialization
NOTE: If the power liftgate system is turned OFF in the message center, the system cannot be activated with any switches or with the liftgate handle. The system will need to be turned ON for any power operation to occur.
NOTE: The power liftgate may not operate under the following conditions:
- a low voltage or dead battery.
- a disconnected battery
- a power liftgate that has been left open for more than six hours.
- a power liftgate that has been manually closed and left ajar.
If any of these conditions has occurred, the power liftgate must be reset.
- Manually close and fully latch the power liftgate.
- NOTE: If the power liftgate does not open during this step, refer to the symptom chart to diagnose the power liftgate for no operation. Power open the power liftgate by using the keyfob or overhead console switch.
- Once the power liftgate is fully open, close the power liftgate by using the keyfob or overhead console switch.
- your best bet mite be to have a qualified repair shop check it out .
