In this guide, we will provide steps on how to troubleshoot this issue and get your liftgate working again.

Checking the Liftgate

The first step in troubleshooting an issue with the power liftgate is to check the actual hardware of the liftgate itself. Ensure that the liftgate’s hinges are free from any debris or obstructions and that the latch is completely closed. If either of these issues are present, they should be addressed before moving on to further troubleshooting steps.

Inspecting Wiring

After checking the hardware of the liftgate, inspect all of the wiring associated with it. Look for any signs of corrosion or damage to wires and make sure all connections are tight and secure. If there is any visible damage to wires or connectors, they should be replaced before proceeding further.

Testing Motor

If all wiring appears undamaged, then it may be necessary to test the motor that operates the power liftgate. This can be done by using a multimeter to measure voltage at various points in the circuit while operating both manually and with the remote keyless entry system (if equipped). If no voltage is detected at certain points when testing manually but is present when tested with remote keyless entry, then there is likely an issue with the motor itself which will need to replaced or repaired by a professional technician.

Replacing Motor Relay

If all other components appear undamaged and when tested manually no voltage was detected at certain points but was present when tested with remote keyless entry, then it may be necessary to replace the motor relay which controls power supply to lift gate motor. The relay can usually be found near other relays under hood near battery or fuse panel inside cabin depending on model year, so consult your owners manual for exact location information prior to attempting replacement procedure. After replacing relay re-test circuit as described above before proceeding further.

Replacing Control Module

If all other components appear undamaged after testing but still no voltage was detected at certain points when tested manually or with remote keyless entry system then it may be necessary to replace control module which operates entire system including locking/unlocking doors as well as activating/deactivating power liftgate feature from both inside and outside vehicle cabin depending on model year so consult your owners manual for exact location information prior attempting replacement procedure if required . After replacing control module re-test circuit as described above before concluding diagnosis process .
