Sometimes the tailgate does not unlock.

It sounds like there may be an issue with the tailgate on your 2014 Equinox. Here are a few things you can try to troubleshoot the problem:

1. Check the tailgate latch: Make sure the latch on the tailgate is not damaged or stuck. You can try lubricating the latch with a penetrating oil to see if that helps.
2. Check the tailgate hinges: If the tailgate is not opening smoothly, the hinges may be damaged or worn. You can try lubricating the hinges to see if that helps.
3. Check the tailgate motor: If the tailgate is not opening or closing properly when you use the switch in the car, the motor that operates the tailgate may be damaged or not functioning correctly. You can try testing the motor to see if it is working properly.
4. Check the wiring: If the tailgate is not opening or closing properly, there may be an issue with the wiring that connects the tailgate to the car's electrical system. You can check the wiring for any damaged or loose connections.

If none of these steps help to fix the issue with your tailgate, it's possible that there is a more serious problem with the tailgate itself. In this case, it's best to consult a mechanic or the manufacturer for further assistance.

i have the ford galaxy a 99 diesel ,my problem was the wires in the rubber boot from body to tailgate ,, ,Just to make sure it doesnt lock itself up i fitted a pull wire from the lock to left side that i pull out with a length of wire , then pull the wire .. Most of the locking is controlled by the drivers side lock as is common with a lot of modern cars so you may need to replace this lock ,, its a sealed unit iam afraid so just replace it .like a lot of the electronics i am well known for by passing them like the immobilisor on the fuel pump ,that is all removed and wire straight to the shut off valve ,, Think its the door lock on your car is the problem BUT i could be wrong

Sonds like the lift motor has stopped working.

Check the wiring harness from the tailgate to the body. It may be loose or damaged.

Try to reset the tailgate by removing the no.7 (7.5 amp) fuse in the underdash fuse box. Open and close the tailgate manually, reinstall the fuse, and try the open tailgate button. If that doesn't work you would have take it to the dealer, where they can check for DTC's (diagnostic trouble codes). Honda Al
