Rear hatch will not unlock so it can be opened.. Both remote & interior switches lock and unlock all doors but not the rear hatch at this time. looked for fueses but did not find any spacific to the rear hatch. How do I get it open.

Rear hatch is locked or unlocked with a key. (if equipped) • To open the rear hatch, insert the key into the lock, turn it to the unlock position and pull up the rear hatch by pressing the handle (DOOR). You can also lock/unlock the latch (but not release it) with the central door lock system. • If unlocked, the rear hatch can be opened by pressing the handle (DOOR) and pulling the hatch up. • To close the rear hatch, lower and push down the rear hatch firmly. Make sure that the rear hatch is securely latched.

sounds like something may be shorted in your rear hatch switch and when you pushed the button to open it you may have blown a fuse. I would check your fuse and make sure they are all still good. I would also try to look inside the rear hatch and check the wires and see if there is something wrong with one of them.

If there is no exterior handle to open the hatch you are in a pickle. The rear hatch interior moulding assembly will have to be removed from inside the vehicle to access the lock assembly. This may crack/damage the moulding assembly as it is not designed to be removed this way. Once removed the door can usually be opened manually and then diagnosed for the problem. It may be a defective lock solenoid or latch assembly. I would have a pro look at it as they know how to disassemble these things with minamal to no damage.

the switch is bad on the rear hatch cylinder

Thanks.

sound like you might have a few problem interior light might be the door switch but the lock n unlock can be a fuse if they dont work in the truck or need to chance the battery in your remote

my 06 tahoe just got this problem...all other doors lock and unlock with the fab and door switch...but the hatch is in permanent locked mode. i cant even unlock the hatch window. why is this happening?

First, on the rear hatch, there is an actuator. On FX, when you close the trunk, it kind of **** the hatch closed all the way. When you press lock on the remote, this same actuator locks it as well.
Now,
1) when you unlock the car from the inside, go back there and press the button to open the hatch door manually, do you here any noises?
2) Close all doors, go back close to the hatch button and using the remote , lock the car and then unlock the car. you should hear a sound from the actuator locking and unlocking the lock on the rear hatch!

If you don't hear this, your actuator is inop.
Next step would be to check the fuses inside the car, on the left bottom driver side, and outside on the battery compartment.
It might be just a fuse.
If all fuses check ok, your actuator is most likely gone! Not ea expensive fix, just time consuming!

NOW, if you can hear the noises, then something is either broken inside the actuator or one of the cables is loose!
Hope that helps.
Also, what year and miles on your fx?

Check the unlock mechanism for the hatch. These are controlled by an electrical motor pulling a cable. If the cable came loose you might or might not hear the click click that it makes. I would also check the fuses and relays related to the system. Usually if you can get the interior panel off all the innards are exposed. I would suggest pulling that panel off, then triggering the keyless remote and see if anything moves, that might pinpoint where it has gone bad.

the unlock or popper for the door needs to be replaced. the door should work with a key.
