I have 2004 and the back hatch will not open,only use remote control to open ok,before I can manual open don';t need use remote control.

Found this wiring diagram for lift gate, if that is what we're talking about? Not only check the fuses, check fuse circuit for voltage. Use a testlite.

latch and lock are jammed from the hit will probably need to pry hatch over or lift while unlocking to open than adjust hatch or latch for proper working order also check relay and fuse hit may have also damaged wiring

Either the battery is low on the remote controller unit or a fuse has blown in your fuse box to stop them all opening .
Contact a local dealer they may have an idea as you are probably not the only one for this to happen to..

Is it the back hatch? Can you pull the rod on the broke side & pull handle at the same time?

You could have a bad Lift Gate Module (LGM) or a broken wire in the wire harness going thru the rubber boot between the body and the lift gate.
But first check fuse #19 in the rear fuse panel.

Did these doors quit at the same time or over a period. It seems that the actuators for the locks have gone bad. With the mentioned doors, that's a lot weight for the actuators to unlock and pop open. With the remotes and console not working , that's more reason to think the actuators are the problem.

I have a problem the back door will not open with key remote or just by the touch pad. That I know of is there a release button or something to open the back hatch.

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?

This is due to the microswitch inside the glass hatch failing. It will not let you open the door because it is unsure if the glass is open or not.

Here is how to verify this:

Manually open the glass hatch.
Remove the two philips screws from the cover on the back of the handle area, and unscrew the plastic plug with the slot in it.
You should now be able to remove the cover.
You will see the harness coming off the glass handle going to a connector. Unplug this white two wire connector.
Your rear hatch should now open normally, just without glass opening.

To repair this, you will need to replace the glass hatch handle. It is a dealer-only part, and the cost is about $35.

To replace it, simply remove the 2 10mm nuts behind it (visible with the cover off that you just removed) and replace the handle and plug it back in.
Now all functions will work.

If you have any questions, just ask :)
