Year, make and model would help.
when my 89 mighty max did this I had to push the tailgate in while I opened the handle. Once open adjust or graphite the connections
To open the tailgate you have to use the key in the tailgate lock. If it is like mine, it does not always release immediately and you just need to push on the tailgate while the key is turned. You should be able to hear the latch release and then you just lift the tailgate up. If the shock absorbers for it are worn out it will be a slow hard lift to get it to open completely. l
make sure the tailgate is unlocked. while squeezing the release handle, push HARD on the bottom center of the tailgate, just above the bumper. then pull the gate out. this has never failed me and ive seen it about 50 times. once you get it open, replace the latch and the handle. they almost always need both.
1. Open the tailgate.2. Remove the two Phillips screws from the base of the tailgate handle.3. Remove the small plastic cover located on the panel, at the base of window, four inches from the center.4. Remove the Phillips screw attaching the metal tab to the tailgate.5. While facing into the vehicle, grasp the base of the handle, and pull down-and-away; the handle should pop out of the tab-slot.6. The panel is held onto the vehicle by a series of plastic retainer tabs. Start at the top and work your way around as follows:7. While sitting on the tailgate and reaching up to the outside edge of the panel, pry away the four tabs placed equidistant across the top.8. Again working from the outside edge, pry away the two side tabs located about a foot below the top of the window.9. Open the rear window.10. Slide the entire panel up-and-front. The remaining tabs will all slide up, freeing the panel from the tailgate.
The tailgate on a 2004 Dodge Ram pickup can be removed by removing the gate from the hinges holding it in place. Open the tailgate halfway and remove the slotted hinge from each side while holding the gate up. Then open the tailgate all the way and slide the tailgate off.
its locked while window is down.
If the tailgate is dropped hard it can toggle the locking mechanism. If you don't have a key to unlock the tailgate, you'll have to remove the plastic side of the tailgate (the inside) and flip the locking lever back to the unlocked position. While you have the cover off you might as well put some drops of oil on all of the metal moving parts inside the tailgate.
I assume that the latch is broken? You can get a stiff wire and poke it in the hole on the right inside section of the handle - hook the release lever and pull down while pulling outward. If this doesn't work or the hole is blocked by part of the handle, then you'll have to pull the paneling off from the inside. Look on the Toyota Sequoia boards - there are tons of explanations on how to do this and some even provide pictures. You probably will need to replace the rear handle - not that hard a job. The dealer wanted $400; I did it for $15 with an eBay knockoff.
Have a helper pull the release handle while you look at the release mechanism. This will tell you if the cable is broken or if the problem is in the trunk mechanism.
While pulling on the handle as if to open the hatch, take a screw driver and pop the locking mechanism/latch to the open position. It should work no problem.
If the damage is minimal then try and remove the door panel so you can access the internal workings of the door and try to get the catch mechanism to release that way. Hope This Helps. Pulled from: http://answers.yahoo.com/question/index?qid=20071001131029AAvU8LI&show=7 Don't hit it or kick it or push it or pull it...this is an easy one! When you pull up on your handle, these two arms on the handle in turn push two levers, one lever will pull on the right side rod and the other lever will pull on the left rod. After time these levers start to get bent out of shape from use. Eventually, when you pull up on your handle to open your tailgate usually one of the levers is so bent that is doesn't fully pull the rod enough to release the latch. One side might release but not the other. So here's what you do---lift up on the handle about halfways and look up under there. You can see where the two rods (the ends are in an 'L' shape) are inserted into plastic nuts. You can now see when you lift up the handle all the way which rod isn't getting pulled on---the one with the least movement. Those plastic rod clips clip onto the shaft of the rod after the tip of the rod is inserted into it. Let's first release the clips---Get a long flat-bladed screwdriver and position it under the part of the clip that is on the shaft. Pry up on it until it releases from the shaft. You can now push the 'L' shaped part of the rod out of the clip. Do that to the other clip also, although you might have to pry down on the clip to release it then remove the 'L' shaped end from the clip. Now you can manually pull the 'L' shaped ends of the rods towards each other to release the latches. Maybe a pair of pliers or needle-nosed pliers would be easier. Pushing on the tailgate to relieve the pressure on the latches may make it easier to pull on the rods too. You can also release one side at a time to open it. Once opened you can take the bent handle off of the tailgate and try to reposition the bent parts (which works a lot of the times) or just replace it. Just remove the three bolts on the inside of the tailgate and wiggle the handle out. Maybe hold the handle in the open position while removing it might help. Then you can operate the handle and see where everything makes contact with each other and see if you can put things back in the position they were supposed to be. When all is said and done be sure to WD-40 everything!!! Hope this helps best of luck.
Bang the hood above the latch while someone pulls the hood release from in the car. Good luck.
