Trunk and hood manual latch won't work

To open the hood of a 2004 Chrysler Pacifica with a dead battery, try these steps:
Find hood release lever: Usually located on left side of driver's footwell near the hood release cable.
Jump-start battery: Connect battery to another car's battery if it's completely dead. This will provide enough power to release the hood latch.
Use manual release: If jump-starting is not possible, consult owner's manual for manual release location.
Get help: If unsuccessful, call for help from a tow truck or mechanic.
Caution: Make sure the car is in park, emergency brake is engaged and engine is off before opening the hood.

There could be several reasons why the trunk of your 2004 Mercedes-Benz S500 will not open. Here are a few things you can try:

1. Check the latch: Make sure the latch is not stuck or damaged. You can try lubricating the latch with penetrating oil or WD-40, or gently prying it open with a flat tool like a screwdriver.
2. Check the trunk release button: If the trunk release button is not working, it may be due to a problem with the electrical system or a faulty trunk release switch. You can try replacing the fuse for the trunk release or checking the switch for any visible damage.
3. Check the key: If you are using a key to unlock the trunk, make sure the key is not damaged or worn out. You may need to have the key replaced if it is no longer functioning properly.
4. Check the trunk lock: If the trunk lock is stuck or damaged, it may be preventing the trunk from opening. You can try lubricating the lock with penetrating oil or WD-40, or have a locksmith inspect and repair the lock.

If you have tried these steps and the trunk is still not opening, it is possible that there is a problem with the trunk mechanism itself. In this case, it is recommended to have the car inspected by a mechanic. They will be able to diagnose the problem and recommend the appropriate repairs.

A trunk lid is secured into position using a latch and striker similar to those used for the hood and doors. The striker is a U-shaped piece of metal fixed to the trunk lid. The latch is a mechanism that hooks around striker and holds it tightly until the latch release lever is pulled. Latch release levers can be actuated electronically via a solenoid and switch or mechanically via a cable and handle. The most common failure item with electronic systems is the solenoid actuator which is typically integrated into the latch itself. For manual release systems the most common failure items is the cable which tends to snap internally, especially if there is a problem with the latch such as binding. Accessing the trunk area to replace the necessary parts can be tricky if the trunk won't open; in these cases I'd recommend trying to open the trunk with the key (if it has a lock cylinder) otherwise the back seats will need to be laid down or removed in order to get to gain access.

• Press down on your trunk, and have somebody release your trunk's release mechanism from inside your car simultaneously. These systems can become jammed but can sometimes be released if a gentle downward pressure is applied to your trunk while the mechanism is being activated. If this is the problem, apply some lubricant.
• Clean the latch and the area where it connects to the chassis. If dirt or debris has become lodged here, it can stop the latch from connecting properly. It's a good idea to vacuum the area to ensure no small bits of gravel have become trapped and stopped the mechanism from securing properly.
• Examine the latch and the area where it connects to the body of the car. Either of these might have become bent out of shape or damaged in some other way if the trunk has been shut with an obstruction in the way. If this is the case, contact your vehicle's manufacturer or a local garage to find a replacement if the elements cannot be repaired.

Check the latch mechanism, it may have accidentally already be in the closed or lock position. If it is, you will have to pry down on the latch tangs with a screw driver while pulling latch handle to the open position.
Latch could also be seized, in that case , use a thin oil liberally on latch mechanism, and work the mechanism open and shut closing and opening with screw driver and boot handle.

How to fix trunk that won close 2006 2008 civic for less than 5

I've had this problem also. I followed the instructions exactly and nothing happened. I troubleshot the issue and I realized that the clamp on to the door latch was not making a ground connection. Try touching the ground clamp directly to the head of one of the bolts on the door latch. This worked for me and the hood opened instantly. The quality of the ground connection seems to be the key. By the way, if you do not want to use a donor battery, a battery charger will provide sufficient power to release the hood latch. Good luck!

I believe you do this in this order. Roll windows down, release the latch at the top of the windshield, raise the front of the top, release rear cover by pulling the latch near the rear seat, Pull up the back of the top and then pull up on the rear cover. The back of the top should now fit into the opening under the rear cover. Continue to fold the top into this space. Push down on the rear cover to lock (won't be able to open trunk if not engaged.) To raise it, release rear latch cover, open rear cover and pull top out of opening. Raise rear of top so you are able to now close the rear cover, set rear of top down on cover and then pull fron of top down and engage the fraont latch. Hoe that helps.

check trunk fuse

The trunk latch is operated by a solenoid which it requires power to operate. since the batery is flat then it won't work. I'm not sure where the positive terminal is under the hood but you can connect the positive lead to the alternator wire terminal, and the negative lead can be connected any where on the engine.
Good luck......

I just went through HELL because my top would not go down! I did EVERY possible solution with NO AVAIL! So anyway, Im in the trunk and noticed a baggy sack hanging in the trunk.. So I figured it was for the roof.. Anyway the sack has 2 straps to hold it up for more room when the top is UP. So I said "I Wonder...." I released the straps and the bag hung again, and GUESS WHAT? Yea the roof works!!!!!!!!!!!!!
