Trunk lid pulldown motor isn't working

have you checked if getting power ? the fuse will be with the others under the dash and the fuse box cover should give a list of what fuse is what,if fuse ok check the wiring from the motor backwards and make sure the earth wire is securely fixed to the chassis/bady

There is a switch near the latch thats attached to the body of the car. It connects directly to the motor for the latch. This is the number one cause of this problem.
You could check the motor operation by removing the switch (1 Torx screw & pull it up). Then connecting 12 volt leads to the 2 contacts on the motor itself. One way it should move up the other it should go down. The 3 wire connector has both positive and negative 12 volts. The polarity switches from the position of the switch on the trunk lid by the latch.
The switch is about $30 on eBay and the switch and motor are about $150. Search for trunk pulldown switch for availability and pictures.

Do you mean the pulldown is not working, or the trunk lid latch is not connecting to the pulldown assembly when you try to close the trunk?

This latter case typically happens when someone slams the trunk lid down several times not realizing there is a pulldown system and thinking slamming it will make it close (this often breaks something). Check the latch on the trunk lid - if it's in the closed position, use the key to try to move it to the open position and try gently closing the lid again.

If not, there is also a switch on the pulldown assembly that starts the pulldown motor when it is depressed by the closing trunk lid - you can also check this to make sure it's working. Otherwise, either the latch or the pulldown assembly has been bent/broken.

replace the motor. it only cost a few buck at a junkyard. had same proble. only took a few minutes to fix

If you have automatic pulldown watch your fingers. If you hear the pulldown working the motor is good. If not the striker needs adjusting or the motor is bad.
Check the edges of your weatherstripping and if the hinges are rubbing inside the trunk.

If you have a manual setup look under the lid to see if the striker is loose and adjust. Sometimes the part in the trunk is the adjustable side.

Replace thr pulldown switch .

I had this problem on my 2005 s type.The problem was the valet switch in the glove box was in the lock position.i pressed it ,and now it works fine.Try this..

i had the same problem, there is a stop switch that is bad. (got one from a junkyard but it was bad also). haven't found one online yet, but will ask my local ford dealer if part is still available.
so untill i find one, i got the motor to stop at the all the way down position (trunk closed) and then unpluged the motor.

did it quit making the noise when you lightly push down on the trunk? most people slam these trunks and your not suppose to you are only to put light pressure on them and they pull it closed theirself.. you might check your relays under the hood and look in the box lid to see which one it is.. if this is not the problem you might have to replace the motor to the latch .. you might check with a test light to see if there is power to the motor first though .. thanks and holler if you have more Jerry .

Ok, you have an auto trunk opener/pulldown. The battery is dead and you opened the trunk with key. SO, now here is what happened. The trunk pulldown motor and latch did not go up as it normally does, in order to catch the the trunk lid as you close it. Connect a battery charger to the battery or put jumper cables on with another car. It should raise. If not flip the little lever on the BLACK switch near pull down latch.
