Fix a Ford trunk won’t lock condition
Ford has issued a service bulletin #10-5-9 to address an issue where Ford trunk won’t lock on the vehicles listed below. In these cases, you can slam the trunk but the trunk won’t lock.
The bulletin applies to these Ford vehicles where the trunk latch solenoid is stuck open and Ford trunk won’t lock.

Ford states that the problem is caused by an inoperative trunk lid latch solenoid. To confirm this is the problem, Ford recommends the following test procedure:
1: With the trunk lid open, turn the key to the ACC position. Then cycle the trunk lid release button in the passenger cabin. After hearing the latch operate, try closing the trunk lid. If the trunk lid closes and locks, this bulletin doesn’t apply. If it doesn’t close and lock, proceed.
2) Check to make sure the electrical connector is securely fastened to the latch assembly and that the emergency T-handle release is routed correctly.
3) If everything appears normal, replace the latch
