The whole contraption is made up of a motor with a switch on top [that's the part which located in the trunk] and an actuator [which is located in the trunk cover].
TESTING
To test the operation in the Lincoln
1-When you open the trunk, the loop should move upward until the end of
its travel. Then it should lock.
2-Open the trunk and activate the actuator switch {push it up}. If
everything is OK, the LOOP part in the trunk should move down, reach the
bottom of the travel, click the reversing switch, move up until the top of
the travel, click the reversing switch, and so on. To check the On/Off
switch, press down the black flap on top of the switch while activating
the actuator, the whole operation should stop. Obviously, this is so the
unit stops working when the trunk is closed. If it doesn't, drill a tiny,
tiny hole underneath the flap so that you can shoot some contact cleaner.
3-When you close the trunk, it should grab the cover and pull it down
until it locks.
TROUBLESHOOTING
The main control is the black switch which sits on top of the motor. This
one controls the reversing of the current so that the loop will travel up
and down. Spray a lot of contact cleaner so the contacts will work.
This is the trouble spot which causes all the problems. According to Ford, the
motor and the actuator are rarely replaced.
Don't try to open it, the spring which controls the little switch is
impossible to install once it has popped out of its place.
