Electronic's , aren't they great ? There is a control module (power lift gate module ) Switch (sensor) inputs to the module . Lift gate obstacle detection strip right and left , liftgate cinching motor ,liftgate unlatch motor .Liftgate drive motor assemblys left and right . Probably a bad switch feeding bad voltage signal to the control module ! Like one of the obstacle detection sensors maybe. Could possibly have DTC'S - diagnostic trouble codes stored in the control module. Your best bet maybe to have the dealer run diagnostic's on it , check for codes . Need a factory or professional type diagnostic tool to do this. I would say you mite be able to check the sensor inputs to the module , don't know what or how much voltage > Some of these circuit's are a five volt signal from the module . Ohm check the obstacle detection sensor ? I still think best thing would have it checked for DTC'S . Almost forgot about the thing opening when you close another door , All the modules on the vehicle are connected on what is call a serial data network . Doors have modules inside as well .could be commanding that door open some how.
If you would like to see what your up against , here is a web site for free wiring diagrams http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size. Under system click on body & accessories , then under subsystem click on power liftgate. Click the search button ,then the blue link. The second diagram down starts liftgate diagrams . Good luck !
Do you know how a O2 sensor works ? Do you know what fuel trims are ? short an long term fuel trims . Do you know how to test a O2 sensor . If the light comes back on it's not the O2 sensor . And if it's only on one bank it's not fuel pressure problem . How does the vehicle run , at idle an cruise ? Any other codes ? Could be a fuel injector problem , vacuum leak intake manifold .
Most likely yes. It takes an experienced Parts guy to look up the interchange. Ford part numbers had a sequence that stated the model and year first, the base part number, and whether it was a left or right sided part. Your Lincoln parts most likely have a premium price but are often no different than a Ford part. Some exceptions can occur in things like optional transmissions and 4 wheel drive that may make different muffler and catalytic combinations that a Ford may not be equipped with. The part number will be different but it probably is the same part.
You could have a shifter interlocker system problem !
Shift Interlock System
The shift interlock system prevents the shifting from PARK unless the brake pedal is depressed. The shift interlock system consists of a shift lock actuator mounted at the base of the steering column or on the floor shifter mechanism. If the ignition switch is in the RUN position, the shift lock actuator is on unless the brake pedal is depressed.
Inspection and Verification
Verify the customer concern by operating the transmission external control.
Visually inspect for obvious signs of mechanical and electrical damage; refer to the following chart:

Damaged shift lock actuator
Damaged transmission control switch
Failed fuse(s)
Damaged wiring harness
Loose or corroded connections
If the fault is not visually evident, determine the symptom. GO to Symptom Chart .

Take the vehicle an have it hooked up to a professional type scan tool that will communicate with all the computers on the vehicle !
If these lights are on 6.The Advence traction light is on
7. the Anti-lock ABS light is ON - there are codes stored in thier control modules . All the things your have trouble with have a control module incharge . That is except the lighter . I will tell you honestly your best bet mite be to take your vehicle to a qualified repair shop ! Dealer . You have no idea of the complexity of your vehicle . All the computers , serial data network . How the computers share info on said data network . Do you know how to use a DVOM . digital volt ohm meter ? how to read a wiring diagram ? How to find wiring diagrams . No one on here is going to give you a magical fix . Looking at wiring diagrams for the problem componets , seeing if they share a common power source or ground point . Testing electrical circuits . I would say you probably have no clue as to how thesee different systems function . I ECM Inputs and Outputs DiagnosisVoltage Drop Essentials TST Motor AgeElectric Testing Techniques You Need to Know
