2004 lincoln navigator lift gate open warning comes on with lift gate closed.


liftgate ajar switch , possibly . Without testing that would be just a guess . Do you know how to test automotive electrical circuit's ? Using a wiring diagram an a DVOM -digital volt ohm meter ? Looking at a factory service repair manual to find location of the ajar switch . Also checking for DTC- diagnostic trouble codes ,first !
B2703 Open/Close Switch Stuck Active Power Liftgate Module B2721 Gate Ajar Output Short to Ground or Open Power Liftgate Module REFER to Section 501-03 . B2722 Open/Close Switch Active During Self-Test Power Liftgate Module REFER to Section 501-03 .

The tailgate on my 2007 Surburban will start to open when you touch auto open then closes once halfway open


Probably a sensor ! without hooking up a factory scanner an checking for DTC'S - diagnostic trouble code's couldn't say for sure what the problem is . Your best bet ,take it to a qualified repair shop .
Electronic module involved in the operation of the liftgate .
Object Obstruction Detection
The liftgate control module continuously monitors power liftgate operation and calculates its location and direction of travel using 2 hall effect sensors that are part of the gear motor assembly. The hall effect sensors are 3 wire sensors and are supplied with a 5 volt power circuit, ground and signal circuits from the liftgate control module. The hall effect sensor signal circuits are referenced from battery voltage within the liftgate control module and pulsed low by the hall effect sensors.
The power liftgate system uses a secondary object detection method which consists of object sensors fixed to both sides of the liftgate near the seal area. The object sensors consist of an internal fixed resistor and normally open switch contacts which when closed will bypass the resistor. The signal circuit is supplied 5 volts through a resistor and monitored within the liftgate control module, and during normal power liftgate operation the signal circuit should remain a fixed value. When an object presses one of the sensors the contacts close and the resistor is bypassed causing the signal circuit voltage at the module to go low.

2008 Cadillac srx power tailgate opens fine, but won't close with the remote. I can't hear the motor. The auto close button doesn't work either. Is there a fuse or relay? If so where is it?


An electronic control module controls it .
The liftgate module (LGM) controls operation of the liftgate latch motor and the liftgate actuator assembly. Do you have a Liftgate Ajar Indicator ON ? Or a message in the message center driver information center (DIC) illuminates the LIFT GATE AJAR indicator ? The liftgate control module could have a DTC - diagnostic trouble code in memory !

When open, the liftgate can be closed by either a keyless entry transmitter or the liftgate close switch. When a GMLAN serial data message or switch input is seen, the liftgate module begins the close sequence. The liftgate motor is reversed, lowering the liftgate until it latches into the liftgate latch. Once latched, the latch will cinch the liftgate to a fully closed position.
Power liftgate function will only be allowed if certain operating criteria are met. Any of the following may cause the power liftgate not to function:
?€¢ Vehicle is not in park. ?€¢ Engine cranking is present. ?€¢ Temperature limits have been exceeded. ?€¢ Liftgate motor overcurrent is detected. ?€¢ Excessive hall effect counts are seen. ?€¢ System voltage is out of range. ?€¢ A DTC is set that disables power liftgate functionality. The liftgate also receives inputs from 2 object detection sensors. If either of these sensors indicate an object is in the path of the liftgate, liftgate functions will be suspended until the object is removed.

The rear lift gate on my 2006 Lincoln Navigator will not open automatically or manually and there appears to be no way to access anything inside the door from inside or out.


POWER LIFT-GATE OPERATION - To open the optional power liftgate, push the button on the instrument panel , press on your five-button key fob (if equipped), or press and release the control located in the left rear quarter panel (Figure B). To unlatch the liftgate glass, push the button ) under the center of the license plate lamp shield, or press on your five-button key fob. Do not open the liftgate or the liftgate glass in a garage or other enclosed area with a low ceiling. Keep clear of the liftgate when operating the rear switch. To open the liftgate manually, pull the handle located on the liftgate to release the liftgate from the vehicle. The power system will take over when you release the handle. To close, make certain the rear window is closed, and then pull down the liftgate a few inches to activate power closing. Closing the gate rapidly or more than a few inches may activate the obstacle detection feature and stop the power system.------------ Also click this link for more help:--- http://technoanswers.blogspot.com/2011/05/power-liftgate-on-will-not-open-on.html ------------ This should help.Keep updated.Thanks.Helpmech.

My rear lift gate on 07 tahoe opens and closes its self weather the key is in the ignition or not, opens 1/2 way closes 3/4 then all the way up and all the way down, sometimes it sets off the car alarm- it...


Operation
A power open or close cycle can only be initiated from the fully closed or open positions while the vehicle is in park and the liftglass ajar switch input to the liftgate module is inactive. At any time during a power open or close cycle the operation can be reversed by pressing any of the open/close switches. The power liftgate can be switched to manual mode with the on/off switch in the overhead console and during manual operation the power latch will still operate. During power liftgate operation the liftgate module continuously monitors the liftgate position and load profile. The position is calculated from hall effect sensor counts and the electrical load of the gear motor is used to determine physical resistance to the liftgate. Both of these profiles must be learned before the liftgate can operate properly and relearned any time most liftgate components are serviced.


Object Obstruction Detection
The liftgate control module continuously monitors power liftgate operation and calculates its location and direction of travel using 2 hall effect sensors that are part of the gear motor assembly. The hall effect sensors are 3 wire sensors and are supplied with a 5 volt power circuit, ground and signal circuits from the liftgate control module. The hall effect sensor signal circuits are referenced from battery voltage within the liftgate control module and pulsed low by the hall effect sensors.
The power liftgate system uses a secondary object detection method which consists of object sensors fixed to both sides of the liftgate near the seal area. The object sensors consist of an internal fixed resistor and normally open switch contacts which when closed will bypass the resistor. The signal circuit is supplied 5 volts through a resistor and monitored within the liftgate control module, and during normal power liftgate operation the signal circuit should remain a fixed value. When an object presses one of the sensors the contacts close and the resistor is bypassed causing the signal circuit voltage at the module to go low.

Gear Motor Assembly
The liftgate motor is a bi-directional motor and open or close operation is the result of the direction of the motor rotation. The liftgate module controls the liftgate motor through the control circuits by suppling power and ground in the appropriate polarity. The motor control circuits are monitored by the liftgate module prior to activation for a high or low condition and during motor operation for any irregular current flow conditions.
The liftgate motor clutch engages or disengages the liftgate motor to the liftgate drive gear and is the component that determines power or manual operation. When the liftgate module supplies power to the clutch control circuit the clutch coil is energized and the liftgate motor is engaged to the liftgate drive gear so that power operation can occur. The liftgate module monitors the clutch control circuit at all times for a short high while in an inactive state or a short low or insufficient current flow while in an active state.
The full open switch is part of the gear motor assembly and will close and become active when the liftgate reaches the full open position. The full open switch signal circuit is supplied battery voltage through a resistor and monitored within the liftgate module. The liftgate provides a low reference circuit and when the switch contacts close the signal circuit goes low and the liftgate module determines the switch to be active.

My passenger's door open indicator is on but the door is closed. Where is the indicator located? 2005 freestar. Thanks


Normal Operation When any door or the liftgate is opened, the ajar switch provides a ground signal to the smart junction box (SJB). When the door or liftgate is closed, the ajar switch opens, removing the ground signal. The SJB uses the multiple inputs from the ajar switches to determine whether the doors or the liftgate are in the open or closed position. The SJB then provides a message to the instrument cluster over the communication network. The message center uses this information to display the door/liftgate ajar message.

I suspect your door switch is not closing all the way.
