Why do I see a rear access open and a gate ajar warning on insument panel, even though it is locked?

Unless you have electrical diagnostic skills , I suggest you take this to the dealer ! The lift gate can be opened by operating the switch on the instrument panel. Battery voltage is supplied to the liftgate actuator through the body control module (BCM). The BCM will pulse the lift gate actuator when a release input is received through the key fob, or the instrument panel switch.
The body control module (BCM) receives an input from the liftgate ajar assembly. The ajar assembly is normally open when the liftgate is fully closed. When the liftgate is opened, the ajar assembly contacts close providing a path to ground. The driver information center (DIC) illuminates the rear access open message when the gate is open. The instrument panel cluster (IPC) receives a serial data message from the BCM indicating the liftgate ajar status. If this message is displayed and the vehicle speed is greater than 8 km/h (5 mph), a chime will sound.
It could be ajar switch is bad .

Not sure what your talking about . There is no sensor. there is a relay in the I/P fuse box LIFTGATE PCB relay . an a lift gate actuator motor inside the door . An there is a door ajar switch ,which is part of the latch mechanism. Do you have light lit on the instrument cluster - a picture of a little car with a door open , an maybe a chime sounding ?

Not

Access the gate latch from the inside by removing the interior door panel. Once the gate is open, replace the actuator and you should be good to go.

I have a 2008 Suburban with the power liftgate disabled. I have had the power latch stop working, and the BCM report that the rear access open when it is closed (both gate and glass). Somehow the liftgate module thinks the gate is open, so I cannot open the gate at all, and the latch and rear wiper will not work. To reset the control module I pulled the liftgate fuse (#20) in the instrument panel fuse box, turned the car on, off, reinstalled fuse, turned car on, unlocked doors using drivers side switch, and the power latch will function again - at least for a while.

Hotnurse37. I'd you fix your problem. I have same issue. Fuse is okay. Remote will open all doors but I can't even hear the rear attempting to unlock. Did get access to emergency release after trying for a long time. Lock and latch looked fine but back to same problem after closing lift.

your rear glass on your tail gate is ajar ..press the round circle button on the gate from the outside and the glass will pop open at yah close the glass a little harder since the latch is a bugger to catch i get this all time with mine

and your rear access msg will disappear and your rear windshild motor may work since the glass isnt fully closed the wiper wont run

good luck

how to i open a stuck lift garte on a ford winstar 2000 lock broken too

I have a 1999 Chrysler T&C 3.8 liter like yours and it sounds
like you are having the same the same problem I had.
Every time you hit the door unlock or lock button, it made a loud
buzz like you just missed a question on a game show. ;-)

It turned out the problem was the rear lift gate lock actuator. The part costs
about $40 from the dealer if I can recall correctly.

The repair involves: 1st removing the middle and rear seats to get
access from the inside to the rear gate
(obviously you will have to remove the seats from the side doors
since the rear gate won't open yet)

Remove the plastic inside rear gate panel and molding (phillips screws)
Once you remove the panel, you may see a way to manually
open the rear gate. As I recall, I think there was a access opening
covered from the inside with a black weather/insulation tape.
Carefully removing this out of the way gave access to a way to
manually open the gate, making the rest of the work easy.

Remove the electrical connector and the mounting bolts
to remove from the actuator. It is attached to the inside
rear gate with 2 or 3 bolts (10 mm?)

Remove the old one and replace the part, then put it all back
together, make sure you reconnect the electrical connector

Takes about an hour for the whole job (max)

Hope this helps,

there should be a switch mounted( or more than one) in the door jamb that tells the car when the car door is open...i will probably look like a little plastic plunger...might be broken off or bad internally

There are 2 switchs one each for the left and right liftgate latch, u must detrim the liftgate to replace them, they stick and cause your problem, replace the courtesy light switches on both latches.
