2007 escalade 2 front doors wont trigger dome light but rear 2 doors do? Also killing battery on vehicle, I suspect maybe radio stays on due to vehicle not knowing driver left vehicle.

Door ajar switches maybe bad . Take the door panel off ,find a wiring diagram an test the circuit . Or you could check at the BCM ,would still need wiring diagram so you know what wire is what . Do you know how to test electrical circuits using a DVOM - digital volt ohm meter ? Could also take it to a qualified repair shop an have the BCM checked for DTC'S - diagnostic trouble codes .
The BCM, the door switches, and the liftgate module (LGM) (if equipped with power liftgate) communicate through the GMLAN serial data circuit for the lamp illumination commands of the doors, liftgate, and liftglass open/ajar switch signals. The LGM receives a ground signal from the pawl switch, ratchet switch, and liftglass ajar switch that are located within the liftgate latch and liftglass latch. For all vehicles, the left and right rear door latch switches are both on one circuit that is also an input to the BCM.
If the vehicle has a manual liftgate, there is an input circuit from the liftgate latch switch and liftglass latch switch directly to the BCM.
The left and right front door courtesy lamps receive voltage and ground from the driver door switch and the passenger door switch respectively. The remaining courtesy lamps are controlled and receive voltage through the BCM from the CTSY fuse in the instrument panel fuse block.

My liftgate ajar warning light comes on after car is started. however liftgate is latched. any ideas?

try rolling down a window or leaving a door open, shut liftgate hard. see if it still shows liftgate ajar. on my explorer the seals in door and windows shut so tightly that it was almost impossible to get the gate closed completely with doors closed and windows up.

if this doesn't help then you might need a new switch on it.

Principles of Operation
The power liftgate is controlled by the power liftgate module.
The power liftgate module receives inputs from:
  • glass position switch (determines the ajar status of the liftgate glass).
  • forkbolt switch (determines the primary position of the latch).
  • detent switch (determines the secondary position of the latch).
  • home switch (determines the power cinch status).
  • power liftgate control switch (activates the power liftgate from the interior of vehicle).
  • pinch strip switches (determines if an obstacle is detected between the pinch strip and liftgate).
  • instrument cluster module (activates and sets the options for the power liftgate).
  • optical sensor (determines the direction, travel speed and obstacle detection of the liftgate).
  • UBP serial communication link.
The power liftgate module sends outputs to:
  • liftgate motors.
  • power cinching latch system.
  • liftgate chime module.
  • body security module

The liftgate consists of the following components:
  • liftgate window glass latch
  • door lock actuator (power liftgate only)
  • liftgate latch
  • liftgate handle
  • liftgate latch remote control (power liftgate only)
  • liftgate ajar switch
  • chime module (power liftgate only)

Liftgate ajar is on

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.

the problem is the lift-gate ajar/courtesy light switch that is located on the left and right latch assemble of the lift gate, they stick and cause this concern, there are numerous technical service bulletins from Ford about this, have replaced at least 100. PS, washing the engine had nothing to do with it, u can try using spray lube on the latch's and open and close the gate repeatably to see if the switch un-sticks.
