The indicator for park/neutral is changing on the dash without you moving the shifter?
If so...the park/neutral switch on the transmission...(or could be on shifter housing) is informing the lock control module/body module... that the vehicle has been put in park...thus the door unlock actuation...then..apparently the switch is erroneously informing the lock module that it is in neutral...drive...thus locking the doors....could also be a fault in the general body module...which ..most likely...controls most of the body systems via CAN BUS....Controller Area Network system....
Odd that no codes are in the body/lock module....make sure your scan tool is indeed able to access the body control systems...if not...you need to find a location that will provide that service.

make sure than you have not split any fluids on the passenger front door most of the times is where the module to control the windows and doors is located, try by unpluging the batterie and the after a minute plug it back and see what happend but if any of your ft doors have been split with liquid or rain has gone inside then most likelly the module got moisture and not working

Check battery voltage. if above 13.7 volts move to rear lock actuator and measure battery voltage at actuator if above 13.6
replace actuator if below specs. check grounds and alternator out put as follows, alternator output 13.7 to 14.25 volts. key off battery volts should be 12.90 + - 3/10 of a volt and about the same voltage at the actuator. let me know. kindest regards Bill

you will need to remove the door panel to get to the actuator, there is probably a clip that has either broken or popped out

there is a relay but if it were bad none of your locks would work. your problem is the door lock motor it is a little electric motor that actuates the lock. its also called a door lock actuator. kind of expensive and a little difficult to replace.

I locked my 2003 GMC envoy but key won't open doors my passenger door slightly able to open it s there a way to pop lock


Will they open with your remote? If not, there is probably a problem with the doors locking/unlocking system. If you can get the rear hatch open, best bet is to crawl in from there and unlock a door manually. At that point you can check if any of the door switches are working. Otherwise, best bet is to use a locksmith to get into the truck.

2003 gmc envoy keyless entry is locked and will not unlock with the key or the remote. it does lock - horn and lights illuminate. is it the remote or the car? I can't even unlock to pop the hood.


if your key is not working to unlock door==try turning key over and then try to unlock door. I have had keys made for replacements and they sometimes don't work quite right one way but work just fine the other way.

to unlock hood with out being able to get inside; you need to reach up from under car and pull/yank on cable to unlock hood.

2009 GMC Envoy - power door locks, power windows, fuel gauge not working, dome light isn't working


Do you know anything about automotive electronic's ? computer controlled systems ? There is electronic control modules in side the doors of your vehicle that control the operation of the windows an lock's , plus the instrument cluster is a module too . Your vehicle has about 10 different control modules and thet are all hooked on a serial data communication network ,to share info. The fuel tank sending unit in the gas tank is wired to the PCM - engine computer , The PCM sends fuel level info to the gauge in the instrument cluster on this serial data network . Your best bet ,take an have the vehicle checked out by a qualified repair shop .
The power door lock system consists of the following components:
• Driver Door Module (DDM)
• Passenger Door Module (PDM)
• Liftgate Module (LGM)
• Door lock relay
• Door unlock relay
• Body Control Module (BCM)
• Reversible door lock actuators in each of the doors
• LR/RR LOCKS 10A fuse (relay supply voltage)
• Door lock switches in driver and passenger doors (switches are integral components to the DDM and PDM)

Power Door Lock Operation
The power door lock switches are integral components of the DDM and PDM. The switches are two position normally open rocker switches. When placed in either the lock or unlock positions, the switches provide a direct input to the DDM or PDM. The DDM or PDM monitors these inputs and sends a Class 2 message indicating a change in the switch's respective position. Modules which activate the power door lock motors receive the Class 2 message and activate the motor in the appropriate direction to lock or unlock the vehicle's doors and liftgate. The modules which activate the power lock motors are:
• DDM (driver door lock actuator).
• PDM (passenger front door lock actuator).
• BCM (both rear door lock actuators).
• LGM (liftgate door lock actuator).
The DDM, PDM and LGM are directly connected to the respective door lock actuator through the door lock motor lock and unlock circuits. Once a door lock or unlock request has been received, the module will supply battery voltage to one side of the actuator and ground the other causing the doors to lock or unlock.

The modules probably have DTC'S - diagnostic trouble codes stored , these would point a auto tech in a positive diagnostic direction .
