Check the following fuses;
Underhood fuse panel - fuse #31
Rear fuse panel - fuse #4, #7, #31, # 32 & #40

All these have to do with the Body Control Module (BCM)

2008 explorer door locks not locking from door switches


This is not a good thing. Ford uses a computer called the GEM and that means General Electronics Module. It controls:
  • Low Coolant Indicator On Cluster
  • Brake Indicator on Cluster
  • DRL - Control
  • Wipers
  • AutoLamps
  • Rear Defrost
  • Interior Lamps(dome)
  • High Beam Indicator only (cluster)
  • Low Coolant indicator
  • Key-in Buzzer
  • Seatbelt indicator only (Cluster)
  • Trunk Pop Relay
  • Power Locks
  • Door Ajar Sensors
  • Door Keyless entry pad
  • Remote Keyless Entry
  • One Touch Down (power window)
  • Air Bag Tone
  • Anti Theft (perimeter Alarm) (SEL, or SE(s) with mods)
  • Lift gate ajar (wagon)
  • Liftgate Pop
  • Accessory Delay signal (accessory that work after engine off, prior to door ajar)
  • Battery Saver Relay signal (accessory that work after engine off, 15 mins) Map lights, vanity mirrors

They are located behind the radio in the dash and they are $$$ about 600 USD.

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 .

97 grand cherokee limited power windows mirrors and locks wont work but passanger side will go up using that side control


  • If you open the drivers door and take notice of that harness that stretches between the door frame and the door. If their is a boot slide it to one side and then the other side and if their is no boot slice the harness open lengthwise.

  • What your looking at is the wires in that harness. Them wires are the power feed (and ground) for the different electronics inside the cabin ie door lock, chimes, windows, dome lights, etc. Look for split, pinched, bulging, rusted wires or wires with negated insulation. Splice a new wire into the area where the wire[s] are broke off and re-insulate.

  • This is a common problem with most vehicles across the board. Over time, due to placement of the harness, the wires begin to crack and dry out and get pinched. Broken wires is almost always the problem with a problem such as yours.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

The dome light and cabin lights do not work. I checked fuses and bulbs and all are fine.


The cable that supplies power to these points is either loose/disconected or has corosion. Trace the wire to the main loom down to where it gets power from the main power supply.

POWER LOCKS,WINDOWS NOT WORKING.DIMMER LIGHT SWITCH IN ANY POSITION BRINGS CABIN LIGHT ON AND STAYS ON....FOREVER!


That sounds to me like your door trigger wire or trigger is bad. Look for some kind of button that gets pressed inside when the door closes. Often times door driggers only have 1 wire which may rest at power OR ground and sends the opposite signal when the door closes in turn causing your dome light to turn on/chime to ring. I'm making the assumption that the lock wont work because the vehicle thinks the door is open. Just my electrical theory.
