Not sure about a body control module, there is a pcm under the hood on the pass. side that controls most everything on these, however i would check your fuses for the seat, on the 00 models the headlights do stay on all the time while driving due to daytime running lights but if they stay on after you take the key out then id check the headlight switch or sensor on the pass side dash.

SOURCE: 2000 Saturn SL2 - replaced ignition then BCM failed. Related?

the problem is not the bcm. the passlock security sensor is in the cylinder and housing, if the cyl and or housing was replaced the system must be relearned. if you replace the bcm you still need to relearn the system or it still will not start.

Where are the fuses for the power dock locks on a 2006 montecarlo06ss


DR/LCK fuse 25 amp . located in the I/P block
Fuse Block - I/P
In the right front kick panel

Power Door Locks System Components
The power lock system consists of the following components:
• Body control module (BCM)
• Driver door lock cylinder switch
• Front passenger door lock cylinder switch
• Driver door lock switch
• Front passenger door lock switch
• Door lock actuators in each of the doors
• DR LK Fuse 20-amp
Door Lock System Controls
The Power Door Lock System is controlled by the body control module (BCM) and can be activated by any one of the following:
• A door lock switch lock or unlock actuation
• A door lock cylinder switch unlock actuation
• A keyless entry transmitter actuation
• An automatic door lock actuation (Personalization function)
• An automatic door unlock actuation (Personalization function)
Door Lock Operation
When the body control module (BCM) detects a transition of either of the door lock switches to the lock position, it switches the door lock actuator lock control circuit to voltage. Since the lock actuator unlock control circuits are at ground potential within the BCM, the door lock actuator motors transition to the lock position.
Driver Door Unlock Operation
When the body control module (BCM) detects a transition of either of the door lock switches to the unlock position, it switches the driver door lock actuator unlock control circuit to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the left front (LF) door lock actuator motor transitions to the Unlock position.
The driver door lock actuator unlock control circuit is a dedicated control circuit used only for the driver door lock actuator motor. This is done so that the driver door may be unlocked by itself using a keyless entry transmitter or an automatic door unlock function (if programmed).
Passenger Door Unlock Operation
When the body control module (BCM) detects a transition of either of the door lock switches to the unlock position, it switches the door lock actuator unlock control circuits to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the passenger door lock actuator motors transition to the unlock position.
The door lock actuator unlock control circuits are dedicated control circuits used only for the passenger door lock actuator motors. This is done so that the driver door may be unlocked separate from the passenger doors using a keyless entry transmitter or an automatic door unlock function (if programmed).

2006 GMC Envoy: I tested all of the fuses and all of them check out but my power locks, cabin lighting, dash panel lights, etc. aren't working.


Which fuse box ? Do you know what a DDM -is ? Driver door module . Do you have any idea what all is involved in making these thing's you have listed work ? A lot more then a fuse , there could be DTC'S - diagnostic trouble codes stored in the principal Control module ,the BCM , That could save a tech. valubale time in diagnoising this problem !
Door Lock System Components
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)
Did you know there is a fuse box in the rear of the vehicle ?
Fuse Block - Rear
Beneath the left rear seat
The inside lights are also controlled by the BCM , and the fuse's are also located in the rear fuse box .
The body control module (BCM) directly sends a 5-volt reference voltage to the instrument panel (I/P) dimmer switch which is then adjusted based on the I/P dimmer switch position and returned as a low reference and a signal to the BCM. The BCM uses this signal to directly control the desired level of instrument panel illumination lamp intensity.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC B2620 Display Dimming Pulse Width Modulation (PWM) Input Circuit. There are several DTC'S that can set !
DTC B3801 Passenger Compartment Lamp Request Circuit
DTC B2610 Passenger Compartment Dimming 1 Circuit plus others for power locks .

What do I replace if my Auto door locks won't work


First off testing would need to be done to determen what the cause is . The door locks on your vehicle are controlled by a computer ,BCM - body control module . The first test would be to check for DTC'S diagnostic trouble codes in the BCM . An to do this you would need a factory scan tool , not a OBD2 code reader . Door Lock System Components
The Power Door Lock System consists of the following components:
• Body control module (BCM)
• Driver door lock switch
• Front passenger door lock switch
• Reversible door lock actuator in each of the doors
• IBCM (PWR) 15-amp fuse
• Driver door cylinder switch, if equipped
Door Lock System Controls
The Power Door Lock System is controlled by the body control module (BCM) and can be activated by any one of the following:
• A door lock switch lock or unlock actuation
• A keyless entry transmitter actuation
• An automatic door lock or unlock actuation
• A last door closed locking (LDCL) actuation
If the driver door cylinder switch feature of the vehicle is functional, the locks may also be operated by a driver door cylinder switch lock or unlock activation.
Your best bet would be to take to a ASE certified repair shop or the dealer.Because if the BCM were the problem an had to be replaced , it would need programming .
Each door lock switch is wired to the body control module (BCM) through a separate door lock/unlock signal circuit. While these circuits are separated between the BCM and respective door lock switch, they are connected into a single circuit within the BCM. The BCM supplies voltage through the door lock/unlock signal circuits to each door lock switch. When either door lock switch is operated, this supply voltage is pulled to ground, providing the BCM with the required lock or unlock signal. In order for the BCM to distinguish between a lock and unlock signal, the lock switch contains two separate paths for this voltage to flow to the same body ground. When the switch is operated to the unlock position, the supply voltage flows to ground through a 1.5K ohm resistor. When the switch is operated to the lock position, the supply voltage flows to ground through a different part of the switch circuit, which has no resistor. The BCM then interprets the flow of voltage as a lock or unlock request and powers the door lock actuators to the appropriate lock or unlock position.

What causes a malfunction in power locks?


The power door locks are controlled by the BCM -body control module ! The door lock switch is an input to the BCM .
The BCM, upon receipt of a door lock switch lock or unlock signal, will switch the appropriate door lock actuator control circuits to battery positive voltage. The opposing side of the door lock actuators are connected to ground internally within the BCM through the other door lock actuator control circuit and the doors will lock or unlock appropriately.
First thing to do would be check power an ground circuits at the BCM ! Do you have any other systems not working -power windows etc...
The DR/LCK fuse supplies battery positive voltage to the I/P fuse block for the door lock system. The body control module (BCM) supplies and monitors a reference voltage to the door lock switch through the door lock switch lock/unlock signal circuit. The door lock switch also receives a constant ground source. If a door lock switch is placed in the lock position or unlock position, the reference voltage is taken directly to ground and the BCM detects the voltage drop on the signal circuit.
Should have BCM checked for stored DTC'S - diagnostic trouble codes !
Ignition ON, observe the scan tool Driver Door Lock Sw, Psgr Door Lock Sw, Driver Door Unlock Sw and Psgr Door Unlock Sw parameters while using the driver and passenger door lock switches. The parameters should change between Active and Inactive.
?‡'
If the values does not change between the commanded states, refer to Door Lock Switch Malfunction.

Command the driver door and passenger door lock actuators to LOCK and UNLOCK with the scan tool, the doors should LOCK and UNLOCK when changing between commanded states.
?‡'
If a door lock actuator does not perform the LOCK and UNLOCK functions, refer to Door Lock Malfunction

How do I program keyless entry on my 2002 grand prix? I have tried the way I found by removing mall pgm fuse n open door n turn key to acc. Doesnt work. The fob I have was for gp why it not work?


Important: All transmitters which are to be recognized by the remote control door lock transmitter (RCDLR) must be programmed in a single programming sequence. If the system is placed in program mode it will erase all previously programmed transmitters upon the receipt of the programming signal from the first transmitter. Up to four transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.
  1. Remove the ignition key from the ignition lock cylinder.
  2. Close all of the doors.
  3. Remove the MALL PGM fuse from the fuse block.
  4. Insert the ignition key into the ignition lock cylinder.
  5. Turn the ignition to ACC.
  6. The body control module (BCM) will perform the following in order to identify the type of BCM installed in the vehicle:
    ?€¢
    Flash the seat belt indicator 1, 2, or 3 times.


    ?€¢
    Chime 1, 2, or 3 times.

  7. Turn the ignition to OFF, and then back to ACC within 1 second.
  8. The BCM may begin to chime and flash diagnostic trouble codes (DTCs). If the BCM has stored any DTCs, refer to Diagnostic System Check - Body Control System in Body Control System.
  9. Open and then close any vehicle door.
  10. The BCM will chime in order to confirm that the programming mode has been entered.
  11. Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for approximately 14 seconds.
  12. Important: After approximately 7 seconds the BCM will chime once to confirm that synchronization has been completed. After approximately 14 seconds the BCM will chime a second time to confirm that the programming has been completed.
  13. Repeat the previous step in order to program each additional transmitter.
  14. Remove the ignition key from the ignition lock cylinder.
  15. Install the MALL PGM fuse into the fuse block.
  16. Operate the functions of each transmitter in order to verify correct system operation.

No electric power to left door Fuse and relay are good


Check the wire lume that runs from the body to the door inside a rubber bellow. the wires can break from constant moving and I'm not sure what vehicle you have, but this is a defect for a few vehicles out there the wire can be to short in some cases from cost saving manufacturing. It may be necessary to remove the door panel and remove the harness through the wire opening to be able to move the boot far enough to access the broken wire or even just to check it in some cases.
How I like to repair it, is to put a new wire through the entire pivot point and join it inside the door and body where the wire does not move constantly.

Hope this helps
