Not to insult your intelligence or anything, but I had the same problem, and fixed it by replacing fuse #13. It was caused by a short in my cigarrette lighter. Good Luck!

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).

2003 crown vic keyfob only works with ignition in run position .keyless entry and door locks work fine.even tried new keyfob.no change


The keyless entry system consists of the following components:
  • driver door module (DDM)
  • keyless entry transmitter
  • keyless entry keypad
The driver door module (DDM) receives inputs from the digital transmission range (TR) sensor, ignition switch, brake switch, window/door lock switches, lighting control module (LCM), keyless entry keypad switch and remote transmitter. The DDM outputs consists of keyless entry keypad switch illumination, power door lock actuators, luggage compartment release solenoid, horn relay, and lighting control module (LCM).
  • Battery junction box (BJB) fuses:
    • circuit breaker 7 (20A)
  • Central junction box (CJB)
    • 4 (10A)
    • 6 (15A)
    • 8 (25A)
    • 13 (5A)
  • Keyless entry keypad switch
  • Power door lock actuator
  • Luggage compartment release switch
  • Luggage compartment release solenoid
  • Connectors or connections
  • Wiring harness
  • If fuse's good have checked for DTC'S - diagnostic trouble codes .
  • B1526 Keyless Entry Circuit Short to Ground DDM Go To Pinpoint Test E . B1553 Decklid Release Circuit Short to Battery DDM Go To Pinpoint Test B . B1751 Park/Neutral Switch Circuit Short to Battery DDM Go To Pinpoint Test K . B2425 Remote Keyless Entry Out of Synchronization DDM Go To Pinpoint Test L Need a professional grade scan tool to check fro these codes . Not a code reader for OBD2 codes .
  • The doors do not lock/unlock using the remote transmitter
  • Remote transmitter not programmed.
  • Remote transmitter.
  • DDM.
  • Go To Pinpoint Test F .

Did you program the new key fob ?

Remote Transmitter Programming NOTE: All remote transmitters are programmable and must be set at the same time.
  1. Turn the key from OFF to RUN four times within three seconds, ending in RUN. The locks will then lock and unlock, confirming program mode has been entered.
  1. Press any button on each remote transmitter to be programmed. The doors will lock and unlock to confirm that each remote transmitter has been programmed.
  1. If additonal remote transmitters are to be programmed, repeat Step 3 within 7.5 seconds or steps 2 and 3 if more than 7.5 seconds have elapsed.
  1. To exit program mode, turn the ignition to START or wait 7.5 seconds.
  1. NOTE: Failure to wait at least 20 seconds will cause programming failures. Wait at least 20 seconds after turning the key to OFF or after the last remote transmitter has been programmed to activate a remote transmitter for testing or verification

My hatch won't release from the remote or the door switch. No solenoid sound at the hatch. How do I get it to open if it's not a bad fuse?


There are actually three relays , an there are controlled by the BCM - body control module !
When a door lock switch is activated in the lock or unlock position the BCM will receive a voltage signal on either the door lock switch lock or unlock signal circuits.
The BCM, upon receipt of a lock switch lock or unlock signal, will switch the appropriate lock relay control circuits to battery positive voltage. This will energize the appropriate lock or unlock relays. The relay will supply voltage to the door lock actuator lock or unlock control circuits to one side of the lock actuator. Since the opposing side of the lock actuators are connected to ground through the other lock actuator control circuit and the normally closed contacts of the lock or unlock relay, the doors and liftgate will then lock or unlock appropriately.
Three relays are used to operate the locks. DRV DR UNLCK relay, PASS DR UNLOCK and DR LCK relay. This is done to isolate the driver door lock actuator so it can be unlocked by itself using the keyless entry transmitter.
Rear Hatch/Gate Description and Operation
The liftgate 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 liftgate actuator when a release input is received through the key fob, or the instrument panel switch.
Door/Lift gate Latch Assembly
  1. Install a 20-A fused jumper wire between the control terminal 3 and 12 volts. Install a jumper wire between the ground terminal 2 and ground.
  2. Verify the actuator turns on & off.
?‡'
If the function does not perform as specified, replace the applicable door latch.

07grandprix my door locks are all actin up sometimes they work & sometimes they dont I can set the alarm even tho they wont lock & the alarm goes off if u open the door but won't lock with the key/pad


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).


?€¢
A last door closed locking (LDCL) 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).
Faulty electrical connections or wiring may be the cause of intermittent conditions. Refer to Testing for Intermittent Conditions and Poor Connections.
A factory scan tool would help for checking inputs from the door switches to the BCM ! You could do it with out scan tool , a lot more work involved ! Need a wiring diagram an a component location chart an wiring harness routing diagram !
Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items:
?€¢
Wiring broken inside the insulation


?€¢
Poor connection between the male and female terminal at a connector


?€¢
Poor terminal to wire connection--Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc.


?€¢
Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits.


?€¢
Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle.


?€¢
Wiring that comes in contact with hot or exhaust components


?€¢
Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern.


?€¢
Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions.


?€¢
Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation.

How do i reprogram electronic door locks


Programming Electronic Door Lock Control System NOTE: The electronic door lock control processor (14B001) erases all previous keyless entry remote transmitter (15K601) from memory when the keyless entry remote transmitters are programmed or reprogrammed. The electronic door lock control processor can store up to four keyless entry remote transmitters in memory.


  • To program (or reprogram) keyless entry remote transmitter into the electronic door lock control processor, perform the following steps:
  1. Turn ignition switch to the RUN position and momentarily short the two terminals of the program connector taped to the wire assembly and located behind the glove compartment. All doors should lock and then unlock. Remove shorting pin.
  1. Press any button on keyless entry remote transmitter. All doors should lock and then unlock to verify the keyless entry remote transmitter has been programmed. If door locks do not respond, press button again (up to three times maximum with the same keyless entry remote transmitter).
  1. Repeat the above step to program additional keyless entry remote transmitters into the electronic door lock control processor (up to four keyless entry remote transmitters maximum).
  1. Turn ignition switch OFF. All doors should lock and then unlock.
  1. Check operation.

I have a 98 GMC JIMMY. Remotes and Dome Lights stopped working. Car would start then immediately die. Took it to the dealer and they stated it was the Body Control Modual (BMC). Picked up the vehicle...


Keyless Entry System Circuit Description
The Power Door Locks/Remote Keyless Entry control system provides several functions. The driver operates the vehicle door locks and rear window release from outside the vehicle using a hand-held radio transmitter. The transmitter sends coded signals to the remote control door lock receiver. The remote control door lock receiver detects and decodes the signal from the transmitter. The remote control door lock receiver issues signals to the body control module (BCM) through a serial data link. The BCM actuates relays to lock and unlock the doors and liftgate. The BCM can also release the liftglass. The power door lock switches provide manual control of the door locks.


Transmitter Programming
Important: Different keyless entry systems are used on General Motors vehicles. The parts are not interchangeable even though the parts may appear to be similar. Observe the back of the transmitter in order to properly identify the system. On 1998 S/T pickups and utilities, use a transmitter identified with GM/UTA preceding the part number.
With the driver door closed, hold down the power unlock button on the door panel.
Turn the ignition switch to the ON position.
Turn the ignition switch to the OFF position.
Turn the ignition switch to the ON position.
Turn the ignition switch to the OFF position.
Release the power unlock button on the door panel.
The remote control door lock receiver will respond in the following manner in order to indicate that the receiver is in the programming mode:
6.1. Locking the doors
6.2. Unlocking the doors
Important: All extra transmitters must be programmed at this time. When a new transmitter is programmed, it will deactivate the old transmitters.
Hold down the lock and unlock buttons on the transmitter until the remote control door lock receiver will respond in the following manner:
7.1. Locking the doors.
7.2. Unlocking the doors.
Repeat step 7 for each additional transmitter.
Turn the ignition switch to the ON position in order to exit the transmitter programming mode.
