Power Lock Unlock Rocker Switch

Both the driver and passenger side door lock/unlock switches do not operate locking or unlocking. Keyless entry and the switches on the key fob work. All doors lock and unlock normally, just not with the armrest rocker switches. Since both switches don't operate, I tried looking for a fuse, but all logical choices on the fuse list are ok. Where can I look for the problem. Have also tried the programming method of turning off the auto lock. This will work with keyless entry pad, but not the armrest rocker switches.

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).

Passenger door locks don't unlock.


You need to understand how they work , do you know about automotive electronic controls ? Your switches are just inputs to the BCM - body control module !
Door Locks Power and Ground
For door lock operation, the IP Fuse Block supplies battery positive voltage, through the 15 amp DR LK/TRUNK fuse, to the BCM. The BCM uses this circuit exclusively to apply power to the door lock actuators. The BCM is also supplied a ground circuit, which it uses exclusively to ground the door lock actuators. When a door lock is pulsed, the BCM internally connects these two circuits to the appropriate lock and unlock control circuits to actuate the locking or unlocking functions.
When diagnosing door lock malfunctions, these circuits must not be confused with the other battery voltage and ground circuits of the BCM. The appropriate wiring schematic must be used to locate the correct circuits. Failure to identify the correct battery voltage and ground circuits of the BCM during diagnosis of door lock concerns may result in misdiagnosis and unneccessary parts replacement.
Passenger Door Unlock Operation
When the 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 actuators transition to the Unlock position.
The door lock actuator unlock control circuits are dedicated control circuits used only for the passenger door lock actuators. This is done so that the driver door may be unlocked individually before unlocking the passenger doors using a keyless entry transmitter or an automatic door unlock function, if programmed. When the keyless entry transmitter is used to unlock the passenger doors, the BCM requires a repeated unlock command before it performs the unlock function. However, when the unlock input is from a door lock switch, a single unlock command is all that is required to unlock all doors.

My keyless entry for my 2008 Volvo s 40 won't work. I've tried replacing the battery but it still doesn't work. Anything I may can do before spending money on a new key.?


How are you trying to open the door , button on key fob ? With this system you can pull up on the drivers handle an it activates Antennas in the external side door handles (C30/C70 front doors, S40/V50 rear doors)
  • Antennas in the passenger compartment and cargo compartment
  • An antenna in the rear bumper
  • Quick lock motors in the lock units in the side doors
  • The remote keyless entry (RKE) receiver receives a signal from the key
  • The switch in the clutch pedal (manual transmissions) or a signal from the brake pedal switch via the central electronic module (CEM) (automatic transmissions)
  • Key-in switch.
  • Switch in door handle and lock button on handle .
    If a door handle is pulled outward, a switch closes that wakes up the system and activates the antennas in the handles on the side where the handle has been pulled out. If a valid key is within a radius of approx. 1.5 metres from the handle, the relevant door will open and the vehicle will unlock one or several doors. Which doors are unlocked depends on the settings for the system. The vehicle can also be unlocked if the handle is affected on the tailgate.

    The locks on your vehicle are electronically controlled by the BCM - body control module . The driver an passenger door switche's are input's to the BCM . Do you know anything about automotive electronic's ? anti theft alarm remote, could this be part of the problem , No it's just a key less entry remote , nothing to do with the anti-theft .
    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
    • Door lock actuators in each of the doors
    • IBCM (PWR) 15-amp fuse

    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 actuation
    • An automatic door unlock actuation
    • A last door closed locking (LDCL) actuation

    Driver and Passenger Door Unlock Operation w/o Keyless Entry
    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 driver passenger door lock actuators transition to the Unlock position.

    Rocker switches,nor remote will lock or unlock doors fuse good


    So , the power door locks won't lock or unlock with switches inside the vehicle or with the keyless entry remote fob.??? Is this correct ????
    Do you know what a BCM - body control module is ? Do you know what diagnostic trouble codes are ? If not your best bet would be to take your vehicle to a GM dealer or someother qualified repair shop.
    DTC B3142 or B3143
    The body control module (BCM) provides an output to the driver switch assembly through the door unlock control circuit for controlling automatic door unlock, anti-lockout, and keyless entry unlock functions.
    DTC B3152 or B3153
    It could be the driver door master switch , could have broken wires inside the rubber boot from the body to the door . Do the power windows work ?
    The keyless entry system has the following main components:
    • The transmitters
    • The body control module (BCM)
    When you press a button on a transmitter, the transmitter sends a signal to the BCM. The BCM interprets the signal and activates the requested function.

    How did you do this ,,checked and made sure locks and remote programmed,they were,but still do not work ?????

    Need a scan tool to program
    Important: All key fobs must be programmed each time any one fob is programmed. The scan tool must stay connected until all of the transmitters are programmed.
    Install a scan tool and navigate to the BCM Module Setup menu.
    Select Program Key Fobs.
    Follow the scan tool on-screen directions.
    When the programming operations have completed, operate the transmitter functions to verify correct system operation.

    Car will not unlock.


    To get inside the car .... Use the key in the lock cylinder, unlock the drivers door to get inside. You shouldn't have to reprogram the fob unless it or the keyless module was changed. There may be a blown fuse that supplies the keyless control module (check the owners manual for location). or wires that lead into the Drivers door may be damaged ... The keyless module is located inside the drivers door at the bottom behind the door panel ... do the unlock/lock and trunk release switches on the inside of the drivers door operate the locks and or trunk release? If so it is not the fuse ... and not the wires to it ... And it could be your BCM body control module, located in the dash board to right of your gas petal. Because the number entry keypad (code for that is on the inside of the right passenger trunk bracket arm) also doesn't work I assume it's not the key fobs themselves. Your 98 manual is correct for your car.
