SOURCE: Door locks don't work

Disassemble the paneling on left side ,under the steering wheel. Remove all screws and pull out the panel until you can you can reach behind it to remove the two Black Relays, on the side closest to Steering wheel. Remove the Relay covers, Clean the contacts with a 1/8 fine strip of 600 wet/dry sand paper. Only place the paper between the contacts, and pull out while holding slight pressure on the relay Armature. Turn over the sandpaper and repeat once again. Very gently press the TOP resting contact pad closer to the armature, to lessen the gap between the contact points, so the armature doesn't have to travel as far to reach the closed contact position. Repeat the above with the other2nd Relay. Replace the covers, reinstall the relays And test the Door locks prior to buttoning up the paneling. Note, a pair of long needle nosed pliers will help in removing the relays. Just Grip the relay and rock in Forward and Backward as you apply upward pressure.

SOURCE: Ford F150 Pickup 2005 power doors unlock but will not lock

I had almost the identical problem on my 2005 F150 FX4 Extended cab last weekend. The power door locks would not lock using the keypad, remotes, or door buttons. Almost all other functions worked correctly. The doors unlocked, the radio delay functioned, and the interior lights dimmed. When I used the remote the horn would beep twice indicating that a door was open even there was no message on the message center that a door was open. When I used the keypad or remote, I could hear a soft click from behind the seat. I think it was coming from the body security module or body security module - whatever Ford is calling it this year. I pulled the fuse for the Power Door Locks(BSM). As I removed it, I heard a soft click - sort of like a relay resetting. It may have come from the VSM/BSM. It may have possibly been a stuck actuator releasing. I don't think so. It wasn't that load. In any case, everything is functioning correctly now.

SOURCE: land rover discovery central locking.

No, likely to be caused by the actuators in the lock mechanism failing usually causing the door to remain locked. The boor door can also fail this way, as do the front side doors. Replacement requires the whole lock unit to be replaced at a cost of roughly £60 a lock, and a hours work. Helps if you have small hands. Requires a full strip down of the door and you will need the lock unit, trim clips (a few quid) and a trim removal tool (tenner). You can bodge with a flat head screwdriver, but the tool does help prevent damage to the clips & trim panel.

SOURCE: where is the door lock relay located on a 1999

  • Aux Relay Box #4 is in the rear driver's side removable panel with the tire jack.
  • This Relay box holds the Door Lock / Unlock relays (ice cube type). It also holds the Driver Door Unlock Relay and the ACC Lights Relay (rectangular relays).

    2005 Chevy Equinox Driver & Passenger Door Unlock Relay. How To Remove & Install. They Are Power Locks. Front Doors Must Roll Windows Down Use Hand To Open Thanks. Ms. J. C.


    Door Lock and Unlock Operation
    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 circuit(s) to battery positive voltage. This will energize the appropriate lock or unlock relay(s). 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 lock. Driver door unlock, passenger door unlock and all door lock. This is done to isolate the driver door lock actuator so it can be unlocked by itself using the keyless entry transmitter.
    Your door locks are controlled by the BCM - body control module (a computer ) . An a scan tool is a must to diagnose system operation . Your best bet would be to take your vehicle to a qualified repair shop . The only way you could try to fix this is by changing parts ! Suppose you find an replace a door lock/ unlock relay an that doesn't fix it ? There could be DTC'S stored in the BCM . Do you know what a DTC is ?

    Door lock dont always work


    What door lock doesn't always work ? One or all of them . This is a complex set up for these door locks ! The switch is an input to the BCM - body control module . There is logic involved in the microprocessor , there are relays built in to the BCM ! Could have a DTC - diagnostic trouble code stored in the BCM ! Could be a bad connection at the BCM or master window switch ! A bad ground !
    The power door lock system consists of the following components:
    ?€¢
    Body control module (BCM)


    ?€¢
    DOOR LKS fuse


    ?€¢
    Driver door lock actuator


    ?€¢
    Driver door lock switch


    ?€¢
    GMLAN serial data link


    ?€¢
    Keyless entry transmitter


    ?€¢
    Passenger door lock actuator


    ?€¢
    Passenger door lock switch


    ?€¢
    Remote control door lock receiver (RCDLR)


    The DR LCK fuse supplies battery voltage to the body control module (BCM) for the power door lock system. The BCM supplies and monitors a reference voltage to the driver and passenger door lock switches through the door lock switch lock/unlock signal circuit. Each door lock switch receives ground at G300 which is also the ground for the door lock and unlock relays located in the BCM. When a door lock switch is placed in the lock position, the reference voltage is switched to ground and the BCM senses 0.0 volts on the door lock/unlock signal circuit. When a door lock switch is placed in the unlock position, the reference voltage is switched to ground through a 1.5k ohm resistor that is internal to each of the door lock switches and the BCM senses approximately 2.9 volts on the door lock/unlock signal circuit. The BCM interprets what position the activated door lock switch was placed in based on the voltage drop.
    The BCM, upon receipt of a lock or unlock switch signal, will switch the appropriate door lock/unlock relay coil control circuit to ground causing the appropriate door lock/unlock relay to energize. With the relay energized, voltage is applied to the door lock actuator control circuit causing the door to either lock, or unlock depending on what command was received from the power door lock switch or remote control door lock receiver (RCDLR). When a power door lock/unlock relay is not energized, the switch contacts are normally grounded through the BCM which provides ground to the appropriate door lock actuator for the lock/unlock function being performed. The power door lock/unlock functions are performed by reversing the flow of voltage through the door lock actuator control circuits. The BCM has three internal drivers for the power door lock system. Driver door unlock, passenger door unlock and all door lock. This is done to isolate the driver door lock actuator so it can be unlocked separately from the passenger door. For additional information concerning keyless entry, refer to Keyless Entry System Description and Operation.
    This is one you may want to take to dealer or some other ASE certified repair shop ! To do this right you need a Tech 2 scan tool !
    Ignition ON, observe the scan tool Door Lock Switch parameter while using the driver and passenger door lock switches. The parameter should change from Idle to Lock and Unlock.
    ?‡'
    If the value does not change, refer to Door Lock Switch Malfunction.

    Command the doors to LOCK and UNLOCK with the scan tool, the door lock actuators should LOCK and UNLOCK when changing between the commanded states.
    ?‡'
    If one or more doors do not LOCK or UNLOCK, refer to Door Lock Malfunction.

    DOOR LOCK RELAY LOCATION


    Try swapping the door switches to see if that corrects the problem. Each door is not controlled by a relay. If one door has power, they all have power. Look at the body control module too. All door lock functions go thru it.

    Sunroof will not work


    Power is supplied to the Power windows and sunroof through the power window circuit breaker. That circuit breaker is supplied power through the RAP (retained accessory power) Relay, the RAP relay also supplies power to the radio. The RAP relay is also fuse protected by the RAP fuse in the under hood fuse block. The RAP relay is energized by the BCM body control module.

    The RAP relay is responsible for the radio and windows working after the igntion is turned off.

    The first place to check would be the RAP fuse in the under hood fuse block and then the RAP relay in the Body fuse block.

    A list of the BODY relay block located on the left side of the dash to the right of the interior fuse block is below:

    (1) Park Lamp Relay (2) Courtesy Lamp Relay (3) Retained Accessory Power (RAP) Relay (4) Power Seats Circuit Breaker (5) Power Windows Circuit Breaker (6) Inadvertent Power Relay (7) Door Lock Relay (8) Headlamp Ground Relay (9) Driver Door Unlock Relay (10) Door Unlock Relay(1) Park Lamp Relay
    (2) Courtesy Lamp Relay
