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 ?

I have no power to my door locks and windows what could be the problem there's no fuse or relay as far as I know


There's always a fuse or relay. Some vehicles have 2-3 boxes in various places in the engine, under dash, behind glove box or either front door gash visibly obscured by the doors. But aside from that the usual problem is that some sort of strain against the door lock actuator such as icing or someone pulling the handle when the actuator is energized results in breakage. The answer is usually replace the door lock actuator. Prices vary and frequently each of 4 doors uses a different unit. My wife broke the SUV door last year. The actuator cost $389. Found it at a junk yard for $100. Other problems are rodent wire damage, excessive connector wear, corroded connectors. Good luck.

2008 Chevy Impala LTZ: car wont lock or unlock with the power lock/unlock buttons on the remote or car door. It makes a clicking sound though when I attempt to. Is this a blown fuse? Or something else


Where do you here the clicking sound ? in the door , behind instrument panel ? I don't think a blown fuse would do this , possibly a relay ! do you know what a relay is ? This is Chevy factory service information !
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.
There are three pcb relays integrated into the instrument panel fuse box ( non replaceable ) door unlock pcb relay drivers door -door unlock pcb relay an door lock pcb relay ! The BCM controls these relays ! Do you know what a BCM is ?
Circuit/System Description
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.
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.
With out have a factory GM tech 2 scan tool ,It would be best if you took this to a Chevy dealer . The first part of diagnosing this problem is to hook up a scan tool !

Rear doors will not unlock


Door Lock System Components
The power door lock system consists of the following components:
?€¢
The driver door switch (DDS)


?€¢
The passenger door switch (PDS)


?€¢
The body control module (BCM)


?€¢
The driver information center (DIC)


?€¢
The rear door lock/unlock relay (LBEC)


?€¢
The door lock actuators in each of the doors The rear passenger doors are controlled by the BCM through the rear door lock/unlock relay which is incorporated onto the printed circuit board in the LH BEC. The BCM controls the unlock relay by providing ground to energize the coil and controls the lock relay by providing battery voltage to energize the relay coil. The energized the relay and allows voltage to be applied to either the door lock motor lock or unlock circuits. Since the other side of the door lock actuator is connected to the normally closed contacts of the opposing relay to ground, the doors lock or unlock.
Do you know what the BCM is , body control module ! If you do not know about this stuff I strongly suggest you to it to a ASE certified repair facility ! Save yourself some money an aggravation !

A few days a go my locks on my 2002 saturn started fluttering and making clicking sounds. I can only unlock my car with the key now and all the locks have to be unlocked and locked manually. Then a few...


Do you or your husban know how to trouble shoot automotive electrical systems , using a wiring diagram and a DVOM - digital volt ohm meter ? Do you know how to trouble shoot electronic control modules an circuitry ? The BCM - body control module controls the power locks , anti-theft system . The first step in diagnosing problems like this involve hooking of a scan tool that can pull BCM codes . No auto parts store can check these codes .
DOOR LOCKING/UNLOCKING
Door locking/unlocking, by remote keyless entry (RKE) or driver/all door lock switches, is controlled through the BCM.
When a driver door unlock has been requested, the BCM switches circuit 694 to battery voltage. This energizes the driver door unlock relay which supplies power to the driver door lock motor. Grounding is achieved through the closed contacts of the all-door lock relay. Grounding is also achieved through the windings of the all-door lock motors and the all-door unlock relay.
When an all-door unlock has been requested, the BCM switches circuit 194 to battery voltage. This energizes the door unlock relay which supplies power to the all-door lock motors. Grounding is achieved through the closed contacts of the door lock relay. Grounding is also achieved through the winding of the driver door lock motor and the driver door unlock relay.
When an all-door lock has been requested, the BCM switches circuit 195 to battery voltage. This energizes the door lock relay which supplies power to all-door lock motors. Grounding is achieved through the closed contacts of the door unlock relay and the BCM.
Lock/Unlock power application is limited by the BCM to 7 seconds to protect lock motors.

SECURITY SYSTEM
The passlock sensor is powered by circuit 1459. The passlock sensor is grounded by circuit 1835. Passlock sensor data is supplied to the BCM by circuit 1836.
The passlock sensor data supplied to the BCM is in the form of V-codes or voltage codes. When the proper ignition key is turned in the ignition switch, the correct V-code is supplied to the BCM. The BCM responds by sending a serial data password to the engine controller allowing the engine to run.
Under a tamper condition, a specific V-code is supplied to the BCM. The BCM will send a class II message to the PCM disabling the fuel injectors.

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

    Camry 1996 automatic power lock doen't work, but windows work.


    if you can here relays when unlocking/locking check for power at door lock actuators inside doors, if you have power on lock/unlock and good earth from connector actuators are faulty.
    if no power on test light when operating check output from central door lock module while operating, none coming out of module then it might need replacing.
    check 30Amp power fuse for main relay under bonnet (which goes to pin 8 white/blue on module)and 10Amp gauge fuse in cab(pin 1 blue/red on module),pin 15 is also power when relay is on(red/blue) with test light, and module/ actuators.
    check outputs from module pin 3 & 4
    blue/red
    blue/black
    that go to door locks
