2005 Buick Rendezvous you can hear the relay clicking but the door locks will not open and close


Check for broke wires inside the boot from body to driver door , this is a common problem . If you don't find broke wire's , pull the door panel to get at driver door switch . Check for voltage an ground circuit .
Rendezvous 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


?€¢
Door lock system fuse into the BCM (BCM D 25A fuse)


Door Lock Operation
When the 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 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 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 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 seperate from the passenger doors using a keyless entry transmitter or an automatic door unlock function (if programmed). This video on testing computer controlled door locks on a Subaru , doesn't matter . test yours same way > The BCM controls your door locks .
Are all of the power door locks inoperative from both door lock switches?

Driver side door will not lock/unlock with the remote, but the other doors will.


no you needs a new lock actuator on that door its about $90 installed,
all the locks are on same circuit . sorry about the bad news :(

Driver door's handle doesn't unlock all the 4 doors.It unlocks only driver door.Before the touch handle use to unlock all the 4 doors.The same works well from front passenger door.


The vehicle can be programmed to either open all the doors, or just the driver door. Check in the main menu for changing that function from just drivers door to all. (its also outlined in your owners manual)

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.

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.

Driver side door locking with remote but will not unlock, if i unlock it with key then remote will unlock all other door, if all doors are locked remote will not unlock the car. Once i manually unlock...


it is not the actuators, try a different remote, you may have an issue with the car security system/body computer not functioning on the unlock driver door command, one press of remote is unlock driver door and 2 presses is unlock the other doors.

My 1989 Chrysler LeBaron with power door locks has the paasenger side door jammed. Any ideas on how to unjam it?


Hi
If the Problem is That you Can't Unlock the Door With Door Unlock Switch, Or The Key Outside of Door, nor can you Unlock Door with Manual Unlock Button [ Electrical Lock Doors Only ] Then More than Likley The lock / Unlock Motor that electricaly Locks and unlocks the Door has become Defective and is Jamming the ability to Unlock the Door by any method. You will have to find some way to get to the Mechinisim to move the door lock to the Unlock Position before you can open the Door. This will be very hard with the Door Closed but you may be able to remove the cover over the inside door handle and with some moveing of the link to the lock / unlock mechensim to get the door Unlocked. If not you may have to take it to your dealer or a body shop to see if they can get the Door unlocked. Try not to force unlock with a key as this will damage the Keylock Mechinism.
Then you will have to replace the Door lock / unlock Motor or simply disconnect the linkage to the door lock / unlock Motor and use a key to lock / unlock the Door untill you can replace the motor.
This is a common problem that shows up in these older cars. In my case both of the door lock motors on my 1987 Lebaron went out about the same time but the Pasenger went out first.
Usually the first indication that this problem is about to occure is you find that the Door lock becomes harder to lock and unlock with the key or with the manual door lock button.
