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?

Passanger side doors wont lock

From where , any switch ? driver door switch or either passenger door switch . This is a very complex system controlled by modules (microprocessors)
?€¢
The driver door switch assembly (DDSA)


?€¢
The driver door module (DDM)


?€¢
The passenger door module (PDM)


?€¢
The rear door module (RDM)


?€¢
The LH front power door lock switch


?€¢
The RH front power door lock switch


?€¢
The LH front door lock actuator


?€¢
The RH front door lock actuator


?€¢
The LH rear door lock actuator


?€¢
The RH rear door lock actuator


?€¢
The remote control door lock receiver (RCDLR)


?€¢
The power door serial data circuit


?€¢
The class 2 serial data circuit


?€¢
The DRVMDL Fuse - 10 amp


?€¢
The PDM Fuse - 10 amp


?€¢
The RRINMDL Fuse - 10 a
Class 2 and Power Door Serial Data Links
The class 2 and power door data circuits are both serial data links. The serial data circuits replace cables in the vehicle by multiplexing (time-sharing) data to and from each device over a single wire referenced to ground. If the power door serial data is lost, both the rear door module (RDM) and the passenger door module (PDM) enters the sleep mode. With the RDM and the PDM in sleep mode, no power door operations are possible.
Your best bet is to take it to the dealer or an ASE certified repair shop .

Why does my 2004 Chevy Silverado lock and unlock while in drive? When turned off and no keys in ignition the drivers door will unlock on its own a short time later.

Gremlins ! HA HA HA sorry ! First off a little bit on how they work an what all is involved in making them work ! There are a few control modules in the mix , switches ,relays etc...
Door Lock System Components
The power door lock system consists of the following components:
?€¢
The driver door module (DDM)

?€¢
The passenger door module (PDM)

?€¢
The body control module (BCM)

?€¢
The driver information center (DIC)

?€¢
The rear door lock switch

?€¢
The door lock relay

?€¢
The door unlock relay

?€¢
The liftgate lock relay--utility vehicles with liftgate only

?€¢
The reversible door lock actuators in each of the doors and liftgate

?€¢
LOCKS 20A fuse (rear lock/unlock relay supply voltage)

?€¢
ECC 10A fuse (liftgate lock relay supply voltage)

Door Lock System Controls
The power door lock system can be controlled by any of the following:
?€¢
A power door lock or unlock switch activation

?€¢
A keyless entry transmission

?€¢
An automatic door lock function

?€¢
A delay lock function

?€¢
Door lock cylinder switch activation

?€¢
Lockout Prevention

?€¢
An airbag deployment

The front power door lock switches are integral components of the driver door module (DDM) and passenger door module (PDM). The switches are two position normally open rocker switches. When placed in either the lock or unlock positions, the switches provide a direct input to the DDM or PDM. The DDM or PDM monitors these inputs and sends a Class 2 message indicating a change in the switch's respective position. Modules which activate the power door lock motors receive the Class 2 message and activate the motor in the appropriate direction to lock or unlock the vehicle's doors and liftgate. The rear door lock switch provides a lock and unlock signal to the body control module (BCM). The BCM upon receipt of a lock or unlock signal will control the rear door lock relays and also send a Class 2 message to the DDM and PDM to perform the appropriate function.
The modules which activate the power lock motors are:
?€¢
The DDM (driver door lock actuator).

?€¢
The PDM (passenger front door lock actuator).

?€¢
The BCM (both rear door lock actuators and cargo door/liftgate).
The DDM and PDM are directly connected to the respective door lock actuator through the door lock motor lock and unlock circuits. Once a door lock or unlock request has been received, the module will supply battery voltage to one side of the actuator and ground the other causing the doors to lock or unlock.
The rear passenger and cargo doors differ slightly in that they use lock and unlock relays. The relays supply and coil sides receive a constant voltage through the battery voltage supply circuit. The normally closed contacts are connected to ground and the control side is connected to the BCM. Once a door lock or unlock request has been received by the BCM, the BCM will ground the control side of the appropriate relay. This energizes 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.
The first place to start is have a factory or equivalent scan tool hooked up , one that can read BCM DTC'S - diagnostic trouble codes ! This could lead to a fix faster ! Watch these three videos !

I have a 08 chevy avalanche the driver side front and rear door locks won't work when I use my keyless entry button or on the inside driver panel. Could it be a fuse? Passenger side works fine I try...

Do the power windows work ? DDM - driver door module fuse 15 amp - location is the instrument panel fuse box , plus LT DR circuit breaker 25 amp. Circuit breakers rarely go bad . The power locks are controlled by electronic's .The passenger side has another power supply ,that's why they still work .
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 reversible door lock actuators in each of the doors and liftgate

The front power door lock switches are integral components of the driver door module (DDS) and passenger door module (PDS). The switches are 2 position normally open rocker switches. When placed in either the lock or unlock positions, the switches provide a direct input to the DDS or PDS. The DDS or PDS monitors these inputs and sends a LAN message indicating a change in the switch's respective position. Modules which activate the power door lock motors receive the LAN message and activate the motor in the appropriate direction to lock or unlock the vehicle's doors and liftgate. The rear door lock switch provides a lock and unlock signal to the body control module (BCM). The BCM upon receipt of a lock or unlock signal will control the rear door lock/unlock relay and also send a LAN message to the DDS and PDS to perform the appropriate function.
The modules which activate the power lock motors are:
• The DDS (driver door lock actuator)
• The PDS (passenger front door lock actuator)
• The BCM (both rear door lock actuators and cargo door/liftgate)
The DDS and PDS are directly connected to the respective door lock actuator through the door lock motor lock and unlock circuits. Once a door lock or unlock request has been received, the module will supply battery voltage to one side of the actuator and ground the other causing the doors to lock or unlock.
The rear passenger and endgate 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.

It's possible you have broken wire or wires inside the flex boot from the body of the vehicle to the driver's door . This happens a lot .

Drivers side rear door lock inoperative

You need to replace the electric solenoid/actuator for the door lock. The door panel pulls off very easily.
