I have a 2004 Yukon Denali. The driver side automatic door lock works intermittently.

Usually damaged wires in the wiring harness where is goes from the door to the door frame. The drivers side always fails well before the passenger side do to all the use it gets.

Vauxhall Meriva. Automatic locking system problems.

Question edited for clarity and make some sentences.

Likely broken wires somewhere or a failing module. You need an auto electrician or auto locksmith with a pro grade scan tool computer to diagnose.

Why don't the rear door locks work anymore?

first is fuses are they good.?
the locks on cars are solenoids.
im guessing all ways to open it fail,
keys, key fobs, and internal controls panels?
no childern locks set (some are hidden on cars)
no drivers, panel , master lock, he pushes it and all locks freeze?
this is a general statement.
so you use a thing like a volt meter. $10 at walfart.
we check for 12vdc across the 2 solenoids.
12vdc when active is good.
0v is bad,
if you get 12v then the solenoid is bad or jammed.
if you get 0v, the controls are bad.
its that simple. and electro magnetic solenoid, is easy to test.
with any voltmeter made.
if the controls are bad we use the same method to check them.
12vdc to the switch it must be.
then you push the rear switch and 12vdc leaves this switch.
if not the switch is bad.(input good)

Changed bcm because auto door locks and driver window did not work, when i changed it everything work like it should but had to relearn key , when the key was relearned the locks and window stopped working...

Taking your vehicle to a qualified repair shop instead of mess with thing's you have no clue about ,is what you should have done . Replacing BCM'S - needs to be programmed .
If the body control module (BCM) is replaced, the following procedures must be performed in the following order:
BCM reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems.
Theft learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent. A new BCM will learn the Passlockâ„¢ information automatically but the powertrain control module (PCM) must still learn the theft information from the BCM.

Plus the bcm has nothing to do with the power window's DDM -the driver door module controls the window .
Programmable Automatic Door Locks
The automatic door lock feature can be programmed to control the door lock system. The automatic door lock feature is factory programmed to have all doors lock and unlock. For detailed instructions on programming the automatic door locks, refer to Vehicle Personalization in Personalization.
When the automatic door lock feature is programmed to control the door lock system, the driver door module (DDM), passenger door module (PDM) and body control module (BCM) will lock the vehicle doors if the following inputs are true:
• Ignition 1 input is active.
• All door jamb switch inputs are inactive.
• Cargo door or liftgate/liftglass ajar inputs are inactive.
• Transmission is shifted out of park.
This automatic door lock function will only occur once per ignition cycle unless, a door jamb switch input changes state to active and back to inactive. Then the DDM, PDM and BCM will lock all doors again.
Once the automatic door lock feature has locked the doors, the BCM will then unlock all the doors when the transmission is shifted into park.
Before replace these componets hooking up a factory scan tool an checking data input's an DTC'S - diagnostic trouble codes .

My remote lock stoped working. I can unlock doors from inside but cant lock them. It's a 1998 Cherokee Sport

You do not specify, whether you ability to lock the doors is inside the vehicle, or with a remote. Are you the only one in the vehicle most times it is used? Is there another "rocker" switch, on another door to see if it will lock a door. In most cases (not all) it is a simple matter of replacing the switch. Automatic lock, & automatic windows, operate on the technical term of a 'momentary' contact switch. As long as it is being pressed, it is sending current, into the lock or window to make it operate the device in the direction you want. If the other side of the switch fails.......nothing. I think this is where you should start. Napa, is a good source for "look alike" replacement switches.

Key fob locks car then unlocks it

when inside the vehicle and you driveaway the door lock and then probably with your issue unlock automatically.
One of the front door latches/actuator assembly has failed.
You need to look at both the front locks when locking the vehicle (where the handle is) look and see which ones do not lock.
It will be either the drivers front or the passenger front.
Once determined, that latch assy will need replacing

What and where do I disconnect.

Ah Yes..good reason.

Go to your fuse panel (under your dash). Remove the fuse marked "door". It may be named something else, perhaps "locks".

Once you find and remove the fuse, give it a try at speed. Hopefully the fuse only supplies door lock power and not your windows. More than likely this will render your door locks completely manual.

However, there was a recall on this vehicle for this problem.

NHTSA Campaign ID Number: 92V135000
Component: Structure: Door Assembly: Latches And Locks
Manufacturer: Toyota Motor Co., Ltd.
Year: 1989
Make: Toyota
Year of Recall: 1992
Type of Report: Vehicle
Potential Number of Units Affected: 554,910
Defect Summary:
The electronic control unit (ECU) for the power door lock system can fail, causing the contacts to "weld", and resulting in door lock solenoid damage, with failure of the door to lock or unlock, even under manual operation.
Consequence Summary:
If the door fails to open after ECU failure, vehicle occupants would have increased difficulty exiting the vehicle in an emergency.
Corrective Summary:
Install an additional sub-circuit relay control to prevent malfunction of original relays in the ECU.

So the thing to do is contact your local Toyota dealer and have the recall performed.

I hope this helps!

2005 Chevrolet Silverado Automatic door locks

I assume you mean that the central locking system will not lock the doors but you can do so manually.

Get inside the vehicle and close all doors.

On each rear door, lock and unlock the mechanism manually a couple of times. In other words do not use the key pad.

Then leave both rear doors in the locked position (manual locking) and operate the lock button on you key pad to operate the central locking system. Wait a few seconds then hit unlock on your key pad and a few seconds later hit lock on your key pad.

If the system fails to lock your rear doors you will need to get the vehicle to an auto electrician to check out the issue and rectify it for you. There are a number of possible causes which cannot be identified without physically checking the system. So you will need to have this rectified by a professional.
