Auto door locks not working

It definitely sounds like you have a bad shifter cable. Not a very expensive part, but can be a pain to get changed.

Have the vehicle checked for DTC'S diagnostic trouble codes stored in the BCM - body control module . Everything is electroniclly controlled .
Automatic Transmission Shift Lock Control Description and Operation
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
• The automatic transmission shift lock solenoid (serviced as the automatic transmission shift lock actuator), as well as the body control module (BCM) and the engine control module (ECM). The shift lock solenoid is located within the floor shift control assembly with vehicles equipped with floor shift.
• The BCM controls the voltage to the shift lock control solenoid through the shift lock control solenoid controlled voltage circuit. The following conditions must be met before the BCM will remove voltage from the shift lock solenoid:
- The ignition is in the ON position.
- The engine control module (ECM) sends an input via GMLAN serial data to the BCM indicating the transmission is in the PARK position.
- The BCM determines the brake pedal is applied according the brake pedal position.
Since the shift lock control solenoid is permanently grounded, the BCM supplies voltage to the automatic transmission shift lock control solenoid, mechanically locking the shift lever in the PARK position as the solenoid energizes. When the brake pedal is applied, the BCM turns the control voltage output of the shift lock control solenoid OFF, de-energizing the shift lock control solenoid. The de-energized solenoid releases the mechanical lock allowing the driver to move the shift lever out of the PARK position. When the transmission is out of the PARK position, the shift lock control solenoid remains de-energized.
During remote start operation, the BCM will energize the shift lock control circuit, locking the shift lever in the PARK position.

The 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, the reference voltage is taken directly to ground and the BCM senses 0.0 volts on the signal circuit. If a door lock switch is placed in the unlock position, the reference voltage is taken to ground through a 15k ohm resister that is internal to the door lock switches and senses approximately 2.9 volts on the signal circuit. This is how the BCM determines what portion of the door lock switch was activated.

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 Passlock™ 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 .

If you start it in neutral, the auto locks don't auto lock. As an mechanic, I start in neutral out of habit because it technically reduces wear by avoiding going through reverse.shift out of park while in acc to nuetral and start

does this help? look in owners manual for how to turn "on or off" the auto lock feature.


Automatic Door Lock/Unlock
The automatic door unlock function is a vehicle personalization feature with the following 3?programmable modes of operation:
1. All: All of the doors will automatically unlock. 2. Driver: The driver's door will automatically unlock. 3. None: The doors will need to be unlocked by a door switch command or by pressing the the lock button on the RKE transmitter. The All or Driver modes may also be programmed as to when the automatic door unlocking will occur.
1. Key Off: The door(s) will unlock when the key is turned off. 2. Shift to Park: The door(s) will unlock when the vehicle is shifted into P (Park). The delay lock function may be enabled or disabled. When the function has been disabled, the doors will only lock by a door switch command or by pressing the the lock button on the RKE transmitter. When enabled, the doors will not lock until five seconds after the last door is closed.

If they lock after you start to drive forward...and automatically unlock when you stop and place gear shift in park...that is a safety design...Many car builders use this, with certain variables as to when to auto lock, and auto unlock...if the locks are working on there own after you have started driving...that is another problem. Your owners manual should address how the locks in your Mazda 6 are designed to work. Hope this helps.

Typically on autolock cars, when you pull the door handle to open it opens without having to unlock it. The auto lock is a safety feature. Some cars will auto-unlock when you stop, but most wont, you have to hit the unlock button. If yours doesn't auto unlock, the only way to change it would to be to install a switch somewhere on the shift mechanism, it would take a while to do.

You may have a bad master door swith assembly or more fuses out.

The 2006 Vibe no longer has that feature. It was discontinued after 2005. I have the 2005 so I know how to change it. If your 2006 is able to change then here are the directions from my 2005.
Programmable Automatic
Door Locks
If you have an automatic transaxle, your vehicle is equipped with an auto door lock/unlock feature which enables you to program your power door locks.
Your vehicle left the factory programmed to Mode 4.
The following is a list of the available programming options:
Mode 1: All doors and liftgate lock when the shift lever is moved out of PARK (P) with the ignition on and all doors and liftgate closed. There is no automatic door unlocking.
Mode 2: No automatic door locking or unlocking.
Mode 3: All doors and liftgate lock when the shift lever is moved out of PARK (P) with the ignition on and all doors and liftgate closed. All doors and liftgate unlock when the shift lever is moved to PARK (P) with the ignition on.
Mode 4: All doors and liftgate lock when the shift lever is moved out of PARK (P) with the ignition on and all doors and liftgate closed. All doors and liftgate unlock when the ignition switch is turned from ON to ACC or to LOCK.
To change the mode you are in, do the following:
1. Set the interior lamp control dial to the door position.
See Interior Lamps Control on page 3-16.
2. Move the shift lever into PARK (P) and close all doors and liftgate.
3. Turn the ignition to ON.
4. Within five seconds after the ignition is turned to ON, press and hold the power door lock switch in
the lock position for about five seconds.
5. The interior lamp will flash to indicate that the mode has been changed. For example, if the lamp flashes once, the function has been changed to Mode 1.
If the battery is disconnected or run down, the mode is changed to the initial mode which is Mode 4.

the noise is the relay clicking for the shift lock release....the auto door lock setting needs to be turned on...it should tell you how in the owners manual...
