Its the Door jam switch one of them is most likely Damaged~
you can change it your self if you feel up for it or tell the mechanic to do it~

oh door jam switches are those button type things that press down when the door is closed kinda like the thing in your fridge that turns off and on the light so just look at all of them and find the one that is broken and change it out just go to the dealership for the part (if you want to save some money)

or you can yell at the shop for not finding it and make them feel stupid that you know what the problem is and your not even a mechanic so they do it for free~

2005 Chevy Impala. The door locks keep locking during drive.


It's probably a bad input to the BCM - body control module ! Have it checked for DTC'S - diagnostic trouble codes .
The automatic door lock function can only be enabled by the body control module (BCM) if the driver door open switch and door ajar switches are in the Closed state. For information on programming the automatic door locks, refer to Vehicle Personalization in Personalization.
DTC B3064 or B3069
DTC B3127
DTC B3128, B3133, or B3138
DTC B3132
DTC B3137
DTC B3272
Your best bet , take it to the chevy dealer . Unless you own a GM factory Tech 2 scan tool an have access to factory sevice repair info.
.
The outputs to the door lock actuators are controlled by the body control module (BCM). When the BCM receives a lock input from a door lock switch, or a keyless entry transmitter, it applies battery positive voltage to the door lock actuator lock control circuit, a ground to the door lock actuator unlock control, and the driver door lock actuator unlock control circuits. When the BCM receives an unlock input from a door lock switch, it applies battery positive voltage to the door lock actuator unlock control, the driver door lock actuator unlock control circuits, and a ground to the door lock actuator lock control circuit . When the BCM receives an single Unlock input from a keyless entry transmitter, it applies battery positive voltage to the driver door lock actuator unlock control circuit and a ground to the door lock actuator lock control circuit to unlock the driver door. A second Unlock input from the transmitter applies battery positive voltage to the door lock actuator unlock control circuit, and a ground to the door lock actuator lock control circuit to unlock the passenger doors.

This diagnostic procedure supports the following DTCs:
• DTC B3128 Left Front/Driver Door Unlock Circuit High
• DTC B3133 All Door Unlock Circuit High
• DTC B3138 All Door Lock Circuit High

How to get into programming mode to program a remote?


Few Toyota models came equipped with remote door locks before 2008 - surprisingly!

Your car may not have the radio receiver to work with door locks. In that case, you need the radio and some wireing to pair with your remotes.

Why do the doors on my 2004 nissan quest sl keep unlocking by themselves even when the van is off?


It may be that water/moisture has gotten in behind the door panels...do you notice that it worsens in damp(er) weather? The car unlocks by itself if you leave the key in the ignition and you try and lock the doors.

Or somebody has the same coded fob (unlikely).

You might want to reprogram the remotes if you determine that the area behind the door panels is dry and there are no corroded wires, etc.

Good Luck.

2004 Nissan Quest Remote Programming Note: You must have all remotes on hand when performing this procedure. Any remotes not used during this procedure will become inactive.
1. Close and lock all doors with the driver's side power lock switch located on drivers door panel.
2. Insert key into ignition (DON'T TURN) and remove it from the ignition key cylinder at least 6 times within 10 seconds (this will need to be done at approximately one second intervals). You may need to insert and remove the key up to 10 or 12 times until your hazard lamps flash. PLEASE NOTE: Withdraw key completely from ignition cylinder each time. If this procedure is performed too fast or too slow the system will not enter programming mode.
3. Insert key into ignition and turn to the ACC position.
4. Within 5 seconds, push the LOCK button on the keyless remote. Your hazard lamps will flash. PLEASE NOTE: Do not press the button on the remote more than one time or the programming will not be successful.
5. If there are any remaining remotes (including working ones), Unlock then Lock all doors using the switch on drivers door panel. Within 5 seconds of locking and unlocking doors press LOCK button on the next remote. Your hazard lamps will flash. Repeat this step for each remote (including any working remotes).
6. When all remotes have been programmed turn the key to the OFF position, remove keys from the ignition, unlock doors using the driver's side power lock/unlock switch and open the driver side door. Test all remotes.

My 2002 chevy astro van power door locks are not working. Only the drivers side door will open with the keyless entry. Pushing the unlock button inside the van still won't release the other locks. What can...


i can help , kinda, i had trouble with my astro van door lock in the back , it is not connected to the electric door locks , turns out the thing was broke inside, i had to pry off the inside panel and reach inside the door itself to unlock it, this can be done without damaging the panel or trim but you have to unscrew some parts, and work it loose very gently, on the rest of it, well i have been having trouble with the door locks on my astro, i think its just a weakness in design on these guys

Looking for location of bcm on 97 astro van dash


The BCM is located immediately above the heater controls inside the dash on my 2004 Astro. I know it controls the headlights and locks but not gauges. Haynes says the gauge fuse supplies it power....but I'm not going to bank on that one.

Need location of power door lock relay on 2002 Astro. If someone knows, can you please help?


If your door locks are not working and your cigarette lighter is also not working the fuse is burned out. On my 2001 astro van it is #13 in the fuse box under the steering wheel. I have replaced mine and so far no problems. Good Luck.

How can i program the key less?


  1. Close all the vehicle doors.
  2. Insert the ignition key into the ignition lock cylinder.
  3. Press and hold the DOOR unlock switch.
  4. While holding the DOOR lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
  5. Release the DOOR unlock switch. The doors will lock and unlock to confirm the program mode.
  6. Press and hold the LOCK button and the UNLOCK button simultaneously on one keyless remote. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
  7. Repeat the previous step to program up to four transmitters.
  8. Turn the ignition switch to the RUN (one more click forward) position in order to exit the keyless entry transmitter mode.
  9. Operate the transmitter functions in order to verify correct system operation.

2004 chevy astro clicking in door locks during accelleration and interior lights flickering is sync


We got the problem to settle down for awhile by cleaning the lock contacts on the back slider. They didn't appear to be making a good connection, even when the door was closed tightly. It's just started doing it again, so I suspect the contacts have gotten corroded again.
