Power comes from the fuse block to the door switch , to the actuator. remove the inner door trim panel to access the harness.

07grandprix my door locks are all actin up sometimes they work & sometimes they dont I can set the alarm even tho they wont lock & the alarm goes off if u open the door but won't lock with the key/pad


The Power Door Lock System is controlled by the body control module (BCM) and can be activated by any one of the following
?€¢
A door lock switch lock or unlock actuation.


?€¢
A door lock cylinder switch unlock actuation.


?€¢
A keyless entry transmitter actuation.


?€¢
An automatic door lock actuation (Personalization function).


?€¢
An automatic door unlock actuation (Personalization function).


?€¢
A last door closed locking (LDCL) actuation (Personalization function).


Door Lock Operation
When the body control module (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 body control module (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 left front (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).
Faulty electrical connections or wiring may be the cause of intermittent conditions. Refer to Testing for Intermittent Conditions and Poor Connections.
A factory scan tool would help for checking inputs from the door switches to the BCM ! You could do it with out scan tool , a lot more work involved ! Need a wiring diagram an a component location chart an wiring harness routing diagram !
Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items:
?€¢
Wiring broken inside the insulation


?€¢
Poor connection between the male and female terminal at a connector


?€¢
Poor terminal to wire connection--Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself, and corrosion in the wire to terminal contact area, etc.


?€¢
Pierced or damaged insulation can allow moisture to enter the wiring causing corrosion. The conductor can corrode inside the insulation, with little visible evidence. Look for swollen and stiff sections of wire in the suspect circuits.


?€¢
Wiring which has been pinched, cut, or its insulation rubbed through may cause an intermittent open or short as the bare area touches other wiring or parts of the vehicle.


?€¢
Wiring that comes in contact with hot or exhaust components


?€¢
Refer to Inducing Intermittent Fault Conditions in order to duplicate the conditions required, in order to verify the customer concern.


?€¢
Refer to Testing for Electrical Intermittents for test procedures to detect intermittent open, high resistance, short to ground, and short to voltage conditions.


?€¢
Refer to Scan Tool Snapshot Procedure for advanced intermittent diagnosis and Vehicle Data Recorder operation.


You should take it to a ASE certified repair shop if not familiar with Automotive electronics !

Power door locks keep unlocking, and then when unlocked they keep clicking to unlock repeatedly, the car will not stay locked and had to disconnect the battery to keep it locked and so not to need a jump...


it could be a shoted wire to ground going to the door lock actuators or a bad door lock actuator.

Disconnect all door lock actuators & see what happens, If ok, connect one at a time and see which one acts up.

1999 Chevy Tahoe Door wiring diagram


I am not sure exactly where to get your info for free, but have another solution. The drivers door holds all you need. The door panel needs to be removed and then reconnect the power door lock switch. Then just locking and unlocking the door will trigger the actuator to move, allowing you to find it and the wires connected to it. Disconnect the wires and plug in a Digital Multi-Meter into the plug on the wire end and hit the lock and the unlock buttons to find which polarity to which wire unlocks the door and to lock it would be in reverse. Then he can wire the keyless entry into the truck via these wires and can use wire-taps which will pop over the wires in the truck and allow him to add the keyless entry w/o cutting wires. :D Have fun

1997 villager just started locking the doors automatically


This is a common issue. You have poorly adjusted inside lock rods, or water in your door lock actuator connector behind the door trim panel , or you need to cut one wire in the driver door wire harness to defeat the autolock function. Go here for info on what to do. See files and also links for this issue. http://autos.groups.yahoo.com/group/villagerquest/

Driver door won't lock with key fob


Check the locking solenoid / actuator in the door behind the panel, could be burned out or loose wire. It should take about 20-30 minutes to open, fix it and close the door panel if there's no major problem. Autozone might be able to help out with a solenoid.

My van's doors keep locking by themselves


either you have water in the door lock actuator connecotrs in one of the doors. or a misadjusted lock rod for the inside lock switch or a wire shorting out in one of the doors (for the lock actuator).
This was an issue for earlier models through 1997. If no luck with those, you will have to cut a wire in the driver door lock actuator harness that will eliminate you being able to lock or unlock all doors at once with the key in hte driver door lock cylindr.
