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 !

Electric windows not working but locking the doors when you push it


Had the same issue, both doors controls stopped working at the same time making the power windows, power mirrors, and power door locks all stop working. However, when the engine was off the door lock would work. It could be many things, but the fact that they all quit working at the same time suggested it wasn't an individual motor. I pulled the door main control panel and with a wiring diagram checked the continuity of each switch through the electrical plug out back. You can get the diagram off kiatechinfo.com

The main door control turned out to be good (expensive part). It wasn't getting power to the control, which meant it was either a broken power wire or a bad ground interrupting the circuit. The easiest to test was the ground. I ran a small wire from the negative battery and put it in the main ground wire on the back of "main door control panel". Worked perfectly on both doors. Apparently the ground for the door accessories are somewhere on the floor board, they corroded from a leaking sunroof. Never could find the bad ground so i just ran a new ground wire to it from the engine (drill a screw into body and attach wire)

Electrical wiring diagram for door lock


Try "clearing the cache" by removing the negative battery cable for a few minutes. Before doing so, be sure you know how to reset the clock and radio codes & presets.

Electric door locks


First off you need a Chiltons manual for that specific vehicle. As for the wiring, I would venture a guess as to they are not present, but you may get lucky when you snatch off the door panels. Lastly, you can find electric door looks in the JC Whitney catalog, but its gonna cost you, but if you do it yourself, less than what an aftermarket shop would cost you. Good luck.
