2002 Pontiac Grand AM: Power Door Lock Remote Will Not Get Programmed?

The power door lock remote got faulty.Due to this new remote was bought from dealer.But to make the new remote work,the remote has to be programmed.If the Remote is not getting programmed,then it will not get detected.In this case it can be faulty remote itself or its the Issue with BCM or Anti theft system.

first on the remote you bought, is it a genuine GM remote, or some aftermarket brand? I have seen several aftermarket ones on Ebay and such that dont work.
So Always by original factory remote from Dealer.


As per the  power door lock diagram, bcm and antitheft diagrams. Because of how the circuits are run, even if one door lock actuator or switch was faulty, the other side would still work. The only common denominator between them not working and the remote not being able to be programmed is the BCM. Other then this nothing else will cause all the current issues.

Replacing the BCM will resolve this.


To replace the BCM its easy,the Procedure is as follows:-----


For this you will have to  remove the right side trim panel underneath the right side of the dash and it is mounted on a bracket attached to the side to where the blower motor bolts to:

See the help diagram and instructions  shown below:-----

Replacing BCM

Please Note:----
It has to be programmed with your current mileage and VIN code and used one will work as long as it is programmed first with your vehicle's information.

This details will help.
Thanks.

Low beam Headlights shuts off after few minutes on 2006 Buick LaCrosse?


If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.


This problem is not very common,but some users have noticed this problem
Check out the details below for troubleshooting the issue.

It sound like faulty drl relay or low beam relay.check in the owners manual in dash for relays locations.in case you get caught dark on the way home you can use head light switch manually control head lights it will turn on head lights to get you home.


Possible areas to suspect must start from the DIP switch which is the cluster switch, the relays to the headlamps and the headlamps assembly /holders and ground to the assembly.
You can confirm only when tthe fault appears and I suspect that the fault will come by when the headlamps are switched on for a while. It might heat up any of the switches , the relay points or the holder contacts as a POOR CONTACT will heat the joint and so cut off voltage or deliver low voltage due to the resistance develeoped on the heated joint.
Use a 12 volt test lamp to test the circuits when the fault appears or a multimeter to confirm the flow of voltage when the fault comes up.


I recommend you replace the low beam relay in the box under the hood. Relay #35 as marked in red circle below.




But if all checked ok,then it can be problem with BCM.BCM means Body Control Module.
It is necessary to understand that your headlamp circuits are controlled by the Body Control Module (BCM) in your vehicle. Your headlamp switch is actually a very low voltage input device to the BCM. I think your BCM may be losing the input data from the headlamp switch, thus switching the headlamps off.

This details will help.Thanks.
