2002 Pontiac Grand Am

Hey Brandon,

I have seen various sources on this that range from a bad body control module, a bad driver's door switch and wiring problems. I don't have a magic bullet for it.

All cars have their problems, not just pontiac, I share your dissappointment in the qulity of manufacturing and engineering.

If you are not strong on the elctrical side, you'll need to have it tested. It isn't a computer (pcm) problem or a matter of clearing codes. You can try disconnecting the driver's door switch and see if it stops. If so, then replace the switch.

I don't don't that you can "plug and play" a used BCM, never tried it. A junk yard may be able to provide you with that info. When we replace them, they need to be programmed to the car and the the passlock anti-theft also need to be programmed. Both of these procedures require a scanner to do this.

The door lock switch is in the accessory panel, you can remove it then disconnect it. Check the BCM connector make sure it's tight and clean with no corrosion on it.

How easy is it? Depends on the person, it's relative. I'll tell you this much, "You are smarter than you think you are".

I check them by swapping them with another one of the same. After looking at the diagram, I can see why the switch isn't the problem as the switch contols the ground of the circuit. Somthing is causing a ground to happen, chaffed wire possibly, relay?

Sorry, I meant to send it to you, I'll do it tonight. I was a little preoccupied. I am more inclined to think that a wire has rubbed against a grounding point and it when it moves a little it grounds the circuit activating it. I would try to swap the relays for the heck of it becasue its quick and easy. IF no luck I would try wiggling the harnesses of that circuit.
