Driver's Door Electronic Lock Actuator 2003 Grand Prix GT
I bought this car new in April 2003, it's always garaged, rarely sees rain, and only has 32,000+ miles to date.
She's absolutely like new, and You'd be hard pressed to find another in this condition....near mint, inside and out.
Every so often the lock actuator on the driver's door fails to function with the electronic door or key FOB controls.
This issue has been ongoing since the car was 2-1/2 years old.
I took the car to the dealer some 3 times for this issue, and they could not replicate the problem...always seemed to work fine for them.
About 3 years ago at the urging of a friend who's a GM mechanic, I checked all the wiring and switches (4 doors) for proper connections/shorts etc, plus, I ordered and installed a new GM actuator, yet the issue continues to this very day.
It's an intermittent problem and sometimes the locks work great for days, then suddenly, the issue crops up again.
Here's a fly in the ointment: sometimes the actuator refuses to lock the car using the master door control or the key FOB, but if the car is started (with the doors closed) and put in gear, the actuator will lock down all 4 doors....then other times, the other 3 doors lock down and the driver's door won't.
Sometimes the actuator can be persuaded to work by repeatedly rocking the master lock switch, other times, it's no go.
Any input, GM folks???"I Hate When That Happens!"

If you have replaced the actuator , i would maybe explore the switch. The actuator you bought had a one year warranty and I would have taken it back to see if maybe it was bad.
I have replaced 3 of the 4 actuators on my 2008 Sierra, and the part for your car looks identical to mine!
Who replaced it last time, maybe it didnt get replaced? Sometimes the rod that runs up and sticks up out of the top of the door for the lock(has that plastic do-hickey on the end of it) gets bent and hangs up inside the door also.
I had the same symptoms on my drivers door and i replaced the actuator which resolved the problem.

Did you have a case with customer assistance regarding your concern? Do you have a case number? I can also look into this issue further. In order to do so, I will need some more specific information from you. If you could please send me your full name, address, phone number, the VIN for the vehicle, and current mileage, I will be able to take further steps. If you have further questions, please feel free to contact me directly. Thank you.

Switch works fine....all the other 3 doors engage, and I replaced the acutator with new, so I know it was replaced.

This late in the game, I really cannot believe they'd repair the lock issue.
Where to send the info?
BTW: two different dealers did the same thing with My Chevy Suburban when I kept getting a check engine light.
Turn the trouble light off before the vehicle enters the shop, and away it goes.

There is a transmitter that sends the signal to the door locks from the FOB that could be bad...but I would think it would affect all the doors. My guess is its something simple that is getting overlooked.
