Question about 2002 GMC Sierra
*** the passenger door actuator that locks and unlocks the door is bad. So have to order that on Monday
The truck's probably been disabled by the security system. that may involve a trip to a dealer to set right.

SOURCE: Hi, I have a 2003
I have a similar problem. The remote sometimes opens all doors, and other times it will only open the 2 rear doors. Once inside the vehicle, the driver side window controls intermittently operates all windows and doors. It has no effect on the 2 rear doors, as the window controls still work. This behavior happens intermittently while driving the vehicle.

I would check for vacuum leaks, maybe intake or brake booster

could it be the A/C pump kicking in. might be boging down the motor or electrical circuit, not letting the injectors get enough power. This could happen if the bearings are going bad in th A/C pump or there is a short in it. Just an idea. sounds like you have done the main components.

The theft light issue is a good observation. Have you replaced the key tumbler or an ignition component lately? Has there been a lightning storm close very recently?
What the flashing security light is indicating is an attempt to relearn the key you are using.
Turn the key to run position, allow light to flash for 10 minutes, when light stops flashing turn ignition to OFF position for 5 seconds, turn ignition to run position and start over. Do this for 3 consecutive cycles, the the theft system will relearn the key cylinder code and store it once again.
Try that first before you go any further.
Let me know what you find.

Could be the latch mechanism for the door is sticking. You could try using some white grease on the latch and the contact where the latch hooks to. You can purchase the grease from most auto parts stores. You will not need to use alot. Just apply a small amount to the mechanisim and then work it in using the manual handle. Then open and close the door several times to feel the "action". Then apply a little more and repeat. This should loosen the latch and get it working again. Also make sure that none of the tension springs have come loose on the latch. And check the seal around the door and make sure it is not pinched and has a proper fit.
