I checked the fuse and it seems to be fine, but first the one the front passenger door lock does not work but the other 3 yes. After changing the passenger's one they stopped working the 2 back. I reconnected the old one that had and the driver and 2 back work again, but that of the passenger did not.

Just so I am clear. The passenger side front actuator does not work. You replaced it and when you plug the new one in, the back two stopped working. Then you reconnect the original one and it goes back to just the passenger side not working. If this is correct, then the replacement actuator sounds like it is shorted or defective in some other way.

Where did you get the part from? What was the part number that they gave you? Just want to make sure it is the correct one.

I took the actuator in a pic-a-part of another Pontiac g6, it is also original. I think something happens with the power because when the old one is connected that does not work the back they work and when I put the one that works the ones of behind they stop working.

Yes. Your instincts are correct that it is a power issue but the part that you are putting on is most likely causing it. I have seen this happen on door switches as well. The fact that the first actuator doesn't work but the rear do and then when you put the other one on the rear stop working just shows that this part that you are putting on is the issue.

I would suggest taking it back and having them swap it out.

I bought a universal one in Amazon for the front of the passenger and it does the same thing. The back 2 stop working. My head is breaking and I don't discover the problem.

So you bought a second new one and it does the same thing? Can you send me the part number of each part that you bought? Maybe just take a picture of the boxes with the numbers.
