05 G35 Coupe Door locks need to charge to work??

Hi All,

- I'm working on an 05 G35 Coupe with a strange issue..
- Door locks work but only about every 45 seconds or so, no matter if I use the remote or the lock / unlock button inside the car.
- First thought is it's the door lock actuators, BUT I don't think so cause they do work as long as I let them rest for about a minute in between uses. I can hear something that sounds like it's coming from the rear passenger area behind the interior panel like maybe a relay or something that feeds the locks that sounds weak?
- But I'd compare it to a camera flash or a capacitor that needs to charge for a minute in between uses and then it works but if it's used right away it's too soon.
Anyone have this issue? Any solutions? Does this even make sense lol?

Could be indication of a failing body control module (BCM). Start with the troubleshooting steps in the FSM, digital multimeter on the harness for the lock actuator and see if it's actually receiving a signal.
