Having problems with your 2004 Saturn VUE ?
Sluggish electric door locks, when actuated, : lock, unlock, lock, etc , they get better.
First thing is to check your battery voltage "before" you start the vehicle. If it reads anything below 12-12 1/2 volts your going to want to check your charging system. This could be the best way of your battery saying I'm getting old. But let's get back to the locks.If you have a little extra time, you can remove the inner door panels and spray white lithium grease on the solenoid rod of each lock solenoid, also hit the linkages while you are in there. The fact that you claim that ALL of the locks are slow to react is why I decided to have you check your battery. It stands all night and you unlock your doors right off the existing voltage, whereas once you're in the vehicle and start the engine, now the locks work better because they are getting full charge voltage from the battery/alternator combo.
Try using white lithium on the locks and remove the door panels to properly see if they are corroded then also spray them also battery power can be an issue a few ideas to start with is the battery in the remote if using one good
