1998 nissan quest door lock intermitant problem

The body control module is responsible for controlling various electrical functions in a vehicle, including door locks. Removing the 50-amp fuse could have caused the module to reset, which may have resulted in the driver side door becoming locked.
To resolve the issue, try the following steps:

1. Turn the vehicle off and remove the key from the ignition.
2. Close all doors, including the driver side door.
3. Lock the vehicle using the key or remote.
4. Wait for a few seconds, then unlock the vehicle using the key or remote.
5. Check if the driver side door is unlocked. If not, try using the key or remote to lock and unlock the door again.

If the above steps do not work, there may be a problem with the body control module or the door lock actuator. In this case, it is recommended to consult a certified mechanic for further assistance.

It may be that water/moisture has gotten in behind the door panels...do you notice that it worsens in damp(er) weather? The car unlocks by itself if you leave the key in the ignition and you try and lock the doors.

Or somebody has the same coded fob (unlikely).

You might want to reprogram the remotes if you determine that the area behind the door panels is dry and there are no corroded wires, etc.

Good Luck.

2004 Nissan Quest Remote Programming Note: You must have all remotes on hand when performing this procedure. Any remotes not used during this procedure will become inactive.
1. Close and lock all doors with the driver's side power lock switch located on drivers door panel.
2. Insert key into ignition (DON'T TURN) and remove it from the ignition key cylinder at least 6 times within 10 seconds (this will need to be done at approximately one second intervals). You may need to insert and remove the key up to 10 or 12 times until your hazard lamps flash. PLEASE NOTE: Withdraw key completely from ignition cylinder each time. If this procedure is performed too fast or too slow the system will not enter programming mode.
3. Insert key into ignition and turn to the ACC position.
4. Within 5 seconds, push the LOCK button on the keyless remote. Your hazard lamps will flash. PLEASE NOTE: Do not press the button on the remote more than one time or the programming will not be successful.
5. If there are any remaining remotes (including working ones), Unlock then Lock all doors using the switch on drivers door panel. Within 5 seconds of locking and unlocking doors press LOCK button on the next remote. Your hazard lamps will flash. Repeat this step for each remote (including any working remotes).
6. When all remotes have been programmed turn the key to the OFF position, remove keys from the ignition, unlock doors using the driver's side power lock/unlock switch and open the driver side door. Test all remotes.

sounds like the actuator in the door that locks and unlocks the door is jammed or too weak to move the lock assembly to fully lock/unlock positions. the linkage may be in a bind that can cause the same problem.

fuel pump pressure may be low. should be 40 psi. Also see TSB on self locking doors. It fixes about 1/3 of them.
