My locks and windows stopped working on my 2004 Nissan Maxima. When pressing lock button I hear BCM clicking. Windows do nothing. When putting a test light on gray or grn/yellow wires windows start working and locks will lock or unlock depending on which wire is tested. Once tester removed nothing works.

If none of the power buttons on your 2004 Pontiac Grand Prix are working, it could be caused by a few different issues. Here are a few possible causes and solutions: Fuses - There may be a blown fuse related to the power windows or door locks. Check the fuse box and replace any fuses that are blown.Relay - There may be a relay that controls the power windows or door locks that is faulty. A mechanic will need to diagnose and replace the relay if necessary.Wiring - There may be a problem with the wiring that connects the buttons to the power windows or door locks. A mechanic will need to diagnose and repair or replace any damaged wiring.Switch - The switch that controls the power windows or door locks may be faulty. A mechanic will need to diagnose and replace the switch if necessary.Body Control Module (BCM) - The BCM (Body Control Module) may be faulty which controls the power windows and door locks, and other features on the vehicle. A mechanic will need to diagnose and replace the BCM if necessary.It's important to have the vehicle inspected by a qualified mechanic to diagnose the problem and perform the necessary repairs. Some of the issues can be easy to fix, but some require more extensive repairs and knowledge of the systems.
chances are your window regulator just broke on you. usually the plastic clips break off. Im not sure if you can just replace the plastic clips or have to replace the whole regulator. go into a nissan dealer parts dept and have them pull up a diagram of the drivers window. it will give you a very good diagram of what the regulator looks like. hope this helps!
The locks don't work from any switch or just the driver's door switch ? The door locks are controlled by the BCM - body control module , that's were the clicking you hear is coming from there are no fuse's that are marked for the locks , fuse's for the BCM .
Door Lock System Components
The power door lock system consists of the following components:
• Driver door lock switch -- Uses a single signal wire for both lock and unlock switch activations
• Front passenger door lock switch -- Uses a single signal wire for both lock and unlock switch activations
• BCM -- Class 2 module which requires programming when replaced
• Reversible door lock actuators in each of the doors
• BCM PWR 15A fuse -- Located in the BCM fuse panel, supplies power for the door lock system
The BCM PWR fuse supplies battery positive voltage to the BCM for the door lock system.
The BCM supplies and monitors a reference voltage to the door lock switch through the door lock switch lock/unlock signal circuit. The door lock switch also receives a constant ground source. If a door lock switch is placed in the lock position, the reference voltage is taken directly to ground and the BCM senses 0.0 volts on the signal circuit. If a door lock switch is placed in the unlock position, the reference voltage is taken to ground through a 15k ohm resister that is internal to the door lock switches and senses approximately 2.9 volts on the signal circuit. This is how the BCM determines what portion of the door lock switch was activated.
The BCM, upon receipt of a door lock switch lock or unlock signal, will switch the appropriate door lock actuator control circuits to battery positive voltage. The opposing side of the door lock actuators are connected to ground internally within the BCM through the other door lock actuator control circuit and the doors will lock or unlock appropriately.
Vehicles without keyless entry have two internal drivers in the BCM to control the door lock actuators. All door lock and all door unlock. Vehicles equipped with keyless entry have three internal drivers in the BCM. Driver door unlock, passenger door unlock and all door lock. This is done to isolate the driver door lock actuator so it can be unlocked by itself using the keyless entry transmitter.

Im no professional but i did recently buy a 93 maxima and i have the same security alarm problem and my powered locks dont work at all. im taking off the door panel today to take a look and see if the alarm sensor is loose or damaged, if it is, ill probably just disconnect it. one thing i have noticed though is that when i hit the lock or unlock button, i hear a faint click from the dashboard area which im assuming is the solenoid on a transistor which would mean that the buttons work but the transistor isnt delivering power. Semi-Solution for Locks: Listen for very quiet click when you lock/unlock doors, if you hear it, uve got major work to do, if you dont, then take apart the door and check the switch connections. Semi-Solution for Alarm: take off the door panel and disconnect the sensor.
