2012 ford f350 door locks only work manually key fob has been dead for years now door lock button does not work cant seem to find fuse location in my book ?


None of the door power lock's work ? Not from any switch ? F32 - 15 amp fuse location - body control module (BCM) . Probably not a fuse issue , door locks are controlled by the BCM controlling relay's located inside the BCM . This relay's are PCB - printed circuit board relay's , non serviceable . Your best bet , take it to a qualified repair shop .

Power Locks
The Body Control Module (BCM) monitors the door lock control switches. When the BCM receives an unlock/lock command from either door lock control switch, the BCM energizes a relay (internal to the BCM ) to supply the correct power and grounds for the door lock actuators.

Remote Keyless Entry (RKE)
The Remote Keyless Entry (RKE) feature is controlled by BCM . The BCM receives the RKE inputs from the Tire Pressure Monitor (TPM) module over the Medium Speed Controller Area Network (MS-CAN) . When any RKE transmitter button is pressed, the signal is received by the TPM module internal antenna. The TPM module then filters the RKE signal received to make sure it is a programmed transmitter. If the signal received is from a programmed transmitter, the TPM module sends the RKE command to the BCMover the MS-CAN . The BCM then interprets the RKE command and activates the corresponding output.
The BCM requests the illuminated entry feature to turn the interior lamps on when an unlock command is received. If a lock command is received, the illuminated entry feature turns off. The BCM then supplies voltage to the appropriate door lock actuator(s) to lock or unlock the doors. The RKE transmitter can also be used to activate the panic alarm. On vehicles with memory, the RKE transmitter also causes the BCM to send a MS-CAN message to the Driver Seat Module (DSM) to activate all memory features to the positions associated with the RKE transmitter being used.

    Where is the power lock relay for 1996 Saturn SL located. My door lock spoturing and it maybe the cause of battery draw.


    The various electrical relays in most cars are in fuse and relay boxes located under the hood. There are usually diagrams on top or underneath the boxes which show what each component does.

    The remote unlock for my 2000 Jetta no longer works on the driver door. It unlocks the other doors and pops the trunk. Is it the lock? I have to use the key to unlock the drivers door.


    First thing to do is check for a burned out fuse. If that is not the problem, then check for a defective relay. A lot of newer cars, including VW's, use relays for several things, including the power door locks. If you have the owners manual, the location of the fuse and relay box should be in there. If not, try to find a repair manual, or an on-line repair manual such as All-data or Mitchell on-line. If the problem is not the relay, then the problem is either going to be in the control module that recieves the signal from your remote and sends the command to lock or unlock your doors, an open in the wiring, or both lock solenoids went bad on you. As a reminder, always use caution when working on electrical systems, ans accidently shorting out something could cause a lot of other problems.

    My 2002 astro van door locks will not fully operate. I replaced the door actuator on the passenger side, but now the driver's door won't work, the hatch is stuck shut on one side, the headlights will...


    On repairing door locks first check the cigarette lighter and see if it works, the door locks gets it power on the same fuse. If good,you then need to check if 12VDC is at each of the actuators when pressing the switches for the locks. If no power is not at the actuator you should suspect the power lock relay to be defective. This relay is located beneath the steering column within a major cluster of connectors and is located within a bank of 3 relays located within a covered housing. These 3 relays are identical and you can temporaly reverse them to see if this will solve the problem. If it does, GM's part # is RY-232. Can't help you on the rest.......sorry!
