What fuse controls the locks on 2003 galant?

turns fail. 2003.?
so did not check all fuses first then scan the OBD2 port next
ooops, why skip those?

lots they are what do they all do good and bad.?
well fuses are blown why skip step on, electrics, all fuses checked,
"changed flasher"<<, why say that. then not say turns and hazards fail too or not????? i have a real oem shop manual for this car. USA spec car is it>?
w cant guess countries of VIN to know it
chapter 8w wiring, is clear and easy to read.

8w-60 and 61 locks and windows. schematics and all
not the fuse for windows it runs both sides. F12 , 50amps.
do door locks fail using key fob??????????? any?
F12 also runs door locks but is not bad. only for 1 door.

right door inside lock controls dead?too?
you have a fob
and lots of door controls switches, it is clear which fail and do not
front and rear, both.

the door control modules on this car use COMM buse
called PCI serial bus this car
so commands from any in car button or fob must work and send commands to t the door commanded, via PCI bus.
same goes for windows ,door control modules

bad comms
or the origination command device fails, the FOB or the door buttons afail
all doors have controls do only right side fail and fob too?

try testing at all doors first
and the fob too.
off hand seems PCI bus wires damaged on the right side.

Power windows don't use fuse's , has circuit breakers
• PWR WDO CB 25A (fuse block) (System power for left and right windows 2-door vehicles. System power for LF and LR windows 4-door vehicles)
• PWR WDO CB 25A (IP wiring harness junction block) (System power for RF and RR windows 4-door vehicles)

Door Lock System Components
The power door lock system consists of the following components:
• The driver door module (DDM)
• The passenger door module (PDM)
• The body control module (BCM)
• The driver information center (DIC)
• The rear door lock switch
• The door lock relay
• The door unlock relay
• The liftgate lock relay--utility vehicles with liftgate only
• The reversible door lock actuators in each of the doors and liftgate
• LOCKS 20A fuse (rear lock/unlock relay supply voltage)
• ECC 10A fuse (liftgate lock relay supply voltage)

First check fuse #14 & #19 in the under hood fuse/relay box. If either is bad, replace the fuse. This may fix your problem. Each power lock actuator [solenoid motor ] has a built in circuit breaker. The actuators are controlled by the BCM [Body Control Module, aka Body computer] To do further troubleshooting will require a computer scan tool.

I checked all the fuses and relays and all are in good shape???????
Did you check the correct one's ,that's the question ? And did you use a voltmeter or test light to check across the correct fuse's ? And how did you check the relay's ????? Videos on youtube on how to test a relay ! And using a wiring diagram or power flow diagram that shows all componets of the none working systems ., Plus you need to know how the thing's work . Data communication network is involved in the working of these thing's , Data messages from module to module !

The body control system consists of the following 3 modules:
• The Dash Integration Module (DIM)
• The Instrument Panel Module (IPM)
• The Rear Integration Module (RIM)
Rear Integration Module (RIM)
The various RIM inputs and outputs are described in the corresponding functional areas as indicated on the RIM electrical schematics.
The RIM functions include the following:
• Automatic level control
• CIGAR relay control
• Class 2 communication requiring RIM interaction
• Content theft deterrent
• Fuel door control
• Fuel level sensor input
• Heated seat control
• HVAC blower control
• LK/CYL relay control
• Park brake relay control
• Rear defog relay control
• Rear park assist chime control
• Retained accessory power (RAP) relay control
• Reverse relay control
• Transmission shift inhibit
• Trunk release relay control
• Various controls for the interior lamps

Just looking at fuse's and relay's isn't enough ! Hooking up a factory scan tool an checking for DTC'S - diagnostic trouble codes in all the vehicle control modules is always the first step . Which fuse boxes did you check ? Do you know there is a fuse box under the back seat ?
Fuse Block - Rear
Left rear of the passenger compartment, under the rear seat !
The vehicle is equipped with power door locks. Each lock actuator is powered and controlled by the door module mounted in the individual door, but the rear integration module (RIM), which is the master control for the door lock system, determines when the lock functions are permitted. The RIM receives and examines the requested lock function from the individual door modules, or from the remote function actuator (RFA) via the class 2 serial data circuit. The RIM also examines the transmission shift selector position and the ignition switch position information available over the Class 2 serial data circuits. If the RIM determines that a lock or unlock function is permitted, it sends a class 2 message back to the individual door modules commanding them to perform that Lock or Unlock function.
Your best bet , take it to the dealer !

A part inside the door known as the "Door Ajar" sensor switch is defective, replace it. It is attached to the door latch in most makes

Check your power door lock fuse located underneath the drivers side steering wheel. Flip the fuse box cover over and there will be a diagram showing what fuse controls what component. When it burns out the power door locks will no longer work. If your fuse is ok then replace your power door lock actuator has gone bad. You will then need to remove your door panel and replace the PDL actuator with a new one.

it is likely a relay in the fuse panel under the dash. feel the tops of them as you have someone try the power locks or windows if that is not working. the relay should click or become very hot.

it sounds as if the wiring harness to the door may have come disconnected or broken you have to open the door panel and check the connections manually

needs a new door lock actuator usally built into the door latch

Replace the doors.
