Where is the body control module on a 2001 pontiac sunfire located and doess it have a fuse

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.

puddle fuse ???? Puddle light's on door rear view mirrors ? I can't find the center instrument fuse box ? Doesn't have one in the center . Has two - one right an one left
Fuse Block - Right I/P
On the lower right side of the I/P
Fuse Block -Left I/P
On the lower left side of the I/P
These are not what your looking for any way .

Exterior Courtesy Lamps
The SEO 1 15 A fuse in the engine wiring harness junction block supplies battery positive voltage to both the exterior courtesy lamp relay switch contacts and the exterior courtesy lamp relay coil circuit. When the driver or passenger door is opened the body control module (BCM) energizes the exterior courtesy lamp relay. Current flow is from the exterior courtesy lamp relay to both outside rear view mirror exterior courtesy lamps. The exterior courtesy lamps are grounded at G200 and G203. When the remote function actuation (RFA) module receives a door unlock command from the remote function actuator transmitter, the RFA module will send a message to the body control module (BCM) indicating that an UNLOCK command has been received. The BCM must have inputs that indicate that the ignition switch is OFF, all the doors are closed. The BCM will activate the exterior courtesy lamp relay illuminating the power outside mirror exterior courtesy lamps. If the door locks are activated to the LOCK position, or if the ignition switch is turned to either the ON or RUN position the exterior courtesy lamps will deactivate immediately.
When an outside door handle is lifted or a door is opened, the exterior courtesy lamps illuminate.
I would think maybe a relay problem , not a fuse . The exterior courtesy lamps relay , located in the relay block body . Relay Block -Body
Under the left side of the instrument panel near the left kick panel
If this doesn't fix the problem you need to have a qualified repair shop that has a factory or professional type scan tool view code's in the BCM - body control module .
DTC B2643
The SEO 1 15 A fuse in the engine wiring harness junction block supplies battery positive voltage to both the ground illumination relay switch contacts and the ground illumination relay battery positive voltage circuit. When the driver or passenger door is opened the body control module (BCM) energizes the ground illumination relay. Current flow is from the ground illumination relay to both outside rear view mirror ground illumination lamps. The ground illumination lamps are grounded through the courtesy lamps relay at G200 and G203.
DTC B2642

Door locks fuse 20 amp - location , instrument panel fuse box .
Fuse Block-I/P
Right side of the IP, in the right front door opening

Doubt fuse is the problem , door lock's are controlled by the BCM - body control module .

Do you know anything about automotive electronic's , control module's ? Serial data communication networks ?
Circuit/System Description
The driver and passenger door lock and side window switches are integrated control module switch assemblies. The DDS and PDS door lock switches are normally open, 2 position rocker type switches, with detents for lock and unlock. The DDS and PDS are directly connected to the respective door lock actuator through the door lock actuator control circuits. When a door lock or unlock function is activated from the DDS or PDS, a serial data message lock or unlock command is sent to the other door switch and body control module.

KEY FOB PROGRAMMING INSTRUCTIONS
Transmitter Programming
No Tools Required
In the event that a transmitter is lost, program the old & the new transmitters into the memory of the remote control door lock receiver. Up to 4 transmitters may be programmed.


Important
Once the keyless entry receiver enters the programming/diagnostic mode, the programming of the first transmitter erases all previous transmitter programming information. You must then program all of the transmitters.

Program only 1 vehicle remote control door lock receiver at a time. If u program multiple receivers simultaneously, the same transmitter could possibly be programmed to more than 1 remote control door lock receiver.


Perform the following steps:

Sit in the vehicle driver is seat. (actually it’s much ezr from the front pass seat)
Remove the ignition key from the ignition lock cylinder.
Close all of the vehicle is doors.
Remove the MALL PGM fuse from the fuse panel. Refer to Electronic Diagnosis in Body & Chassis.
Turn the ignition lock cylinder to the ACC position.
Turn the ignition lock cylinder OFF, then back to ACC within 1 second.
Open & then close any vehicle door. You will hear a chime when the remote control door lock receiver enters the programming/diagnostic mode. If u do not hear a chime, start again at step 1.

Important
After 7 seconds, you may hear a chime confirming successful synchronization. After approximately 14 seconds, you will hear a chime confirming successful programming.


Press & hold the transmitter LOCK & UNLOCK buttons simultaneously for 14 seconds.
Repeat step 8 in order to program each additional transmitter.
Remove the ignition key from the ignition lock cylinder.
Install the MALL PGM fuse back into the fuse panel. Refer to Electrical Diagnosis in Body & Chassis.
Validate that all the transmitters that were programmed operate properly. Refer to Keyless Entry System Operation

Hope this help (remember comment and rated this).

anything related to headlamps, instrument lights, door locks, etc... is typically related to a separate module called the BODY CONTROL MODULE (BCM)
