Hazard lamps & pwr locks inop

A electronic control module ,BCM body control module or a SJB - smart junction box ford calls their body control module .
Principles of Operation
The smart junction box (SJB) monitors the multifunction switch position by sending multiple voltage reference signals to the multifunction switch. When the multifunction switch is in the LH or RH TURN positions, or the hazard lamp switch is engaged, that input signal is routed to ground.
When the SJB receives a request for a turn signal or hazard lamps, the SJB supplies voltage to the appropriate turn lamps.

• The hazard lamps are inoperative/always on

• Circuitry
• Hazard lamp switch
• SJB

• Go To Pinpoint Test O

Pinpoint Test O: The Hazard Lamps Are Inoperative/Always On
Refer to Wiring Diagrams Cell 90 , Turn Signal/Stop/Hazard Lamps for schematic and connector information.
Normal Operation The smart junction box (SJB) sends a voltage reference signal to the hazard lamp switch through circuit CLS32 (BN/YE). When the hazard switch is engaged, the voltage signal is routed to ground through circuit GD116 (BK/VT). When the SJB detects a request for the hazard lamps, the SJB sends voltage to the appropriate turn lamps.
DTC B1875 - is an on-demand code that sets when the SJB detects a short to ground from the hazard lamp switch input circuit.

Possible Causes
• Circuit CLS32 (BN/YE) open or short to ground
• Circuit GD116 (BK/VT) open
• Hazard lamp switch
• SJB

Turn Signal Lamps
The turn signal lamps are made up of the front park/turn signal lamps and rear turn signal lamps. The front turn signal lamps flash with the rear turn signal lamps when a turn is initiated using the turn signal/multifunction lever. The turn signals will operate only with the ignition switch in the RUN position and will not operate during hazard flasher operation.
When the ignition is turned to the RUN position, battery voltage is supplied to the TURN SIGNAL, CORN LPS Fuse. Battery voltage is then applied through the TURN SIGNAL, CORN LPS fuse circuit to the hazard warning switch. The hazard switch supplies a turn signal flasher signal to the turn signal switch. With the turn signal switch in the LH or RH position the corresponding turn signal indicator, rear turn signal, and front turn signal receive the turn signal switch signal and will flash. The front turn signals receive the turn signal switch signal from the turn signal switch via the body control module (BCM) . The front turn lamps are grounded at G101. The rear turn lamps are grounded at G301 and G302.

The warning chime sounds if the parking lamps (13200) or the headlamps (13008) are left on after the key has been removed from the ignition switch lock cylinder and either front door (20124) is opened. There is a chime module that controls this .
The safety belt warning chime (10D840) (also called the central processing unit or CPU) is an audible warning system and timing circuit. The system components include:

• Timing circuit safety belt switch.
• Dome lamp switches.
• Safety belt warning indicator switch which is an integral part of the front safety belt buckle end (61203).
• Ignition switch (11572).
• Headlamp switch.

The warning chime sounds and the safety belt warning indicator illuminates when the ignition switch is placed in the ON position and the LH front safety belt is not buckled.
Key In Ignition Warning
The warning sounds if the key is left in the ignition switch lock cylinder when either door is opened and the ignition switch is in the LOCK or OFF position.

Here is what the service manual says. Looks like it is not a flasher relay but a function of the body control module.

TURN SIGNAL AND HAZARD WARNING LAMP SYSTEMSystem Description OUTLINE Turn signal lamp and the hazard warning lamp is controlled by combination switch reading function and the flasher control function of BCM.
TURN SIGNAL LAMP OPERATION - BCM detects the combination switch condition by the combination switch reading function. - BCM supplies voltage to the right (left) turn signal lamp circuit when the ignition switch is turned ON and the turn signal switch is in the right (left) position. BCM blinks the turn signal lamp.
HAZARD WARNING LAMP OPERATION BCM supplies voltage to both turn signal lamp circuit when the hazard switch is turned ON. BCM blinks the hazard warning lamp.
TURN SIGNAL INDICATOR LAMP AND TURN SIGNAL SOUND OPERATION - BCM transmits the turn indicator signal to the combination meter with CAN communication while the turn signal lamp and the hazard warning lamp are operating. - Combination meter outputs the turn signal sound with the integrated buzzer while blinking the turn signal indicator lamp according to the turn indicator signal.
HIGH FLASHER OPERATION (FAIL-SAFE) - BCM detects the turn signal lamp circuit status by the terminal current value. - BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal lamp operating. NOTE: The blinking speed is normal while operating the hazard warning lamp.

It's part of the hazard switch. have to take trim panel off to replace it .Apply the parking brake.
If the vehicle is equipped with a column shift, position the transaxle shift control indicator to 1.
Adjust the steering wheel for access.
Using a small, flat-bladed tool, gently remove the bezel from the ignition lock cylinder.
For the Impala, remove the right and the left access covers from the instrument panel (IP) fuse block.
For the Monte Carlo, remove the left access cover from the IP fuse block.
Remove the steering column filler. Refer to Steering Column Opening Filler Replacement .
For the Monte Carlo, open the instrument panel compartment door.
Remove the trim plate screws from the IP cluster.
Start at the left side of the IP cluster trim plate. Grasp the trim plate and carefully pull rearward. Disengage the IP cluster trim plate in order to easily access the hazard warning switch
Disconnect the electrical connectors from the hazard warning switch.
Remove the hazard warning switch from the IP cluster trim plate.
