i do not know where it is but give these guys a try they sells only GM-parts only its Schram auto & truck parts 1-800-292-1032 and they website is www.schramauto.com if all fails stop by a cadillac dealership in the parts department and they be able to tell you sorry wasn't able to help you Michigan Man
I had the same problem with my CTS. I took it to my car guy andhe could not get any codes, so he took it to a tranny guy and he had the same problem. I finally took it to the dealer,, and the Power Control Module was bad. It is under a recall for ten years 80,000 miles
I personally have not had this problem but if you look in your owners manual there will be a section that will tell you exactly where and what fuses and the size of them do as well as the relays and there jobs as well. also in the fuse block there should be a little pare of tweezers and spare fuses or you can take the blown fuse to any auto parts and they will be able to give you the right good fuse if problem persists check and see if something is stuck like cd or a blown speaker hope this helps good luck
Look for a plastic plug directly under key in bottom of column. Under plug is a switch take small philips screwdriver & push on switch while turning key backward to take out.
If the steering will lock is on take pressure off the lock by turning the steering wheel one way or the other. Otherwise if it just jams up oil the hole where the key goes then this will help the tumblers from getting stuck. Next would be have a new key made. If that doesn't do it replace the lock. Good luck.

54,engine bay fuse blows
only a service manual shows what all fuses connect to , in total.
only
so I read that now to you.
hummm all fuses in the SM have names not numbers.
the lid to fuse box usually has name. of the fuse.
ok only the users guide shows fuse # and 54 is clearly named
there as, POWER MODING.
AND IN FACT IS ONLY A TINY 2AMP FUSE.
THIS FUSE GOES 2 PLACES
1: IGNITION SWITCH PIN2
2: TDM THEFT DETERRENT MODULE. PIN 1.
YES GOES TO BCM PIN X1-14 , KEY ON, ONLY.
YOU WILL HAVE TO PULL MODULES, TO SEE IF MODING FUSE
HOLDS AND NOT BLOW.
I'D PULL TDM FIRST

Is the security light on in the instrument cluster ? Sounds like anti-theft system problem . The anti-theft does not disable the fuel pump ,turns off the fuel injectors , nor does it disable the starter . So it's probably not the anti-theft system . Your best bet (if you know how ) test power and ground circuits using voltage drop testing , hook up a professional scan tool an do a full system scan of all the modules on the vehicle . Your probably not aware of the sophisticated electronics on that vehicle . BCM - body control module ,Immobilizer Description and Operation
The immobilizer system functions are provided by the body control module (BCM). When an ignition key is inserted into the ignition lock cylinder and the ignition is switched ON, the BCM supplies battery voltage to the theft deterrent exciter module. The transponder embedded in the head of the key is energized by the theft deterrent exciter module which is surrounding the ignition lock cylinder. The energized transponder transmits a signal that contains its unique value, which is received by the theft deterrent exciter module. The BCM monitors the theft deterrent exciter module for the transponder value. The BCM then compares this value to a value stored in memory, the learned key code. If the value is correct, the BCM sends the fuel enable password via serial data to the engine control module/powertrain control module (ECM/PCM). If the transponders value is incorrect the BCM will send the fuel disable password to the ECM/PCM via the serial data circuit. The components of the immobilizer system are as follows:
• BCM
• Theft deterrent exciter module
• ECM/PCM
• Ignition key (Transponder)
• Security indicator
Power Mode Description and Operation
Power to many of this vehicle's circuits are controlled by the module that is designated the Power Mode Master (PMM). This vehicle's PMM is the Body Control Module (BCM). The PMM controls which power mode (Run, Accessory, Crank, Retained Accessory Power, or Off) is active.
Serial Data Power Mode
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle, the PMM is the body control module (BCM). The PMM receives 3 discrete ignition switch signals to differentiate which power mode will be sent over the Serial Data circuits. The table below illustrates the state of these inputs in correspondence to the ignition switch position:
Relay Controlled Power Mode
The body control module (BCM) uses the discrete ignition switch inputs ignition 1, ignition 3 and crank to distinguish the correct power mode. Once the BCM has determined the power mode selected by the vehicle operator it will energize the Ignition relay, Run relay and retained accessory power (RAP) relay, depending on which power mode is selected.
Ignition 1 Relay
The relay uses a Hot At All Times B+ power source derived from the underhood electrical center. The ignition 1 relay supplies a power signal to the following circuits when the Run or Crank power mode is selected:
• AC clutch relay
• ABS STG angle sensor
• Antilock brake system (ABS) yaw sensor
• Auxiliary power drop connector
• Crank relay
• Cruse control switch
• Electronic brake control module (EBCM)
• Engine control module (ECM)
• HVAC module
• Ignition control module (ICM)
• Instrument panel cluster (IPC)
• Sensing and diagnostic module (SDM)
• Transmission solenoid circuit
Fail-Safe Operation
Since the operation of the vehicle systems depends on the power mode, there is a fail-safe plan in place should the power mode master (PMM) fail to send a power mode message. The fail-safe plan covers those modules using exclusively serial data control of power mode as well as those modules with discrete ignition signal inputs.
Serial Data Messages
The modules that depend exclusively on serial data messages for power modes stay in the state dictated by the last valid PMM message until they can check for the engine run flag status on the serial data circuits. If the PMM fails, the modules monitor the serial data circuit for the engine run flag serial data. If the engine run flag serial data is True, indicating that the engine is running, the modules fail-safe to RUN. In this state the modules and their subsystems can support all operator requirements. If the engine run flag serial data is False, indicating that the engine is not running, the modules fail-safe to OFF-AWAKE. In this state the modules are constantly checking for a change status message on the serial data circuits and can respond to both local inputs and serial data inputs from other modules on the vehicle.
Discrete Ignition Signals
Those modules that have discrete ignition signal inputs also remain in the state dictated by the last valid PMM message received on the serial data circuits. They then check the state of their discrete ignition input to determine the current valid state. If the discrete ignition input is active, battery positive voltage, the modules will fail-safe to the RUN power mode. If the discrete ignition input is not active, open or 0 volts, the modules will fail-safe to OFF-AWAKE. In this state the modules are constantly checking for a change status message on the serial data circuits and can respond to both local inputs and serial data inputs from other modules on the vehicle.
WE do not have a clue as to the shape of your vehicle , was it well maintained or is it a POS ? Checking for DTC'S - diagnostic trouble codes in all the modules on the vehicle , no cheap code reader will do this .
do you know what wiring diagrams are ? service repair information ?
Turn Signal Lamps
Ground is applied at all times at G200 to the turn signal/multifunction switch. The turn signal lamps may only be activated with the ignition switch in the ON or START position. When the turn signal/multifunction switch is placed in either the TURN RIGHT or TURN LEFT position, ground is applied to the body control module (BCM) through either the right turn or left turn signal switch circuit. Battery voltage is applied at all times to the BCM. The BCM then applies a pulsating voltage to the front and rear turn signal lamps. Ground for the left front turn signal lamp is supplied at G101. Ground for the right front turn signal lamp is supplied at G102. The left rear turn signal lamps are supplied ground at G402 and the right rear turn signal is grounded at G401.
Hazard Flasher Lamps
The hazard flashers may be activated in any power mode. The hazard switch is located on the radio/HVAC control panel and is permanently grounded through G402. When the hazard switch is placed in the ON position, ground is applied through the hazard switch signal circuit to the body control module (BCM). The BCM supplies battery voltage to all four turn signal lamps in an ON and OFF duty cycle. When the hazard switch is activated, the BCM sends a serial data message to the instrument panel cluster (IPC) requesting both turn signal indicators to be cycled ON and OFF.
There is no flasher fuse . Main power fuse's for the BCM - if one of these were blown you would have more then just the flashers not working .
Your best bet , take it to a qualified repair shop.
STARTING DISABLED REMOVE KEY
Refer to Theft Systems Description and Operation in Theft Deterrent
STARTING DISABLED REMOVE KEY
The radio illuminates the STARTING DISABLED REMOVE KEY message when the VTD system has disabled the starting system. The radio receives a message from the theft deterrent control module via the serial data circuit requesting illumination.
Your best bet have it towed to a qualified repair shop .
The vehicle theft deterrent (VTD) system functions are provided by the theft deterrent control module. When an ignition key is inserted into the ignition lock cylinder and the ignition is switched ON, the transponder embedded in the head of the key is energized by the exciter coils surrounding the ignition lock cylinder. The energized transponder transmits a signal that contains its unique value, which is received by the theft deterrent control module. The theft deterrent control module then compares this value to a value stored in memory, learned key code. If the value is correct the theft deterrent control module sends a random generated number to the transponder, this is called a challenge. Both the transponder and the theft deterrent control module perform a calculation on the challenge, if the calculations match the theft deterrent control module sends the fuel continue password via the serial data circuit to the Engine control module (ECM). If either the transponders unique value or the calculation to the challenge is incorrect the theft deterrent control module will send the fuel disable password to the ECM via the serial data circuit. The components of the VTD system are as follows:
• Theft deterrent control module
• Engine control module (ECM)
• Ignition key (Transponder)
• Ignition lock cylinder
• Security indicator
Is there a security light lit on the instrument cluster ? could be a anti-theft system problem ! Three electronic control modules involved in the starting circuit of this vehicle , BCM - body control module , PCM -powertrain control module , an theft deterrent module !
The immobilizer system functions are provided by the theft deterrent module (TDM) and the engine control module (ECM). When an ignition key is inserted into the ignition lock cylinder and the ignition is switched ON, the transponder embedded in the head of the key is energized by the exciter coil surrounding the ignition lock cylinder. This exciter coil is part of the TDM. The energized transponder transmits a signal that contains its unique value, which is received by the TDM. The TDM then compares this value to a value stored in memory. If the values match, the TDM will send the prerelease password via the serial data circuit to the ECM. If the transponders unique value is incorrect, the TDM will send the fuel disable password to the ECM.
When the ignition switch is placed in the Start position a discrete signal is supplied to the body control module (BCM) notifying it that the ignition is in the Start position. The BCM then sends a message to the engine control module (ECM) notifying it that CRANK has been requested. The ECM verifies that the transmission is in Park or Neutral. If it is, the ECM then supplies 12 volts to the control circuit of the starter relay. When this occurs battery positive voltage is supplied through the switch side of the starter relay to the starter solenoid.
If you knew how , in the under hood fuse / relay box is the
starter relay , it has a four pin socket when relay is removed ! Two should have battery voltage , one should show ground an one is control voltage from the PCM on pin 86 , pin 85 goes to ground. Pin . Pin 87 should have battery voltage an pin 30 supply's voltage to Fuse #24 marked STRTR in the under hood fuse / relay box ! Yea , if you look on the bottom or side of the relay the pins are marked ! Check for what is missing power or control an go from there .
If none of the windows work look for no power or ground or bad switch or control module. If only one or two don't work then check for bad switches or motors.
