Interior wiring in drivers door. Radio, mirror lights, dome light on console, trunk light, power door locks and electric mirror switches don't seem to work. I suspect a fuse, #4 20 amp. under the hood and possibly #5 10 amp. under the dash. But if I replace one or both and they blow out again, I would like to find a schematic for this problem. Can you tell me where I can see or get this schematic?

If the dome lights in your 2009 Cadillac CTS are not turning off, it can be a frustrating issue. Here are some steps to diagnose and potentially fix the problem:
1. **Manually Turn Off the Dome Lights:**
- In most vehicles, including the Cadillac CTS, there's typically a manual switch on or near the dome light itself. Ensure this switch is in the "Off" position.
2. **Check for Open Doors:**
- Make sure all doors, including the trunk and the hood, are completely closed. Sometimes, a door ajar can prevent the dome lights from turning off.
3. **Interior Light Dimmer Control:**
- Check the position of the interior light dimmer control, which is usually located on the headlight switch or dashboard. If it's turned all the way up, it may keep the dome lights on. Adjust it to the lowest setting.
4. **Ignition Switch:**
- Ensure the ignition switch is in the "Off" position. Sometimes, if the ignition switch is left in the "Accessory" position, the dome lights may stay on.
5. **Faulty Door Switches:**
- Each door usually has a door switch that signals the lights to turn on when a door is opened and off when it's closed. One of these switches may be malfunctioning. You can try manually pressing and releasing each door switch to see if the lights respond.
6. **Battery Disconnect and Reconnect:**
- If the above steps don't work, you can disconnect the vehicle's battery for a few minutes and then reconnect it. This can sometimes reset the electrical system and resolve the issue.
7. **Consult the Owner's Manual:**
- Refer to your Cadillac CTS owner's manual for specific information about the dome light controls and troubleshooting tips.
8. **Professional Diagnosis:**
- If the issue persists, it may be related to a more complex electrical problem. In this case, it's advisable to consult a professional mechanic or an auto-electrician to diagnose and repair the problem.
It's important to be patient and methodical when troubleshooting this issue, as it can have various causes. If you're not comfortable working on the electrical system of your vehicle, seeking professional help is a wise choice to avoid further complications.

Check fuses under the hood on driver side

Interior lights and the power door locks are controlled by a electronic control module . Hooking up a factory or some other type professional scan tool an checking for codes an viewing input data to these control modules would be the first thing to do.
The interior lighting system consists of the following:

• lighting control module (LCM)
• driver door module (DDM)
• instrument panel
• dome/map combination
• courtesy/reading lamps
• orientation light
• door lamps
• footwell lamps
• luggage compartment lamp
• glove compartment lamp
• vanity mirrors
• door ajar switches
• viewing wiring diagrams an checking power and ground circuits for these modules would be the next step if no codes were found . Principles of Operation
  Lighting Control Module This vehicle uses a lighting control module (LCM). The LCM is a microprocessor-based module that controls several vehicle subsystems, responds to electrical input signals from various switches, sensors, and external modules and is located on the LH side of the instrument panel. LCM subsystem functions include:
  
  • headlamps with autolamps
  • turn signal lamps/hazard flasher lamps
  • cornering lamps
  • parking lamps
  • daytime running lamps
  • interior lamps
  • demand lamps
  • battery saver
  The LCM interfaces with the driver door module (DDM) via the standard corporate protocol (SCP) network for the illuminated entry feature.
  The interior lamp is illuminated by pressing the individual interior lamp switch. The interior lamp is also illuminated by door ajar switches located in the door latches, when any door is opened. A theater lighting feature gradually increases or decreases the light intensity when switched by opening or closing a door.
  The dome/map lamp combination are located on each side of the interior lamp. The map lamps are operated independently of the interior lamp by two switches located on the interior lamps.
  The interior lamps are illuminated by holding the panel dim switch in the UP position until the dome lamps turn on. The interior lamp also illuminates when a door is opened and actuates the door ajar warning lamp switch in the door latch.
  The front map lamps are powered by the demand lighting circuit and the interior lighting circuit.
  The rear passenger reading lamps are incorporated into the rear seat assist handle and are located over the rear door openings. These lamps are illuminated through power supplied by the LCM demand lighting circuit.
  Interior lamps (controlled by the LCM) are activated by using the dome lamp switch (instant ON/OFF response) or when a door is ajar. The following lamps illuminate for interior lighting:
  
  • instrument panel interior lamps
  • front map lamps
  • rear reading lamps
  • door lamps
  Demand lighting includes lamps that are illuminated by the customer by directly actuating a switch. The front dome/map lamps are located in the overhead console. Each lamp is controlled by its own switch.
  The following demand lamps are powered by the demand lighting output of the LCM:
  
  • glove compartment lamp
  • vanity mirror lamp
  • luggage compartment lamp
  Each lamp has a dedicated switch that closes to ground to illuminate the lamp.
  The front map lamps are powered by either the demand lighting circuit or the interior lighting circuit, depending upon the position of the switch associated with each lamp. When the customer turns the front map lamp switch ON, the front map lamp is illuminated through power supplied by the LCM demand lighting circuit. If the customer moves the map lamp switch to the OFF position, the power from the LCM demand lighting circuit is interrupted and the lamp is reconnected to the interior lighting circuit.
  The rear reading lamps are powered by either the interior lighting circuit or the demand lighting circuit.
  The luggage compartment lamp is controlled by the trunk ajar switch, and is powered by the demand lighting output from the LCM, and is mounted near the center of the upper rear panel.
  The glove compartment lamp system consists of a glove compartment lamp switch and wire and miniature bulb assembly. Opening the glove compartment door closes the switch which provides power to the glove compartment lamp switch and wire. The glove compartment lamp switch is grounded to the body sheet metal.
  The vanity mirror lamp system consists of a switch and bulb assembly in the RH inside visor and the LH inside visor. Lifting the vanity mirror cover closes the vanity mirror lamp switch and provides power to the lamps.
  The illuminated entry system is controlled by the LCM and provides interior lighting upon entry to the vehicle.
  Interior lamps will be illuminated for 25 (±1) seconds which includes a theater lighting ramp-up time (0.5 seconds). This time interval does not include the theater lighting ramp-down time. Interior lamps will be turned off before the 25 (±1)-second timeout if the ignition switch is turned to the RUN or ACC position.
  The illuminated entry system has the following additions to accommodate the remote entry system: pressing the unlock button on the remote transmitter will activate the illuminated entry system (with theater ramp-up). When the driver door module detects a button press, it sends a signal on the J1850 communication network activating the interior lamps. The lighting control module will turn off the lamps by sensing the all doors lock signal.
  The battery saver feature prevents excessive drain from loads inadvertently left on. When the ignition switch is turned OFF, power is interrupted to the interior lamps and headlamps (after a 10-minute timeout) and the demand lamps (after a 30-minute timeout).
  The battery saver has the following inputs:
  
  • luggage compartment door ajar switch
  • dome lamp switch
  • ignition switch status
  • illuminated entry signal
  • headlamp switch
  • driver/passenger door ajar entry switch
  • keyless entry remote transmitter
  • door unlock, luggage compartment door release

trace wires to find the short

the chime actually is done with the radio. the front drivers door speaker. so if the radio works and the front left speaker works. then more then likely you have a defective door switch. located in the door jam that controls the dome light

it sounds like a broken wire in the passenger door.

Interior Lights Circuit Description
By using a feature called inadvertent power control, the body control module (BCM) supplies power to all of the following components:
• The courtesy lamps
• The dome lamps
• The rear view mirror reading lamps
• The instrument panel compartment lamp
• The rear compartment lamp
The left front door ajar switch turns the interior lamps on through the BCM by grounding CKT 394. When the left front door is open, the switch is closed. This condition provides a ground and a door open input to the BCM. The BCM then grounds the following lamps through CKT 156 in order to turn the lamps on:
• The courtesy lamps
• The dome lamp
• The rearview mirror lamps
The right front door ajar switch and the rear door ajar switches turn the interior lamps on by grounding CKT 395 from the BCM.
When the ignition key is removed from the lock cylinder, the interior lamps remain on for approximately 40 seconds.
The BCM provides an interior lamps-on delay after a door is opened. The lamps remain on for approximately 40 seconds or until the ignition switch is turned to the ON position. The 40 second lamps-on delay reduces to 4 seconds if a door is opened within 2 minutes of the ignition switch being moved from the ON position. The interior lamps immediately turn off when the vehicle begins to move.
The dome lamp OFF-DOOR-ON switch controls the dome lamp. When the switch is in the OFF position, the dome lamp remains off. When the switch is in the DOOR position, the dome lamp lights when a door is opened by the BCM grounding CKT 156. When the switch is in the ON position, ground is supplied through CKT 750. The rear view mirror reading lamps are controlled by the rear view mirror reading lamps switch or through CKT 156 from the BCM.
Voltage is supplied at all times to the BCM through the INT LPS fuse. The BCM supplies voltage to the interior lamps through CKT 1732.

Battery Run Down Protection
When the ignition switch is in the OFF position, the BCM turns off the power to all of the interior lamps after 18-22 minutes.
The BCM will reset the inadvertent power control relay output when one of the following actions is performed:
• Open or close a door.
• Turn the ignition switch to the ON position.
• Turn off any interior lamps that may be on.
• Press the power door lock switch/keyfob button.
• Press the decklid release keyfob button.
