Instrument panel and interior lighting not operating, 2004 F150

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

Principles of Operation
Vehicles equipped with remote keyless entry (RKE) have an illuminated entry feature, which enables the instrument cluster to illuminate the interior lamps (and if equipped, the puddle lamps in the exterior mirrors) when an unlock signal is received from the vehicle security module through the UBP network, or when any of the doors are opened. The instrument cluster controls the interior lamps illuminated entry feature by activating the battery saver relay. When active, the illuminated entry feature will be canceled when any of the following conditions are met:

• 25 seconds have elapsed since the illuminated entry feature was activated and the interior lamp control is not activated (door ajar or dimmer control switch ON).
• On vehicles equipped with RKE, the instrument cluster received a request from the vehicle security module (remote transmitter lock button pressed) and the interior lamp control is not activated.
• The ignition is in the RUN or START position and the interior lamp control is not activated.

For vehicles equipped with RKE, the instrument cluster illuminates the interior lamps when any door is open. The interior lamps shut off when the doors are closed and the illuminated entry feature is not active or when the vehicle speed is greater than 15 km/h (6 mph). The interior lamps are not reactivated until the vehicle speed is less than 15 km/h (6 mph) and a new door open signal is received.
For vehicles without RKE, the instrument cluster illuminates the interior lamps and puddle lamps (if equipped) when any door is open. The instrument cluster will turn the interior lamps and puddle lamps (if equipped) OFF when the doors are closed.
Power to the on-demand lamps, illuminated vanity mirrors and map lamps are controlled by the battery saver relay.

Interior Lighting The interior lamp system is separated into 2 subsystems: the interior lamp subsystem and the on-demand lamp subsystem. The dome light and front map light on-demand lamps are also part of the interior lamp subsystem.
An on-demand interior lamp will only illuminate when its specific switch is activated. On-demand lamps consist of the front map light and the dome light.
The instrument cluster illuminates the interior lamps when any door is ajar, when an unlock signal is received by the vehicle security module (if equipped with remote keyless entry (RKE) or the dimmer switch is rotated to the ON position. The instrument cluster will turn off the interior lamps when all doors are closed, the vehicle security module (if equipped with RKE) receives a lock signal, 25 seconds have elapsed since the illuminated entry feature was activated, or the dimmer switch is rotated to the OFF position.
The vehicle is also equipped with a battery saver feature. The battery saver feature provides automatic shutoff of the demand lamps, courtesy lamps, and the warning chimes after a specific period of time has elapsed in order to save battery power.

   • Go To Pinpoint Test A .
   Pinpoint Test A: The Interior Lamps Are Inoperative
   Normal Operation On vehicles equipped with remote keyless entry (RKE), the door ajar switches are hardwired to the vehicle security module. The vehicle security module monitors the status of all door ajar switches, and when a door is opened, transmits a dome lamp ON signal to the instrument cluster through UART based protocol (UBP) circuit 1906 (PK), indicating a door has been opened. When the instrument cluster receives the dome lamp ON signal from the vehicle security module, the instrument cluster energizes the interior lamp circuits, which illuminates the interior lamps and, if equipped, the puddle lamps in the exterior mirrors.
   On vehicles without RKE, the door ajar switches are hardwired to the instrument cluster. When the driver or passenger door is opened, the instrument cluster receives a ground signal from the driver door ajar switch through circuit 344 (BK/YE), or from the passenger door ajar switch through circuit 345 (BK/PK), and the instrument cluster energizes the interior lamp circuits, causing the interior lamps to illuminate.
   The dimmer control switch can be used to turn the interior lamps ON or OFF when the doors are closed. The interior lamp defeat switch can be used to turn the interior lamps OFF when the doors are open.

Principles of Operation
The instrument cluster illuminates the interior lamps when an unlock signal is received from the vehicle security module. The illuminated entry feature will be canceled when any of the following conditions are met:

• 25 seconds have elapsed since the illuminated entry feature was activated and the interior lamp control is not activated (door ajar or courtesy lamp switch on).
• The instrument cluster receives a request from the vehicle security module (remote transmitter lock button pressed) and the interior lamp control is not activated.
• The ignition is in the RUN or START position and the interior lamp control is not activated.

The instrument cluster illuminates the courtesy lamps when any door is open or ajar. The courtesy lamps shuts off when the doors are closed and the illuminated entry feature is not active or when the vehicle speed is greater than 5 mph (8 km/h). The interior lamps are not reactivated until the vehicle speed is less than 3 mph (5 km/h) and a new door open warning lamp signal is received.
The instrument cluster controls the courtesy lamps illuminated entry function by activating the battery saver relay.
The panel dimmer switch is integrated into the headlamp switch and controls the interior lamps by activating the instrument cluster through circuit 1034 (BK/WH).
The vehicle security module sends a signal to the instrument cluster on the UBP network circuit to indicate a request to turn the illuminated entry feature on or off.
The on-demand lamps, glove compartment assembly, homelink module, puddle lamps and illuminated vanity mirrors are controlled by the battery saver relay. The battery saver relay becomes active (relay coil is energized) when the instrument is in the awake mode, or in the sleep mode (relay coil is de-energized).

There is no relay for the instrument panel. The dash lights and interior lights have fuses. The instrument panel itself is illuminated by the Central Power Module.

Might want to start with checking your stop lamps & the fuse for the stop lamps.

The shift interlock is part of the stop lamp circuit on the 97-03 MY trucks, and without working stop lamps, the truck does not come out of park,

Not too sure what you mean by cab lights, is this the interior dome lamps or the instrumentation illumination ?

If the fuses are good there should be a dial that adjusts the brightness of the dash panel.If this dial doesn't work then the bulbs for the dash panel might be blown out.

First thing to check is the interior light / dome light control. It is usually located to the left of your instrument panel (where your odometer is located). It you move this dial up or down it will control the intensity of interior lighting.

However, if that does not cure the issue, it is possible that you have a short somewhere, or a bad bulb for the instrument panel. At that point, I'd take it to your local repair facility and have them check it out. Changing interior lighting or testing for electrical failures can be a difficult task.
