Fuse location for interior lighting 2007 f150 fxt4x4 also is there 2 dash lights it doesn't seem to be as bright as it used to


dash lights it doesn't seem to be as bright as it used to ???? Dimmer switch on full bright ? Visual Inspection Chart Electrical
  • Bulbs
  • Central junction box (CJB) fuse 24 (15A)
  • Circuitry
  • Vehicle security module (if equipped with RKE)
  • Instrument cluster
  • Door ajar switches

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.

  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  1. If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
    • check that the program card is correctly installed.
    • check the connections to the vehicle.
    • check the ignition switch position.
  1. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
  1. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
    • CAN, ISO or UBP circuits fault; all electronic control units no response/not equipped, refer to Section 418-00 .
    • No response/not equipped for instrument cluster, refer to Section 413-01 .
    • No response/not equipped for vehicle security module, refer to Section 419-10 .
    • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the instrument cluster.
    • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the vehicle security module.
  1. If the DTCs retrieved are related to the concern, go to the Instrument Cluster Diagnostic Trouble Code (DTC) Index or the Vehicle Security Module Diagnostic Trouble Code (DTC) Index.
  1. If no DTCs related to the concern are retrieved, GO to Symptom Chart .
  2. Symptom Chart Condition Possible Sources Action
    • The interior lamps are inoperative
    • Fuse
    • Circuitry
    • Instrument cluster
    • Dimmer control switch
    • 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.
      Possible Causes
    • Fuse
    • Circuit 53 (BK/LB) open or short to ground
    • Circuit 57 (BK) open
    • Circuit 402 (OG/LG) open
    • Circuit 1405 (LB/BK) short to ground

I have an 06 ford explorer the instrument cluster lights and radio lights don't work


Are these the lights you are talking about ?
Instrument Cluster and Panel Illumination The instrument cluster and panel illumination is used to provide backlighting to the instrument panel, switches, and control components when the headlamp switch is in either the PARKING LAMPS ON or HEADLAMPS ON position. The level of intensity is adjustable by rotating the instrument panel dimmer switch either up to increase intensity or down to decrease intensity.
Fixed Backlighting When the accessory delay relay is energized, switched voltage is supplied to the non-dimmable components and switches.
Dimmable Backlighting When the parking lamps or the headlamps are in the ON position the smart junction box (SJB) monitors the input from the instrument panel dimmer switch. The SJB sends a pulse-width modulated (PWM) voltage to the dimmable components and switches based on input received from the instrument panel dimmer switch. The SJB also sends a message over the controller area network (CAN) to the audio unit, and the instrument cluster to indicate the backlighting intensity level.
If you don't know about PWM an smart junction box your better off taking your vehicle to a quailified repair shop ! You don't the diagnostic tools or technical information . May have DTC'S - diagnostic trouble codes stored in the SJB (computer ). Do you know where SJB is located ?

How do I replace dash light bulbs on a 2007 Ford Escape?


What lights are not working ? The instrument cluster illumination is inoperative or all the lights ,radio , heater control head, all the switches that would be back lighted.
  • The climate control panel illumination is inoperative , The passenger door lock control switch illumination is inoperative. Could need new dimmer switch , new instrument cluster. When installing a new instrument cluster, it is necessary to upload the module configuration to the scan tool. Following installation of the new instrument cluster, download the module configuration from the scan tool into the new instrument cluster. Refer to Section 418-01 .
