Pinpoint Test A: The Control Illumination Is Inoperative/Always On

WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
  1. A1 CHECK THE OPERATION OF THE CONTROL ILLUMINATION 
    • Key in ON position.
    • Make sure the headlamp switch is in the OFF position.
    • Is the control illumination on? 
    • Yes  : GO to A2.
    • No  : GO to  A4.
  2. A2 CHECK THE HEADLAMP SWITCH FOR AN INTERNAL SHORT TO POWER 
    • Key in OFF position.
    • Disconnect: Headlamp Switch C205.
    • Key in ON position.
    • Is the control illumination on? 
    • Yes  : GO to A3.
    • No  : INSTALL a new headlamp switch. REFER to EXTERIOR LIGHTING . TEST the system for normal operation.
  3. A3 CHECK CIRCUIT 1045 (DB/WH) FOR A SHORT TO VOLTAGE 
    • Remove central junction box (CJB) fuse 36 (5A).
    • Is the control illumination on? 
    • Yes  : REPAIR circuit 19 (LB/RD). TEST the system for normal operation.
    • No  : REPAIR the circuit 1045 (DB/WH). TEST the system for normal operation.
  4. A4 CHECK CIRCUIT 195 (TN/WH) FOR VOLTAGE 
    • Key in OFF position.
    • Disconnect: Headlamp Switch C205.
    • Measure the voltage between the headlamp switch C205 pin B2, circuit 195 (TN/WH), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes  : GO to A5.
    • No  : REPAIR the circuit. TEST the system for normal operation.
  5. A5 CHECK CIRCUIT 1045 (DB/WH) FOR AN OPEN 
    • Remove central junction box (CJB) fuse 36 (5A).
    • Measure the resistance between the headlamp switch C205 pin I, circuit 1045 (DB/WH), harness side and CJB fuse 36 (5A) input side.

    • Is the resistance less than 5 ohms? 
    • Yes  : GO to A6.
    • No  : REPAIR the circuit. TEST the system for normal operation.
  6. A6 CHECK CIRCUIT 19 (LB/RD) FOR AN OPEN 
    • Disconnect: Climate Control C294e.
    • Measure the resistance between the CJB fuse 36 (5A) output side, circuit 19 (LB/RD) and the front climate control assembly C294e pin 2, circuit 19 (LB/RD).
