Pinpoint Test A: All Power Windows Are Inoperative

WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
  1. A1 CHECK THE VOLTAGE TO THE DRIVER WINDOW CONTROL SWITCH - CIRCUIT 400 (LB/BK) 
    • Disconnect: Driver Window Control Switch C535 (Regular Cab) or C504b (SuperCab or SuperCrew).
    • Key in ON position.
    • For Regular Cab, measure the voltage between driver window control switch C535-1, circuit 400 (LB/BK) harness side and ground.

    • Is the resistance less than 5 ohms? 
    • Yes  : INSTALL a new driver window control switch. Refer to WINDOW CONTROL SWITCH - FRONT . TEST the system for normal operation.
    • No  : REPAIR the circuit. TEST the system for normal operation.
  3. A3 CHECK THE ACCESSORY DELAY RELAY 
    • Key in OFF position.
    • Disconnect: Accessory Delay Relay.
    • Carry out the accessory delay relay component test. Refers to COMPONENT TESTING -- F150 PICKUP article .
    • Is the accessory delay relay OK? 
    • Yes  : GO to  A4.
    • No  : INSTALL a new accessory delay relay. TEST the system for normal operation.
  4. A4 CHECK THE POWER TO THE ACCESSORY DELAY RELAY 
    • Key in ON position.
    • Measure the voltage between accessory delay relay socket pin 85 and pin 30 harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes  : GO to  A5.
    • No  : REPAIR the power supply circuit or central junction box (CJB). TEST the system for normal operation.
  5. A5 CHECK CIRCUIT 400 (LB/BK) FOR AN OPEN 
    • Key in OFF position.
    • For Regular Cab vehicles, measure the resistance between driver window control switch C535-1, circuit 400 (LB/BK) and accessory delay relay socket pin 87, circuit 400 (LB/BK) harness side.
