    • Measure the voltage between RH front window control switch C624-3, circuit 170 (RD/LB) harness side and ground.
    • Is the voltage greater than 10 volts? 
    1. YES  : Go to  C2.
    2. NO  : REPAIR the circuit. TEST system for normal operation.
  2. C2 CHECK CIRCUITS 313 (WH/YE) AND 314 (TN/LB) FOR GROUND 
    • Disconnect: RH Front Window Control Switch C624
      • Fig 2: Checking Circuit For Ground
      GF0032703Courtesy of FORD MOTOR CO.
    • Measure the resistance between RH front window control switch C624-1, circuit 314 (TN/LB), harness side and ground; and between RH front window control switch C624-6, circuit 313 (WH/YE), harness side and ground.
    • Are the resistances less than 5 ohms? 
    1. YES  : Go to  C4.
    2. NO  : Go to  C3.
  3. C3 CHECK CIRCUITS 313 (WH/YE) AND 314 (TN/LB) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: LH Front Window Control Switch C508a
      • Fig 3: Checking Circuit For Open
      GF0032704Courtesy of FORD MOTOR CO.
    • Measure the resistance between LH front window control switch C508a-3, circuit 313 (WH/YE) and RH front window control switch C624-6, circuit 313 (WH/YE) harness side; and between LH front window control switch C508a-2, circuit 314 (TN/LB) and RH front window control switch C624-1, circuit 314 (TN/LB) harness side.
    • Are the resistances less than 5 ohms? 
    1. YES  : INSTALL a new LH front window control switch. REFER to Window Control Switch . TEST the system for normal operation.
    2. NO  : REPAIR the circuit. TEST system for normal operation.
  4. C4 CHECK THE RH FRONT WINDOW CONTROL SWITCH 
    • Key in ON position.
      NOTE: Set the LH front window control lockout switch to the unlock position.
      • Fig 4: Connecting Fused Jumper Wire

    • Connect a fused jumper wire between RH front window control switch C624-1, circuit 314 (TN/LB) and RH front window control switch C624-5, circuit 1506 (RD/WH) harness side and a second jumper wire between RH front window control switch C624-3, circuit 170 (RD/LB) and RH front window control switch C624-2, circuit 1505 (YE/RD). The window should operate downward.
      • Fig 5: Connecting Fused Jumper Wire
      GF0032706Courtesy of FORD MOTOR CO.
    • Connect a fused jumper wire between RH front window control switch C624-1, circuit 314 (TN/LB) and RH front window control switch C624-2, circuit 1505 (YE/RD) and a second jumper wire between RH front window control switch C624-3, circuit 170 (RD/LB) and RH front window control switch C624-5, circuit 1506 (RD/WH) harness side. The window should operate downward.
    • Does the window operate correctly? 
    1. YES  : If the RH front window did not operate with the RH front window control switch, INSTALL a new RH front window control switch. If the RH front power window did operate with the RH front window control switch but not with the LH front window control switch, INSTALL a new LH front window control switch. REFER to Window Control Switch . TEST the system for normal operation.
    2. NO  : Go to  C5.
  5. C5 CHECK CIRCUITS 1505 (YE/RD) AND 1506 (RD/WH) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: RH Front Window Motor C623
      • Fig 6: Checking Circuit For Open
      GF0032707Courtesy of FORD MOTOR CO.
    • Measure the resistance between RH front window control switch C624-2, circuit 1505 (YE/RD) and RH front window motor C623-2, circuit 1505 (YE/RD) harness side.
      • Fig 7: Checking Circuit For Open
      GF0032708Courtesy of FORD MOTOR CO.
    • Measure the resistance between RH front window control switch C624-5, circuit 1506 (RD/WH) and RH front window motor C623-1, circuit 1506 (RD/WH) harness side.
    • Are the resistances less than 5 ohms? 
    1. YES  : INSTALL a new passenger front window motor. REFER to Glass, Frames and Mechanisms - Exploded View  and Window Regulator - Front Door . TEST the system for normal operation.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
