  1. D1 CHECK THE LH FRONT POWER WINDOW MOTOR 
    • Disconnect: LH Front Window Control Switch C504A and C504B
    • Key in ON position.

    • Connect a fused jumper wire between LH front window control switch C504A-5, circuit CPW11 (BU/GY), harness side and LH front window control switch C504A-2, circuit CPW30 (GY/YE), harness side. Connect a second fused jumper wire between LH front window control switch C504A-1, circuit CPW10 (YE/VT) and LH front window control switch C504B-7, circuit GD126 (BK/WH). The LH front window should operate in the up direction.
      • Fig 2: Connecting Fused Jumper Wire Between LH Front Window Control Switch C504A-1 & C504A-2, CPW10 (YE/VT) & CPW30 (GY/YE)

    • Connect a fused jumper wire between LH front window control switch C504A-1, circuit CPW10 (YE/VT), harness side and LH front window control switch C504A-2, circuit CPW30 (GY/YE), harness side. Connect a second fused jumper wire between LH front window control switch C504A-5, circuit CPW11 (BU/GY) and LH front window control switch C504B-7, circuit GD126 (BK/WH). The LH front window should operate in the down direction.
    • Does the LH front window operate correctly? 
    1. YES  : INSTALL a new LH front window control switch. REFER to Window Control Switch . TEST the system for normal operation.
    2. NO  : Go to  D2.

    • Measure the resistance between LH front window motor C518-1, circuit CPW11 (BU/GY), harness side and LH front window control switch C504A-5, circuit CPW11 (BU/GY), harness side; and between LH front window motor C518-2, circuit CPW10 (YE/VT), harness side and LH front window control switch C504A-1, circuit CPW10 (YE/VT), harness side.
    • Are the resistances less than 5 ohms for both measurements? 
    1. YES  : INSTALL a new LH front window motor. REFER to Glass, Frames and Mechanisms - Exploded View, Front Door  and Window Regulator and Motor - Front Door . TEST the system for normal operation.
