    • Is the resistance less than 5 ohms? 
    • Yes  : INSTALL a new LH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
    • No  : REPAIR the circuit(s). TEST the system for normal operation.
  5. D5 CHECK THE RH FRONT WINDOW CONTROL SWITCH 
    • Ignition ON.
    • Connect a fused jumper wire between RH front window control switch C604-1, circuit CPW12 (GN/OG) and RH front window control switch C601-5, circuit CPW20 (WH/OG); and a second jumper wire between RH front window control switch C604-3, circuit CPW14 (VT/WH) and RH front window control switch C604-2, circuit CPW19 (VT), harness side. The RH front window should move in the downward direction.
