    • Are the resistances less than 5 ohms? 
    1. YES  : Go to  A3.
    2. NO  : REPAIR the circuit(s). TEST the system for normal operation.
  3. A3 CHECK THE POWER SLIDING WINDOW SWITCH 
    • Key in ON position.
    • Connect a fused jumper between power sliding window switch C203-2, circuit 400 (LB/BK) and C203-1, circuit 405 (VT/LB) harness side; and between power sliding window switch C203-7, circuit 404 (VT/LG) and C203-6, circuit 57 (BK) harness side. The power sliding window should close.
