    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  E4.
    2. NO  : Go to  E3.
  3. E3 CHECK CIRCUITS 320 (RD/BK) AND 319 (YE/BK) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: Driver Window Control Switch C504a
    • Measure the resistance between driver window control switch C504a-3, circuit 320 (RD/BK) and passenger rear window control switch C801-3, circuit 320 (RD/BK), harness side.

    • Are the resistances less than 5 ohms? 
    1. YES  : INSTALL a new passenger rear window control switch. REFER to Window Control Switch - Rear  in this article. TEST the system for normal operation.
    2. NO  : REPAIR circuit 320 (RD/BK) or circuit 319 (YE/BK). TEST the system for normal operation.
  4. E4 CHECK THE PASSENGER REAR WINDOW CONTROL SWITCH 
    • Disconnect: Passenger Rear Window Control Switch C801
    • Key in ON position.
      NOTE: Set the driver window control switch to the UNLOCK position.
    • Connect a fused jumper wire between passenger rear window control switch C801-5, circuit 319 (YE/BK) and C801-2, circuit 882 (BN/YE); and a second fused jumper wire between C801-4, circuit 193 (YE/LG) and C801-6, circuit 881 (BN) harness side. The window should operate in the upward direction.

    • Does the window operate correctly? 
    1. YES  : If the passenger rear window did not operate with the passenger rear window control switch, INSTALL a new passenger rear window control switch. REFER to Window Control Switch - Rear  in this section. If the passenger rear power window did operate with the passenger rear window control switch but not with the driver front window control switch, INSTALL a new passenger front window control switch. REFER to Window Control Switch - Front  in this article. TEST the system for normal operation.
    2. NO  : Go to  E5.
  5. E5 CHECK CIRCUITS 882 (BN/YE) AND 881 (BN) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: Passenger Rear Window Motor C803
    • Measure the resistance between passenger rear window control switch C801-6, circuit 881 (BN) and passenger rear window motor C803-1, circuit 881 (BN) harness side.
