Pinpoint Test H: A Single Power Window Is Inoperative - MKZ, LH Or RH Rear

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. H1 CHECK THE VOLTAGE TO THE LH OR RH REAR WINDOW CONTROL SWITCH

    • Ignition ON.
      • NOTE: Set the master window control lockout switch to the UNLOCK position.
    • Measure the voltage between the inoperative rear window connector and ground:
      • for the RH rear window control switch, measure the voltage between RH rear window control switch C819-3, circuit CPW14 (VT/WH), harness side and ground.
      • for the LH rear window control switch, measure the voltage between C701-3, circuit CPW14 (VT/WH), harness side and ground.

    • Are the resistances less than 5 ohms? 
    • Yes  : Go to  H4.
    • No  : Go to  H3.
  3. H3 CHECK THE CIRCUITS TO THE INOPERATIVE REAR WINDOW CONTROL SWITCH FOR AN OPEN 
    • Ignition OFF.
    • Disconnect: LH Front Window Control Switch C535B.
    • For an inoperative LH rear power window, measure the resistance between master window control switch C535B-1, circuit CPW15 (YE) and LH rear window control switch C701-1, circuit CPW15 (YE), harness side; and between master window control switch C535B-2, circuit CPW16 (BU/OG) and LH rear window control switch C701-6, circuit CPW16 (BU/OG), harness side.

    • Are the resistances less than 5 ohms? 
    • Yes  : INSTALL a new master window control switch. Refer to WINDOW CONTROL SWITCH  in this service information. TEST the system for normal operation.
    • No  : REPAIR the circuit(s) for an open. TEST the system for normal operation.
  4. H4 CHECK THE INOPERATIVE WINDOW CONTROL SWITCH 
    • Connect: Master Window Control Switch C535B.
    • Ignition ON.
    • For an inoperative LH rear window, connect a fused jumper wire between LH rear window control switch C701-2, circuit CPW21 (BN), harness side and LH rear window control switch C701-3, circuit CPW14 (VT/WH), harness side; and between LH rear window control switch C701-5, circuit CPW22 (GN/VT), harness side and LH rear window control switch C701-6, circuit CPW16 (BU/OG), harness side. The LH rear window should operate in the downward direction.
    • For an inoperative RH rear window, connect a fused jumper wire between RH rear window control switch C819-2, circuit CPW23 (GY), harness side and RH rear window control switch C819-3, circuit CPW14 (VT/WH), harness side; and between RH rear window control switch C819-5, circuit CPW24 (WH/VT), harness side and RH rear window control switch C819-6, circuit CPW18 (GY/VT), harness side. The RH rear window should operate in the downward direction.
