Pinpoint Test B: All Power Windows Are Inoperative - Fusion

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.

B1 CHECK FOR VOLTAGE TO MASTER WINDOW CONTROL SWITCH
- Disconnect: Master Window Control Switch C535A (if RH front window is equipped with one-touch up/down) or C537A (if RH front window is not equipped with one-touch up/down).
- Ignition ON.
- Measure the voltage between master window control switch C535A-3 or C537A-2, circuit CBP47 (GN/BU), harness side and ground.

- Is the voltage greater than 10 volts?
  - Yes: For vehicles not equipped with RH front window one-touch up/down feature, GO to B2.
    For vehicles equipped with RH front window one-touch up/down feature, INSTALL a new master window control switch. REFER to Window Control Switch . TEST the system for normal operation.
  - No: VERIFY SJB circuit breaker 47 (30A) is OK. If OK, GO to Pinpoint Test O to diagnose the accessory delay relay circuit.
    If not OK, REFER to the Wiring Diagrams information to identify the possible causes of the circuit short. TEST the system for normal operation.
B2 CHECK THE MASTER WINDOW CONTROL SWITCH GROUND CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: Master Window Control Switch C537B.
- Measure the resistance between master window control switch C537B-7, circuit GD126 (BK/WH), harness side and ground.

- Is the resistance less than 5 ohms?
  - Yes: INSTALL a new master window control switch. REFER to Window Control Switch . TEST the system for normal operation.
  - No: REPAIR the circuit. TEST the system for normal operation.
