WARNING: This page is about a different car, the 2012 Ford Pickup. 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.

B1 CHECK THE VOLTAGE TO THE LH FRONT WINDOW CONTROL SWITCH
- Disconnect: LH Front Window Control Switch C504 (Regular Cab) or C535A (SuperCab or SuperCrew).
- Ignition ON.
- Measure the voltage between LH front window control switch and ground.
  - For regular cab, measure the voltage between C504-3, circuit CBP32 (GN/VT), harness side and ground.
  - For SuperCab or SuperCrew, measure the voltage between C535B-1, circuit CBP01 (BU), harness side and ground.

- Is the voltage greater than 10 volts?
  - Yes : INSTALL a new LH front window control switch. REFER to WINDOW CONTROL SWITCH - FRONT . TEST the system for normal operation.
  - No : VERIFY Body Control Module (BCM) fuse 32 (15A) (regular cab) or BCM circuit breaker 48 (30A) (SuperCab or SuperCrew) is OK. If OK, GO to PINPOINT TEST J to diagnose the accessory delay circuit. If not OK, REFER to the Wiring Diagrams information to identify the possible causes of the circuit short. REPAIR the circuit. TEST the system for normal operation.
