- Is the voltage greater than 10 volts?
- Yes : INSTALL a new LH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
- No : VERIFY BCM fuse 32 (15A) (regular and SuperCab) or circuit breaker 48 (30A) (Crew Cab) is OK. If OK, GO to PINPOINT TEST F to diagnose the accessory delay circuit. If not OK, REFER to the SYSTEM WIRING DIAGRAMS to identify the possible causes of the circuit short. TEST the system for normal operation.
