2011 Ford F-150 FX4 6 Cyl 3.50L

Body & Interior

Left turn signal and left brake light suddenly went out

The turn signal and brake light work on the right side including the outside mirror. The left side brake light and left turn signal don't work however the left turn signal on the outside mirror does work. Here checked all bulbs and fuzes, replaced and still nothing. Could it be a short in the wire or it burned somewhere along the distance between front and back or bad harness or am I missing something else to check before I jump a new wire. Thanks for some insite. I know it starts with a beer,

The hazard flasher switch is located in the center instrument panel finish panel (integrated into the FCIM (Front Controls Interface Module)). When the hazard function is active, all the turn lamps flash on and off.

The BCM (Body Control Module) sends a voltage signal to the FCIM (Front Controls Interface Module) to monitor for a hazard lamp function request. When the hazard flasher switch (a capacitive touch switch) is touched, the voltage signal is routed to ground, indicating a a request to activate or deactivate the hazard lamp function.

When the BCM (Body Control Module) receives a request for the hazard lamps, the BCM (Body Control Module) supplies on/off voltage to all the turn lamps.

The timed on/off cycle for the hazard lamps is approximately 80 times per minute regardless of bulb outage.
