What is wrong with my tail light?

Asked by Mar 20, 2015 at 04:22 PM about the 2004 Ford F-150 XLT Ext. Cab LB

Question type: Maintenance & Repair

I have a 2004 f150. I am having a tail light
issue on the drivers side. All running lights
work. (Including drivers side) when I turn on
my hazards all lights work. My blinkers
work but it blinks really fast on the drivers
side. When my truck is in park and I press
the brake peddle both brakes work. But
when my truck is in drive the drivers side
brake light does not turn on. If my running
lights are on my drives side brake light will
turn off when the peddle is pushed. This
only happens when the truck is in drive, the
brake will turn on while in park. I have
replaced the bulb and I am still having the
same issue. What could the issue be?

The fast blinking light on one side indicates a burned out bulb normally. Sounds like you have a a short. You are going to need a multimeter to be begin checking voltages beginning at the brake pedal.
