hazards can- be natural or human caused
need to see what fuses operate what in a 2004 ford 150 econoline.
did you check your fuses
The problem could result from either the hazard module, located below the fuse box by your foot, gone bad or the indicator control on the steering column is bad.
Read your owners manual
Check your fuses if it is not your fuses i would say check your hazard switch, mine went bad on my Nissan and caused that problem
A simple first step would be to check the fuses to these lights, then go from there.
Often, a separate flasher unit is used to activate the hazard flashers. This unit might be bad, or the switch to activate the hazard flashers might be bad. answer always there are 2 flashers.one for turn signals other for hazard replace hazard flasher They have separate fuses also.
it might be the hazard switch all the blinker circuit runs through it.
Check the fuses and it may be the flasher relay as they have 2 try turning the hazard lights on and off a few time as you relay may be stuck.
it is the relay, change it, it is the hazard button, the one with the red triangle.
the turn signal flasher may be the problem moast vehickles have one forturn &one for 4way
Check the fuses first.
