Check the bulbs
Check the flasher
Check the fuse...From the Owners Manuals:1995-1998 - Fuse #27 - Interior fusebox1999-2003 - Fuse #27 - Interior fusebox
You have a bad relay. Your blinkers run on a different relay than you hazards do.
More than likely a bad flasher relay for the turn signals. The hazard lights use a different flasher relay.
simply depress the hazard light switch on top of the steering column. if the switch does not turn on hazard lights the switch may need to be replaced. this is common with this body platform. Be aware that the turn signal and hazard switch are all one part. it is not a difficult task to change, but remember that you will need some expertise for dealing with the air bags and steering wheel removal
After replacing the burned out turn signal bulb, turn on the hazard flasher and then turn off the hazard flasher. This will reset the flashing on the turn signal from super fast to standard flashing.
Most likely a bad turn signal flasher
There are 2 separate flashers.jd
have you check the tail light fuse to see if it is blown. other possiblly is the headlight switch.
The hazard button alone can't be replaced. You will need to replace the complete signal switch which is called a multifunction switch.
Turn signal flasher Try in or near the fuse box
I should be able to answer your question if you say which YEAR of Ford Windstar ( I was looking at the 1996 Ford Windstar owners manual and it doesn't have any warning lights above the engine temperature gauge )
try the hazard warning light switch as if this fails the indicators will not operate then if not try the hazard light relay
