Check fuse and turn signal flasher relay.
2002 ford explorer turn signals not working
There are a couple of reasons why the turn signals will not work on a 1998 Ford Explorer. The light bulbs may need replaced or a fuse has blown.
If your 1999 Ford Expedition has turn signals that do not work but hazard lights that do work, it is likely that you have a fuse that is blown. You might also have a wiring issue including exposed wiring.
Check your fuse!
change the turn signal flasher flasher could be a fuse
If the 4 Ways/Hazards are disconnected then neither will work the park lights nor the turn signals.
Most commonly the flasher - usually located in or near the fuse box - perhaps at the left lower side of the dash by the steering column it just plugs in
Check ground on that fixture short in the wiring it sounds like
will a gear shifter fork plate on 89 ford f150 work on 96 ford f150
Is the bulb blown?
we have turn signals but no back up brake or warning signals we get power to signal switch on transmission but not beyond that point should this modual be changed keep in mind that this is a 1981 ford f150 and if this modual is changed will that help?
check the fuses.
