The blinkers on are ford don't work we tried to but in fuses but all the fuses work

Fuse 13 and 28 in the instrument panel fuse block.

Suspect the multi-function switch. (turnsignal) these fail a lot.

make sure your fuses are ok and youve got power if ok check the blinker sender unit its usually round and silver with 2 or 3 wire going to it. usually under the dash but could be in the engine bay

There should be a flasher unit on the fuse box under the dash for the turn signals and another behind the dimmer switch for the hazards.
Sometimes one of the flashers is behind the fuse box in the glove compartment if equipped.
Don't be surprised if the flasher is not the problem. Most of the time the problem is the multi-function switch on the column.
There are stories online about using WD40 to take care of the switch problem.

That should be on two different fuses, but everything goes thru the turn signal switch.
The switch might be faulty. A mechanic would check for voltage there.

blinkers sounds like the flasher unit is not working. It's located under dash. Also check for burnt out bulbs.
Rear defrost, or rear defogger?: Your defogger for the rear window would run off a relay, probably located in the fuse panel of your car. Often, the connections at the rear window get broke or disconnected.
Front defrost: does your heater blower work?

About your 1994 Ford Explorer 4.0L MFI 6cyl. the Flasher is located: Front seating area, driver side, driver side of steering column, behind access panel, mounted on fuse panel (for Turn signal).

Hope this helps.

Look under the dash for a panel of fuses open the lid and look inside the lid for a list of them and see which one goes to the blinkers, dimmer, or head lights check them all by pulling them out and looking thru them to see if the wire in them is broke if so replace it if not you may have another set under the hood try those as well you may have a relay switch in the fuse area as well looks like a little black square that may go to them that is bad as well if the fuses don't work you may need to get someone to check the relays

check your left side bulbs probably one that has a dual filament in the rear of your car

Assuming your battery is charged, ignition is on and the bulbs are all good

This sounds like a FUSE.

Be sure to check under the dash on both sides, drivers and passenger side.
Also under hood for any MAXI fuses...

Hope this helps you out.

Good Luck and Happy Motoring
