Turn signal - multifunction switch

[snout_alert]

So the turn signals just stopped working the other day. 2 new (well, junk yard) multifunction switches later - same result. All other functions on the switch work fine. Bulbs are all checked and hazards/brake lights work fine. But no turn signals. Nothing. The next thing to check would seem to be the electrical circuits? However I have no information on what goes where. Is it possible that it's the wires going to the MFS as opposed to the MFS itself?

Also if anyone needs an MFS for a 91 Explorer I have one available

Welcome to this forum! Did you check the flasher?

Flashers?

Do you mean the hazards? They work just fine, which leads me to believe that the bulbs and power to those lights are ok.

You should hear a clicking sound when you turn on the turn signal just like the hazard flasher. Do you have a wiring diagram of these circuits? Check Autozone's website for a schematic.

No, that's the thing, no clicking, no nothing. I do have a wiring diagram from Autozone courtesy of another post on this site.

Could you post that diagram?

I could have sworn the explorer had two flashers.. One for the turn signals and one for the hazards... If that really is true (I'm pretty sure) then you could loose the flasher for turn signals and still have hazards.

A few years ago I had the same problem....the flasher and hazard was remain ever switch on and the solution was change the flasher, located in the fussible box...that was all !!......all correct now !!

i have a 94 x and it has two flashers...my signals weren't working either but my hazards were...so i took the hazard flasher out and put it where the turn signal one is and the turn signals work fine..i just did it a couple of weeks ago

The 91 has a big circular fuse that handles the turn signal AND hazard flashers. As the hazards are working (and the hazard flashers) I'm guessing this fuse is OK. The fuse for the turn signals themselves also looks fine and I've switched it out.... but will do it again. This is so frustrating as I don't want to have to spend $$$ to take this car and get it fixed as I bought it for nearly nothing! I do need the indicators to work though, Atlanta traffic is crazy and people need all the notice I can give them that I'm lumbering over into a different lane.
Any other suggestions? I appreciate all the help I've got so far.

According to this diagram the hazards use a different flasher than the turn signal.

However, normally when a flasher goes the lights just stay on instead of flash. From what I understand your not getting any lights when you turn on the signal.

I'd starting following the wires backwards.. Check the Light Blue wire going into the multi function switch. My guess is that you don't have power there which means no power to the multi function switch. The Purple/Orange wire by the fues box is the power to the turn signal flasher. If that doesn't have power Check the fuse box again (maybe a contact is bad if the fuse is good)
