On my 1994 F-150 the turn signals just stopped working the otherday, so I replaced the flasher at the fuse panel, that did not work, then I tried replacing the whole turn signal unit, and that did not help either...The Emergency flasher do work, wipers, but not the turn signals...Can any one help me out as too what to check for, or what too do...Thanks

 

Check all your bulbs for good grounds. Sometimes. only 1 bulb can have a ground issue and they won't work properly. Sometimes, even though it has a bad ground a bulb will randomly work or will flash dull. Corrosion in the bulb sockets could cause an issue too. Also bad bulbs or even LED bulbs without load equalizers can cause this issue

 

Well all of my lights seem to work just fine, even the hazards do...The brake lights etc., so are you telling me to take out each one and look at them to see if there is any Corrosion...None of them are dim...???

I wish that I could find a schematic of the wiring on the turn signals, that way I might be able to trace it out, might you know where I can get it off of the Internet...???

Thanks for the reply

 

I myself don't know where to get a diagram, but I know a few people on here have posted them before. The main thing to check is grounds. If your brake lights work fine, your problem might be in the front lights. I had a Nissan that did something similar and it got so bad that when I turned on the hazards, the front turn signals alternated. And also, I know you said you changed the flasher, are you sure it was a good one? I could be faulty

 

Ok well I suppose that I will have to go and check out too see if they are all grounded...Yes I changed out the flasher relay, got it at the parts store, plugged it in, it did not work, so I took it right back in...Other than that I really am at a loss...But thanks for your time...

 

Go to autozone.com and register with the repair serction (free) and you should get a wiring diagram.

 

There are two flashers. One you can see from the front the other is pluged in on the oposite side of the other.

 

The one on the front of the fuse panel is for turn signals, the one on the back side is for emergency flashers..


I may have missed it, but I didn't see where you had checked the fuse for the turn signals......

 

Thanks I did register, yet I could not find anything that would show me the wiring diagrams...???

 

Should be some wiring diagrams there. Maybe not looking in right catagory.

 

Thanks for the reply, but I could not find anything on the turn signal wiring...Saw other diagrams but not that one, for which I need...Thanks for the reply
