Well I've gone through circuit board behind the dash and the seems to be in good shape. There is a bulb missing, could that cause some of this? I have not gotten into the turn signals or brake lights yet. I did go get a manual so I have the wiring diagrams. Also, I found the wring in the dash is a mess, lose connectors and cut wires everywhere. I've got to get all that sorted out and then see where things are.

 

I had a similar problem when I got my truck, hazards worked, turn signals didn't, easy fix right, went to Advance and bought a new relay switch, put it in and nothing.....long story short, try this set the turn signal lever to a blink position, and wait, if you get a faint blink every once in a while, the relay is too weak, as was my problem, lucky for me the hazard relay was a Ford part, part number D3AB-13350-AA, I changed it to the turn signal and it works just fine, and the hazard works on the cheaper relay

 

Thanks for your help guys, but this is no longer my problem. I sold the truck last

 

Before u start rippin n tearing - signal wires run thru the hazard switch - I wiggled my hazard switch (with the turn signal on) and found they work when I lightly press forward on the hazard switch. Bad contacts in there. Hope yours is easy to find as well. Took me a year of banging on the dash before I found the loose connection there.
