Sounds like grounding issues, check the wiring at the headlamp switch as well as the turn signal switch. This guide can help us fix it

I have replaced the multifunction switch and check all fuses and still have nothing. I have checked all bulbs they are good Still no turn signal nor flashers. What else can it be and where is it located please need your help.

Check for voltage at the fuses in diagram. One fuse circuit is hot all the time, for hazard lamps. The other fuse goes hot with key on, for turn signals. Use a testlite to check voltage. Your flasher could be faulty?

Next, I'd have to check voltage circuits to and from multifunction switch.

Check to see if you have good ground at the tailights. It also may be a bad flasher

I have checked all of my fuses they are fine. All of the lights work with the acception of the turn signals, brake lights and hazzards. Whats wrong? The lights all worked when I got the truck on 7-1-13, then they stopped working. I have head lights and tail lights. But the brake, turn signals and hazzards don't work.

I had the same problem with my 86 F150. The problem was a bad ground at the tailights. Check to make sure you have a good ground.

I have a 97 ford f150, the other day my turn signals stop working flashers still worked just turn signals stopped. I opened the steering column and found two burnt wires on the turn signal harness, fuses were fine under the dash. I then replaced the harness and replaced multifunction control. While working under the dash turn signals worked for a short period then stopped. I then replaced both relay switches under the dash one blue one black still no turn signals fuses were still fine, I am lost any other relays or switches I don"t no about. HELP.

Well I started checking wires and refitted my switch and the turn signals came on, moved the column they when't off the switch on top pulls out slightly I will try something to make it snug the clip on top is broke. And as far as the wires go I did not check the ones on top just the side. The wires connecting to the turn are light blue with orange stripe (no power)fuse 1 fine, Dark blue with orange stripe (with power)

No problem on the time, so you've discovered the issue(connection) with the turn signals? I hope that the wiring diagram helped, I didnt understand the last part of your message, did you have another issue with the wires?

Hi:
It sounds like there may be a problem with the ignition switch. Does the engine crank when you try to start it? If so, are you getting spark and fuel?
