blinkers and hazzards are not working

hey guys went out to Barstow to test out the new lower arms and springs and when I got back on the highway I noticed my blinkers and hazards were not working. I checked the fuses and they are fine. light bulbs are working. is there a relay or set of wires I should be looking at. btw dash is taken out of truck so everything is easy access.

thanks I just checked that thread out my fuses on 21 and 10 were fine. could it be a blinker mod gone wrong? I'll have to check it out this weekend when I have some day light.

just wondering if anyone has a wire diagram and could tell me what wires I can test so I can try and pin point the problem. the lights themselves work all corner lights are on, just dont have function of blinkers or hazards.

If they are dead front and rear, I would look for something in common to both like the flasher unit or the Multifunction stalk switch.

The flasher is usually yellow and the Multifunction Switch is the stalk on the left of the column that controls turn signals, hi-lo beam, wiper/washer. Before looking at any specific parts, I'd give it an inspection first to see if some connector in that area came apart or some wiring got damaged.

Sounds like the flasher took a crap. They're like 8 bucks. If its not the problem, then you have a spare.

ok im gonna buy a new flasher tonight and report back to you with my findings I really hope its the porblem. I removed my flasher and put a standard relay in and it still didnt work but I guess the flasher is not just a standard relay.

No the flasher has a bimetal spring inside that releases from the contact when it gets too hot, it cools off in about the same amount of time and then flips back to make contact again. The spring flicking back and forth is what makes the click-tick click-tick sound when the turn signals or hazards are on.
A normal relay has a 2 sides to it, a switch side and a solenoid side. When the solenoid side receives power it pulls the switch side, closed which completes the circuit for whatever it powers. The big difference is that the normal relay will stay on or off for as long as it receives power. Where-as the flasher will not.
