Coming home from a delivery my turn signal just stopped working. My 4 ways still work. The light switch and multi function are less than 1 year old. I need to get them working quick. I have a load of hay goiong out first thing in the morning

 

Sounds like you have a light out.

Have somebody help you check ALL your lights.

The 4 ways I think will always work, but if you have a tail light out or a front blinker out they will malfunction. specially if its one of the main links in the chain.
I could never figure out why they wire lights in series.

 

Have you checked or changed the flasher yet? Both the turn signals and 4 ways have seperate ones, so if the signal flasher burns out the 4 ways will still work.

 

Yea, the relay could have went out as well.
or are you saying the little round dealio?

I believe there is a fuse for this also?

 

Yeah, the li'l round thingy in the bottom right corner of the in cab fuse panel is for the signals. And the #7 15 amp fuse protects that circuit.

 

checked all fuses and theyre ok. you can hear flasher click when 4 ways on.

 

4 ways and signals each have their own seperate flasher. The signal flasher is the one you see when you remove the access panel, the 4 way flasher is hidden on the back side of the fuse panel and you have to lay on the floor and look under the dash to see it. It's directly opposite the one for the blinkers and looks the same, that's the one you hear clicking. They're interchangable, so if you wanna swap them out you can verify that the signal flasher is bad.

 

Either a bad signal switch on the column or a pinched/worn wire
