I am pretty sure that these are two separate issues but including them in the same post just in case.

1. All of the blinkers work except:
A) the left turn signal indicator on the dash
B) the left front
I checked the dash bulb and my son checked the left front bulb. Left rear works fine. Hazards don't activate either of those two bulbs either.

2. The horn/cruise buttons do nothing. I just wish I could find where they come out of the column so I could at least troubleshoot it. Horn works from the relay.

Any ideas are appreciated! Thank you!

 

It matters what year of truck you're talking about. So that you don't have to remember each time you ask a question, and so that we don't have to ask your or go back looking through your posts, put ALL its details into your signature as this caption explains:

Put EVERYTHING about the truck in your sig now so you don't have to keep adding to it each time you have a new question.

 

Something must be wrong. I tried adding it a few times (mobile) and it just won't save. Going to try it on PC..
Anyway 1993 f150 4x4 302

 

That's hardly "everything" about the truck. And we already assume it's an F150, so you can skip that. Re-read that caption above.

As you can see I found the issue (it is required to 'save' on each field) but I am not sure what else you want. Color? Type of floor mats? Jk. I went back and added cruise, a/c pw/pl

 

The signature thing is pc only so give basic truck info on each new thread for the phone users,you could add auto or manual.

I'll take a shot at the actual question. Horn and cruise might very well be a fuse. When you find the right one it might pay to just replace as they can look good but be bad.Flasher relay is in the under dash fuse block, I'd just throw a new one in. If a bulb is questionable install a new one.

Bulbs and fuses are the only parts where I will just throw a new one at it if there is any question if the old is good or not. For $20 you can replace almost every bulb and most fuses minus the headlights. Not worth trying to determine if a .05 cent 25 year old part is any good just install new of good quality.

 

Since I don't ever like leaving anything unresolved here is a summary of the problem and how I corrected it.

Problem: the left turn signal operating normally in the back of the truck but the turn signal lights on the dash did not eliminate and neither did the left front blinker.

Resolution: since there was no voltage going to the left front blinker or the dash turn signal I narrowed it down to the multifunction switch. As soon as I remove the old switch I inadvertently hit the flashers and to my surprise the light on the dash lit up and so did the left front blinker. I replace the multifunction switch anyhow and all is well now. It was either a weak connection to the switch itself or one of the wires in the loom.
