Signal issues (1 Viewer)

[Ouiser]

Hello,
Trying to figure out why I have no signals or hazards. I've checked the fuses, but all the manuals make it look like my fuse panel might not be original (see pic). I have wipers so I assumed that turn signals were good fuse wise as well but that isn't true for every year truck (my fuse cover says that's the case though). When I hit the hazard switch I hear a click so I think the flasher module is good (really hope I don't have to figure out how to pull that thing, doesn't look easy to get back there).

So now I think it might be the flasher unit. Anyone know where that is on a 78 (Dec 77)? Any other ideas of what it might be? I've done a search and will keep looking, but nothing so far.

Thanks!

This looks promising. I think I'll try a new flasher unit. I still don't know where it's located though if anyone could point me in the right direction.

Thanks.

Up and toward the firewall from your fuse block. It's mounted on the outboard side of the pedal mount.

The flasher unit sits behind the fuse block and it looks like this

It's a pain to remove. If you want a modern replacement check with @Coolerman he's our resident electrical wizard. Good luck!

Your pic didn't come through. Is it a silver box on the pedal mount? Ya, that's going to be a pain.

The pic works on my computer, I think it may need some time to load it all depends on your internet speed and computer RAM.

Your fuse box is correct for a '78 but it's not shown in the Toyota FSM and Haynes manuals.

Your picture might work on your computer but it doesn't show on our computers. You probably used an internal link.
You'll need to upload the picture from your computer to the forum or upload to a server and use a download link to post it here.

Thanks Rudi. I'll list the fuse order on my cover when I get home just to double check.

Check your grounds before you go any further. I had the same thing happen cleaned the adjoining areas and bingo.

Yup grounds seem to be the culprit on most issues. I had all kinds of electrical issues until I cleaned up my grounds.

Look at other posts the pros on here will tell you to make sure all your grounds are good. Clean off old paint/rust/corrosion. Have good clean metal to clean metal contact.

Your cover should look like this
