Turn signals and breaklights don't work.

Hey guys,

Today I started my truck and my brake lights, turn signals, and hazards aren't working. The fuses all look good. I saw some previous posts about a turn signal switch, however when the turn signal is switched on and the wheel is turned you can feel the click shutting the signal off. I don't really know where to start. Help?

Thanks
Steve

Try the actual fuse itself. Mine had a bit of un-noticeable corrosion on it, a brand new fuse solved my issue.

The under dash one right?

I had this same problem last week. After checking the fuses and making sure the grounds were clean, I changed the turn signal switch. That fixed the signals but I still didn't have brake lights. I changed the brake light switch and all problems were solved. I'm seems odd for both switches to go bad at the same time but it sure sounds like you're having the same trouble I was having. My yj has been sitting out in the weather for the past five years so I wasn't surprised it was both switches in mine.
Good luck!

I just had this problem last week, also. I had my dash pulled back changing the speakers out and when I put everything back together the signals and brake lights didn't work. I checked all the fuses and ground but they were good. I decided that something had to have come unplugged when the dash was apart. It took me awhile but I finally found the culprit. There is a connecter that is on the steering column behind the dash. It sits at about 2 o'clock when looking from the drivers seat. If you have ac, you will have to tear the dash cover off to get to it like I did. Without ac you might be able to get to it from underneath. I plugged it back in and everything worked again. Hope this helps!

Ok I'll start with the brake light switch and see. I do have anther question though, at the top of the under dash fuse panel I noticed two round (relays?) one is marked haz and one is marked turn. Anybody have an idea what these are for?

I was wondering this as well as I had the dash out a week or two ago to change the ac condenser but they were working fine after. Something may have worked loose though I'll start here then change the switches.

Do you remember which connector it was i remember several being there. 2 circular
Ones and one square one guessing the square one though.

It is the only one attached to the steering column in that 2 o'clock area. It is long and flat. I just took off the front panel of the dash to get to it. Takes about 5 minutes.

Nice! Free and easy fix For your other question about the two round things at the top of the fuse box, they are the flashers for the turn signals and hazards. If they go bad, just unplug them and replace. J C whittney or someone like that sells flashers that play songs when you signal
Take care
