Hi, bus is a 76. I have no indicators and no hazards. What could cause both to stop working? Fuses all seem good.

Thanks for the tip, it appears the problem is with the switch. If I press on the switch to one angle the switch starts to work and the turn signals also work. Is there an earth on the back of the switch or does it earth through where it mounts?

There should be a wire that attaches to the case of the switch from the back of the instrument cluster to ground it. Reach up under there and squeeze the plastic part with all the terminals on it back into the switch and put a zip tie around it to keep it there.

Idea Tip: sweep off the cab floor mat before starting this job so you won't be digging through gravel and dirt if it pops apart and some springs, etc.. go flying.

I removed the switch and itcame apart in my hand, the earth wire was secure. I put it back together inc the little ball bearing behind the spring. It’s still not working. Like I said earlier it works if I apply sideward pressure to the switch as if it needs to be contacting the body for it to work. Am I looking at a new switch?

May not apply, but every time one of my Benz's had no indicators I found it was the hazard switch. Dissasemble, clean, buff all the contacts, reassemble and it was good to go.

Some critical sliding contact may have leapt out and scurried away, there's 3 springs, 2 copper contact sliders (look like a funny staple ] ) and the detent ball, you might need a new switch, but lets do some testing first.
Break out your test light or meter and probe for power at terminal #30 (red), then with the key on probe terminal #15 (green), both show power? Now with the knob pushed in probe the + terminal (white), there should only be power when the key is on, now pull the knob and + should have power even if the key is off. If all those check out OK we'll move on to the other side of the switch and check the signal wires, an ohm meter works well for this. L, R & 49a should all show no continuity to each other when the knob is in, when the knob is pulled all 3 should be connected together.
If all that tests OK probe the + wire at the relay (knob in and out, key on and off), if there's no power there the wire is suspect.

The diagram below is for a 72 bus, the signal circuit is the same on all year Euro models and 72-79 North American versions, the fuse locations may differ over the years but the wire colors and terminal numbers remain the same.

Cheers BD, I ended up buying a new switch, the problem is this has an extra tab. My hazards are now working but my indicators are not at the stalk?

Then off to the fuse box to find out why, no #15 means no turn signals.

Thank You Samba. I was taking my bus to get inspected today and on the way the signals stopped working. Using my phone access The Samba a quick search of Turn Signals led me to this thread. Sure enough the switched had popped open. Even with no tools I was able to get the switch out under the dash and pop it back together long enough to pass inspecton. I then got this cool sticker for the front of Da Bus.

Put a zip tie around it to hold it together.

Thanks Tcash. The zip tie seems to be all it needs it to be held together firmly. The orignal crimps just don't engage the back anymore.
