No turn signals

Hello all,

I have a 1996 Bluebird All American RE 8.3 cummins, 40ft pusher. My wife and I full time in our conversion.

Having issues with my turn signals.

I have hazards, headlights, running lights, stop lights, but no turn signals.

I've replaced all the bulbs, I believe all the fuses and 4 way flasher fuse.

I'm stumped as to what's going on. I can't find a wiring diagram to save my life.

Any help would be much appreciated.

if all the bulbs were replaced and you used the exact replacement with dilectric grease and still have the same problem then I would go with the turn signal selector switch?
mine is steering column mounted and i have to wiggle it a little bit to make them work?
but then again mine is an 86?
i would say not making good contact in the steering column?
where is you turn signal selector switch?

Tuen signal selector switch is in the steering column. I replaced it when I bought the bus as I lost turns and hazards back then.

It's a possibility it may be bad, but hazards work fine and it doesn't look like its inoperable. Clicks in place solid.

But contacts may be bad. I'll have to see if I can test it somehow.

Thanks for the reply.

did you replace the entire steering column or did you open the column up and replace the switch itself?

Simple place to start is to check the ground connections at each turn signal.
You should also have 12v+ at each location when the switch is in the left or right hand position. Best to use a meter. Clean up or find new ground locations.

I replaced the flasher relay. Both 20 amp inline fuses.

Replaced all 3, Bosch 5 prong fuse relays.

Replaced my trailer wiring harness.

Replaced all bulbs involved with turns signals and brake lights.

Just cant figure it out.

Thank you.

john might be correct with the grounding issue.
my entire bus is grounded to the body and i have have to clean and or change screw mounting holes just to give mine good metal to GROTE plastic bases.
the screws are the ground for me

Some newer vehicles use separate flashers for the turn signals and the hazards.
