Turn Signal and hazards not working. Need Help.

I have a 1991 Blue Bird TC2000. My turn signals and 4 ways stopped working completely. Nothing at all happens. No noise, no relay clicking, Nothing. I have tried to find a turn signal relay, but haven't had any luck. Can anyone help me with this? Thanks in advance.

IIRC, the turn signal and hazard flasher units are in the electrical compartment accessed outside just below the driver's window.

The hazards should work regardless of key position so I don't think it has anything to do with the key switch.

If this is something that all of a sudden happened then I would make a guess that something has become disconnected.

If you have been messing around under the dashboard or moving wiring bundles around I would lay a bet something has come adrift.

I would start by finding the flasher units just to make sure both units didn't go south at the same time.

Then it becomes a search for where something has come adrift.

To pinpoint the location you need to remember what you were doing the last time you knew for sure the lights worked and what you have done since.

Good luck.

Thanks for the reply. That makes a lot of sense. I was in the middle of switching out some gauges when this all started. A couple of things could be the cause. I was disconnecting some old gauges and I thought I might have disconnected a ground that was part of the turn signals. I tested the ground that was going to the actual turn signal lights on the dash and it was still properly grounded. I might have disconnected the hot wire that was going to the turn signal by accident. I'll have to search for that. Another possibility: I decided to drive to the store while my entire dash cluster was disconnected. I tested the blinkers before I left and they still worked. After I took off I remembered that my mechanical oil pressure gauge was disconnected. (Not Smart) I stopped and of course there was some spilled oil in my dash. It was after that the turn signals no longer worked. I figured I must have shorted something out. Turn signal relay was my thought. I just can't find it for the life of me. I've looked all inside my electrical panel under the drivers window.

When you say find the flasher unit, are you talking about the relay or something different? Thanks again.
