Measure resistance.

Is resistance 5 ohms or less?

Yes
RECONNECT indicator flasher. GO to DA9.

No
SERVICE Circuit 385 (W/R) for open circuit. RESTORE vehicle. RETEST system.

DA9 CHECK INDICATOR FLASHER OUTPUT

I'll bet dollars to donuts that the multi-function switch needs to be cleaned or replaced.

If you move the lever and the signal doesn't come on, try fiddling with the hazard/flasher button on the column.
I took mine apart and cleaned the contacts. Now it works fine.
