Turn signals not working

[F-350Fireman]

turn signals worked fine all summer, but now with days that are 50-65 and so far rainy they dont work. hazard lights work fine and they light up when the running lights are on. and theyll come on when the turn signal handle is held down over a few minutes. any suggstions?
thanks

Unplug the flasher and check if you are getting voltage at the socket with a test light or voltmeter when you use the turn signal handle. If not, it's probably in the turn signal handle assembly. If yes, replace flasher or it's a wiring problem between the flasher and the bulbs.

I have the exact same issue that just started. On 2005 I think the procedure is to replace the turn signal arm. Still researching.

Also if it happens again check the contacts on the bulb and housing, sometimes corrosion builds up and makes them work intermittently as you described.
