1999 F350 Super-duty 4x4
All turn signals stopped working simultaneously. I checked and the fuses seem to be okay. Would this be a multifunction switch issue, or is there something else to check? If so, how difficult is it to replace? My local dealer sells the part for about $135.00

 

Are the hazard flashers still working?

The multi function assembly is fairly easy to replace with only a few basic tools.. The local dealer still has some room to work, and you should be able to get a MF switch for about 90.00or so (plus tax) aftermarket, or at a reduced price from dealer...

 

Thanks for the response.
Yes, the hazards are still working. So are the other components controlled by the switch (hi-beams, wipers).
