I have replaced the relay, the multifunction switch and checked all my fuses and I still have no signal lights at all. My hazards work like they show so I am not understanding my problem. Can someone guided me in the right direction as to where to look next for an issue? 2006 Ranger

 

Do they come on and not flash, or do they not turn on at all ?

 

they do not come on at all.

 

When the hazards are on, have you verified that all 4 corners are flashing, or just guessing they do because the 2 in the dash are flashing?

Do the brake lights work ?

 

the brakes work like they should, and all 4 corners work when hazards work

 

Test Fuse 20 in Cab Fuse box, should have 12volts with Key on
Pull out the fuse, turn key on, test both fuse connections for 12volts, one should show 12volts, if not then that's your problem
4-ways use a different fuse, as do brake lights, they always have 12volts, turn signals only have 12v with key on so different power paths to flasher

2004 and up Rangers use the Smart Junction Box(SJB), the cab fuse box is part of SJB

These were known to get corroded connections, there are 4 large connectors on the SJB

Picture of SJB and connections seen here: https://www.therangerstation.com/tec...-modification/
If Fuse 20 doesn't have 12v then could be failed SJB, internal issue
If fuse 20 does have 12v then could be wire connection OUT to flasher thats the problem.

Extreme example but it happens
