The flasher relay in the 123 is clipped to the front of the
shifter housing under the wood and does both the 4 ways and the
blinkers, all routed through the 4 way switch. If it doesn't make
good contact in the off position it will cause the blinkers not
to work. Found that out many times already due to my habit of
setting cups on the center console switches when I get out.
Sometimes tips the switch just enough so the blinkers don't work
when I get back in. Probably not the problem in this case since
he said that he worked the switch back and forth quite a few
times and it didn't help. I'm assuming he meant the 4 way switch
and not the blinker switch.
Loosen the bolts and use contact cleaner on the ground points
behind the instruments? Can't hurt.

Could be the ground, or the flasher relay. Not sure if it lives behind the cluster or if the W123 had it built into the 4 way flasher. Removing the switches and some contact cleaner helps at times.

Well, if it was a fuse problem, that would work. However the mentioned systems
are on more than one circuit, and some things on the mentioned circuits DO
work. I did, however check the fuses and alles gut.
So, I am still looking for a common B+ feed.
Cluster lights work. 4 way flashers work, but turn signals don't. Tried
cycling the flasher switch, maybe 50 times, with no change.
Maybe I am chasing a ground.
