Turn signals won’t work

[allenjdeg2]

1969 S2 FHC turn signals suddenly don’t work. The hazard lights work at all locations, but no lights at the rear or front with the column turn signals. Installed a new flasher unit TF550 and still no turn signal response. All fuses look good. Any help would be appreciated.

You need to get hold of a circuit diagram for the car. Then you need to progressively test with a meter the indicator paths/parts which are not common to both indicator and hazard, to see where you do and don't have voltage along the path according to the circuit diagram.
Finally, if you isolate where you suspect the fault to be and then temporarily bypass that point, if the light(s) light, then you have probably found where the problem was.
You also need to consider whether there are any non-standard parts fitted:- for example, LED bulbs do not always work with old style bimetallic flasher cans.

Check the wiring to the stalk switch...possible a wire has become loose...
