Turn signal troubleshooting, Looking for tips where to look/start first... Options

[campbellcj]

Hey everyone - I have a problem I've been meaning to get resolved for some time but I'm not sure where things went wrong. Once I reinstalled the lights in my car after they had been out for several years of dedicated track use, the turn signals aren't working right; however, the puzzling part is the hazards blink fine, parking lights work, and the lever-actuated 'park mode' also works on both sides. This leads me to believe I pretty much connected things right and the stalk switch seems OK too, but obviously I went astray somewhere.

It's been a while but IIRC I did already try swapping in a different flasher relay to no avail. Also FWIW the stalk switch and dash wiring had not been removed/reinstalled, only the actual lamps up-front and their fuses. So the interior wiring should be basically unmolested (by me at least).

This car is painful to work inside due to full rollcage and immovable seats. If any of you has seen this specific fault before I would massively appreciate a tip before I start poking around at every single wire (again)! Thanks!
