Restoring 83 911 targa, bare metal repaint. Cleaned and repainted rear taillight housings and reinstalled the housings and front light housings. New bulbs. checked connections twice (compared with "before" digital photos). Also installed new turn signal switch (old one kept turning on the brights). All the proper bulbs light up with lights on. Brake lights work, emergency flashers work, but turn signals dead both right and left. Fuses check out. Any ideas what to do next??
