When the head lights are on, the left signal light in the dash comes on and stays on. When the signal lights are used the light will then flash normally. Checked bulbs and changed flasher. Any help as to were the short might be would be appreciated. _______________________________________________
There is probably a poor ground connection near the tail/turn light socket. Tail light current can not get to its own ground near the lamp socket so it continues backwards through the turn light filament, then through the dash turn signal monitor filament and finally to ground.
Look for a ground wire from the light socket to the chassis, attached by a screw. Remove the screw, wire-brush the wire terminal and the mounting surface, and reattach securely.
Good Luck.
