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
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.
