Turn signal problems on 75 duster

YOU NEED to take some time out and LEARN HOW TO troubleshoot.

Get a test lamp, couple of alligator clip jumper wires and a decent multimeter and learn to use them. If you post the model of the meter on here and or a photo we can step you through some things.

Access the turn signal switch connector where it enters the steering column, and set up to back probe the connector. Make a little pictorial and diagram the connector, the wire colors, and what they do

Basically what you have going to and from the switch:

IN:

Switched brake lights power

Turn flasher power with key in "run."

Hazard flasher power at all times

Outputs:

Left rear, right rear signal/ stop lamps
Left front, right front signal lamps

You can backprobe the connector as you cycle the switch through functions, actuate the brake pedal and hazards and look for what voltage appears where
