How to fix a bad turn signal switch?
So, the case could be one of these: 1 A faulty hazard light flasher 2 If the flasher if fine, it could be the fuse 3 A bad connection at the turn signal switch 4 A loose connection in the circuit that connects the turn signal switch and the flasher 5 A electrical open circuit/ short circuit in external lights wiring
Why do my hazard lights work, but not my turn signals?
Turn signals only work when the ignition is on; hazard lights work whether the ignition is on or not. The two systems have separate power supplies, so they have separate fuses. You may have a blown fuse. Different vehicles use different circuits, and it is not possible to accurately diagnose the fault with the small amount of information provided.
What to do when your turn signal Flasher does not work?

What happens when a light switch is turned on?
When the switch is initially turned on, electrical current flows through the flasher unit to the bulbs. When this occurs, heat builds up in the flasher unit. When the heat reaches a predetermined temperature, a metal strip within the unit stretches due to the heat and breaks the electrical circuit turning the bulbs off.
What causes a turn signal to be inoperative?
The usual cause of inoperative turn signals is a defective bulb or flasher unit. Prior to performing extensive diagnosis, check the vehicles fuses to ensure they are not blown. Some vehicles utilize two fuse boxes, one in the passenger compartment and another under the hood. Consult your owner’s manual for fuse box locations and fuse ratings.
