No turnsignals or hazard lights

There are flasher units that make and break the circuit to cause the lights to flash. Those could be faulty. Also the switch could have failed. It's easy to replace the flashers but you'd better diagnose the switch before jumping into replacing that. You may want to find an auto electric shop or a Subie specialist for help.
