Which relay under the dash is the turn signal relay?

SOURCE: turn signals and hazzards come on but won't flash.

you say you replaced 2 relays , have you tested or replaced the turn signal flasher ? location left of the steering column , under dash .

SOURCE: NO TURN SIGNALS-BUT FLASHERS WORK

PROBLEM WAS FLASHER SWITCH WHICH HOUSES RELAY FOR TURN SIGNALS AND FLASHER UNIT--IT IS SOLID STATE AND WORKS WHEN YOU TAP ON IT--ORDERED ONE--IT SOUNDED LIKE A DIFFERENT RELAY BECAUSE SWITCH IS ABOUT 6 INCHES LONG AND EXTENDS BEHIND RADIO/CD/TAPE PLAYER--WHICH IS EASILY REMOVED (PUSH ON 2 SIDE TABS AND THEY POP OUT-GRAB THEM AND PULL ASSEMBLY OUT--PUSH RELAY OUT FROM BEHIND TOWARDS YOU--UNHOOK AND REPLACE--A 5 MIN REPAIR
GOOD LUCK

Try pushing the emergency flasher button in and out a few times.Dirt and liquid can get inside the turn signal switch, causing the contact problems. This is a common problem, and replacement of the switch might be nessesary
