Cadillac Repair: cadillac etc 1999, turn signal flasher, turn signals

Question
my turn signals quit working - both sides, front and back, all at once

Answer
replace the turn signal flasher under the dash up along side of the steering column.

You will see 2 relays, Remove one and see if your hazard flashers still work. If they DO, You found the correct relay. If they DO NOT work, Replace the OTHER relay. LOOK hard it is up there pretty well hidden.
