Turn Signal Flasher ??????????

:confused: hey all a friend has been driving around in her Nubira for three months now with out turn signals ive looked in the normal place , under the dash in the fuce block but there is no fuce block under the dash i looked under the hood wich most manufactures are moving the fuce /relay power box to but still no sign of a flash .
does it take a normal 2 prong flash or a three prong ??
thanks any sugestions would be apriciated
