Sounds like a problem in the indicator switch it self, start with back probing for current leak at the back of the switch, it sound s as if the switch is activating bout side at once and not actually switching on the hazards.

You need a multi meter, un plug the switch and check continuity between the main power wire and each signal wire, if you have continuity down both paths with the switch set on left turn the switch is faulty.
