 Thanks for the additional information.  I would conclude that your problem is almost certainly a defective Hazard switch rather than the Hazard flasher.  Usually the root cause is corrosion inside the switch.  This can create bizarre and ever-changing symptoms, including the blinking of Hazard/Turn lights even when the switch is in the Off position.  Note that all the Hazard/Turn lights on a side are normally wired together.  If only one light works sometimes, you have additional problems, probably in the socket of the non-illuminating light.  And any 'creative' rewiring by a previous owner can really confuse things.

Occasionally a Hazard switch problem goes away if one exercizes the switch a few tens of times.  This is usually only a temporary cure.  It is possible to remove and disassemble the switch, clean it out and lubricate the electrical parts with dielectric grease, then reassemble and return the switch to the car.  Unfortunately, a vital bit of the plastic switch body will often break during the process, and if this cannot be repaired, the switch must be replaced.

Virtually all of the original switches were used up many years ago, and any remaining survivors are now both rare and expensive.  Delta Motorsports sells an inexact replacement that works perfectly and seems far more reliable than the original, but which has male blade terminals rather than the male pin terminals necessary to mate with the car's wiring harness.  Delta provides suitable female blade terminals with their switch, but incorporating them requires modifying the wiring harness.  As far as I know, no one makes an adapter that would interconnect the wiring harness and Delta's switch.
