AU Hazard Lights Flashing

[SpannerHappy]

After degreasing the engine bay I had the same problem with my 1999 AU millennium XR 6 Fairlaine .
The hazards lights developed a mind of their own, and would not switch off.
Someone this forum suggested switching off the alarm module and unplugging its cable. Whoever it was who suggested this was SPOT ON!
Because the plug is on top of the module and the grommet was no longer water tight because of its age, moisture had entered into the connection socket.
An afternoon in the sun with the bonnet open and the cable disconcerted fixed the problem. Now All good Again.
