Hazard/Indicator problem

[impala]

All on its own and without ignition on the hazards start flashing - not normally but a fast flicker. Put the hazard flasher switch down and the hazards flash normally. Switch back up and the flicker resumes and neither indicator works. Only way to stop the flickering hazards is to remove the relay which obviously leaves you with nothing. Is it the relay? I've checked the contacts and they all appear OK. I've looked inside the relay and it all looks OK. Any ideas?

Could be am alarm fault. The alarm siren probably isn't working so just the flaser warning.

Try locking/unlocking.
Bonnet switch.
Water in well behind left rear wheel where to tilt sensor is.

Any more ideas anybody?

Top man Brian,
It was the bonnet switch. Must of had some corrosion in it. Gave it a few in/out manually and it's all back to normal.
Many thanks,
Dave
