Default Door open warning on dash

Hi all.

Here's the scenario. All doors, boot and bonnet are closed but the dash shows a door open warning.

When I lock the car I get the single horn sound indication a door is open, but all closed. I cant lock the car because the alarm goes of after a short while.

Odd. When travelling yesterday the light went out when turning right.

Now the bonnet switch on the slam panel has lost its rubber cover a good while back (it fell off into the engine bay and sitting on the undertary somewhere) so I'm thinking the exposed switch may be the problem however with the bonnet open and the switch fully pressed down to fool the system into thinking the bonnet is closed, the warning light on the dash remains on.

Anyone any ideas? Will T4 pinpoint the problem?

Personally I'd say it's the bonnet switch; the internals have gone kaput etc

Remove it, unplug it and see if the light goes out etc

If not, then give all the locks a good clean out with WD40 to rid them of any grime/water etc... Let that dry and then respray with lithium grease and see if that helps

I had a similar thing, turned out the switch was ok but a wire had broken going to the switch

Cheers for the replies. I removed the bonnet switch. It looks like some water has got in, no doubt because the rubber cover is missing, so a quick blast of WD40 and a clean of the contact and yippee, we are back in business!

Ill pick up a replacement rubber cover from a scrappy this week.

Surely you mean a vehicle recycling centre!

Glad you got it sorted.

Yes I was corrected before but he called it "Auto salvage".
