electric switch (door)

[shropshire lad]

I'm getting an almost continual clicking of what sounds like an electrical switch as I drive along. It is coming from the centre of the car (maybe the door lock ) . Everything seems to be working correctly - no loss of power , doors lock and unlock etc.
I first noticed it after washing the car , but have since made a 100 mile journey and its still there .
Any ideas what is causing it.

Probably caused by the courtesy light switch near the sill

Thanks for the reply.
Is it likely that the contacts are dirty or wet and a clean will see it right ?

It's more likely that the pad has fallen off your door. The small switch is supposed to be pushed in by a small rubber pad on the door. These can fall off in time, leaving a pin which is pushed in by the door, but not quite enough.

The best solution I found was to go to homebase/B&Q and pick up a pack of small rubber pads used under to stop small furniture rubbing on wood floors etc. They're transparant and almost exactly the same size as the original rubber pad. You get about 40 for £1.50 so not expensive and you have plenty should it happen again. They are self adhesive but the glue isn't weatherproof so its a good idea to put a bit of superglue on the back as well to hold it in place. There is a small groove on the door where it needs to go.

It would be a good idea to pull the switch out and clean it up with some contact cleaner while you're down there as they take a bit of a batteringand are usually covered in rust/copper oxide. If it's too far gone, they can be easily purchased from Demon Tweeks (Ford type door pin).

Hope that helps!

Thanks Nick - spot on .
Couldn't find the said pads in Homebase , but I know what the problem is now and its easy to fix.
