door open light keeps blinking

[clarkie]

i cannot lock my door from the drivers door or the fob as it just opens back up on its own like the door is not closed properly and recently the doors open light on the dash keeps flashing on and off at me as im driving along and iv pulled over numerous times to make sure bonnet, boot and doors are all closed properly but it still comes on... im wondering if its something to do with the locks not working...

any help with the locks would be great too....

I had this. It turned out to be the bonnet.

IIRC the little plunger that breaks the circuit has some adjustment in it.

Boot one is a favourite too, the little white plug on the lock mechanism tends to get knocked loose as stuff goes in and out of the boot. I'm ashamed to say mine is held in place with a bit of Rizla packet after previous owner mashed the clip with a baby buggy.
