Boot light on dash and alarm going off please help!!? Driving me mad!!

Ok thank you. When you say dried the whole area you mean the wiper motor including the. Boot locking mechanism?
 
Yes the whole area around the wiper motor. Where the washer liuid tube is and also all the pannelling.
 
Ok. Thank you very much for your help. Will give it a blast tonight.
 
Sorry again. Would somebody be able to post a picture if the switch I've got to clean. I can' see any pictures on Google of it on a a3. Will it come away from the car?
 
Well that didnt' go to plan. Ever since this has started the issue with the boot my battery is flat! It' like it' being drained! I put my key in it was that flat the dash didn' even light up and there was no loss to even pop the boot open! Any suggestions would greatly be appreciated thanks
