indicator relay

[pitch1]

Hi all, I've got a ticking noise in the boot of my 97 gen 3 surf thats driving me mad. I've pulled off the plastic on the passenger side and its coming from behind the lights. It sounds like my indicators but quieter. All indicators are working fine. Not 100% sure but think its a relay (long black thing with microchips on it lol). Is there a way of fixing it or do I need a new one and if so where can I get one from? Any help would be greatly appreciated
Cheers
Andy

just had a thought: It could have something to do with the electrics on the towbar


its ok friends found the problem it was the relay but for the towbar thanks for looking
