Electrical issue after car is locked

[DennisF6]

Hi all, 

I have a FG XR6T Mkii with 125,000k on it, I'm the original owner. 

I noticed this morning after I called into the local shops that when I got into my car after leaving it parked and locked for about 30mins it had developed some sort of electrical noise when I unlocked it and sat inside. The noise sounds like a switch turning on and off and is coming from behind the stereo area. 

I tried sitting in the car and locking it and unlocking it however that made no change. I went for a drive and noticed nothing different then parked it and locked it for about 5 mins, no noise, got out and left it for about 10mins and when I unlocked the car and sat inside the noise was there again. 

No I've had the car locked and sitting for approx 45mins since the last time I heard the noise so I thought I'd go and check, nothing, no sound at all.. 

Anyone come across this before?

Extra info, I removed one by one all fuses and found that the noise would stop when I removed the 10A fuse for the HIM, ALARM, Diagnostic Connector

Anyone have any ideas regarding this?

It should be a  HIM, ALARM or Diagnostic Connector issue then.

 

Nah just kidding mate. sorry, but I have no idea where to start. I am just bumping your post to get others to reply.
