Help,show me the light(Off).Electrics problems boot/ alarm

[me beautiful]

The situation:
The boot switch light is always on. Therefore the car think the boot is open ( silly billy).
Result:
Tha alarm is not on as as soon as a lock is faulty the alarm is dead (was told).
The boot won't open with the switch or remote as it suppose to be already open.
I get really frustrated as I have been looking everywhere, I have changed the switch in the boot barrel thinking it was the fault, nop.
I have taking the boot lid carpet off to check the wires, nothing strange there either.
I have open the central console and dissassemble it ( well, partially as I didn't open the blak plastic with the switches), fiddle with the boot switch, nothing looking bad there as well.
Disconnected the battery for at least 5 minutes.
I don't know where to look anymore, what to do, what to replace.
Now, I need some serious advice there, will it be after all as simple as Resetting the whole system through the dealer?
Will it be a shortcircuit
Will it be the console itself?
Me?
The RSR light is always on as well, could it be a connection?
Help. Thank you. Olivier
Oh, the car start to get hicups now on the hyghway, but I have bubbles in the system and canno find where from,yet... I just put this in just in case all might be related to a servo or what ever electric involve.

HI
I had a silamar problem with a car , the car was new , I reckoned it was the centre consoule switch unite because is all connected . If all connections are checked I would run the car on STAR Diagnosticts and see if it can give you any info

thank you. The console will be expensive though. Well... What is star diagnostic? How did you get sorted by the way? Thank you.

Star Diagnostic System (SDS) is what the dealer uses. A good independent may have one also.

You can buy it, but it would cost more than your car is worth.
