Boot not closing/opening with difficulty

[Tuppence]

Hello,

 

My Lexus IS250 SE (2005) has been giving problems with opening the boot with the button and the key for about a month.  Next it has started not closing, so the little red light is always on when car is switched off.  Battery goes flat, I found out last year.  Not sure how it corrected itself last year but problem now here again.  Driving around the other day the unlocked boot locked itself and the light went out.  Decided I can't use the boot anymore until at least after my trip in Nov when car has to be left at airport.

Anybody else had these problems?  What was solution, what's causing it?

Thanks in advance.

I'd say it's got to be a loose connection somewhere.

But if it was a loose connection, that would not cause it not to close when slammed shut??  Thanks for your reply by the way.
