Thanks to both Chris and Dave for your replies. It defies logic but no matter how I try, I cannot get the boot open despite using the key manually or holding it anti-clockwise, that only makes the front windows come down. Re the o/s/n rear door, handle is not floppy, but nothing happens when you pull it. Have a feeling the main issue is the wiring but will struggle to access it with a locked boot. Thanks again for your help.
