I know it is typical to read this but I have read few advices.

Rear wiper and wash are working fine.

All rear lights except compartment lights are working.

When open the boot, dash warning light does not appeared to be on. Only four doors opened are working.

So what is the verdict? Latch or control panel?

Look forward to hear from you.

Thanks

Check the Interior lights , are they working ?

Check the fuse if they are not working , Few days ago I was installing LED in the boot and all interior light stopped working turns out it was a blown 7.5 Amp fuse . So it might worth checking that 

Locking and unlocking boot is working fine. Thank you for your help, Mike

Fuse's ok. Interior lights at front and above back seat are working.

I'll look up the latch from eBay.
